Module 2, Amber and dark lagers

2.1.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Vienna Lager is an amber lager with the flavour of toast and the weight of an everyday beer. It looks like a beer that will fill you up. It does not. That gap is the whole style.

The physical tell

Hold it against a light. You should see red in the amber, and you should see straight through it. Then take a mouthful and pay attention to weight rather than flavour. Your eyes predicted something substantial. Your mouth reports something light. That mismatch is the field mark, and no other amber beer does it quite this way.

Where it came from

Anton Dreher first brewed it at Schwechat, just outside Vienna, in 1841. That is the same year Gabriel Sedlmayr brewed the first amber Marzen in Munich, and it is not a coincidence. The two men had travelled through Britain together in the 1830s, studying how British maltsters dried grain with hot air instead of direct smoke.

Indirect kilning let a brewer choose the colour of the malt. Dreher chose a light brown. Sedlmayr chose a darker one. Two beers, one trip, one technology, and the same year.

The style then almost died in Austria. Pale Pilsner took the market, and Austrian brewers followed the money. It survived because Austrian and German brewers took lager brewing to Mexico in the second half of the nineteenth century, and because American brewers picked it back up in the 1990s.

2.1.1.2 One malt, and then restraint

The colour comes from a kiln set between two other kilns. The lightness comes from stopping there.

Decision one: build it on Vienna malt

Vienna malt is barley dried a little hotter than pale pilsner malt and a little cooler than Munich malt. That narrow gap is the entire style. The grain browns enough to taste of toast, and not far enough to taste of bread crust or chocolate.

The malt is also named after the city, which tells you how central it is. If a brewer swaps it out, the beer stops being this beer.

Decision two: stop there

No caramel malt, no roasted malt, and no large grain bill. The strength stays near 5%, and the beer is fermented out almost completely. Brewers call that high attenuation, which just means the yeast ate most of the sugar. That is why an amber beer finishes dry and light.

Restraint is a decision, not an absence. Every amber beer that tastes heavy got there because somebody added something. This one is what you get when nobody does.

The traditional slow step

The classic method is a decoction mash. The brewer scoops out part of the mixture of grain and hot water, boils it separately, and stirs it back in. That deepens both colour and toast. It costs hours and fuel, so many modern breweries use good malt and a single mash instead.

What it is not

2.1.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop.

Order one if you already like any of these

• Toast, especially the darker corners of a slice. That flavour is the main event in the glass.
• The skin on a roast potato, or the browned edge of a grilled onion. Same browning, same chemistry.
• Water crackers, digestive biscuits, or plain shortbread. Gentle grain flavour without sweetness.
• A drink with some flavour that you can still have two of. This one is built for exactly that.

Leave it for now if either of these is true

• You want hop smell or real bitterness. At 18 to 30 IBU the hops balance the malt and never lead.
• You want a big rich beer to sit with for an hour. This one is deliberately light, and you will find it slight.

Ordering it

Take the full pour. At around 5% this is a session strength beer, and a taster glass tells you nothing about how light it feels. The name is easy to say out loud, which is not true of everything in this module.

Five you can actually buy

2.1.2.2 Food, faults, and the Mexican question

The Mexico story is real history attached to the wrong bottles, which is the most common way a beer fact goes wrong.

Food

What does not work: very hot chilli, strong blue cheese, and rich chocolate desserts. All three simply flatten the beer, because there is not much weight here to push back with.

What a good one does

Bright reddish amber with a large off white head that holds. Toasted malt on the nose, with nothing burnt and nothing sweet. Soft at the front, then clean and dry at the swallow. Above all it should feel lighter than it looks.

The faults this style suffers from most

A sticky sweet finish is the common one. If the malt keeps going after the swallow and coats your teeth, the beer was either not fermented out or was built with caramel malt for a quick colour. Either way the mouthfeel goes heavy, and mouthfeel is simply how the beer feels rather than how it tastes.

A slick butterscotch flavour is a separate fault called diacetyl, which comes from a fermentation that was rushed or cut short. Lagers show it plainly because nothing else is in the way.

Then there is age. This beer has very little hop and very little alcohol to protect it, so an old one tastes of wet cardboard with a dull sweetness behind. Check the date on the box.

2.2.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Marzen is a strong amber lager that promises sweetness and then finishes dry. That gap between what the first mouthful suggests and what the swallow delivers is the entire style. Everything on this page exists to produce it.

The physical tell

Hold the glass up against a light. It glows orange rather than yellow, and you can see through it cleanly. Then take a mouthful and pay attention to the swallow. The rich malt flavour does not fade, it stops, and your mouth is left dry rather than coated. Colour plus that abrupt dry ending is the field mark.

Where the name comes from

Marzen is German for March. In 1553 a Bavarian decree allowed brewing only between 29 September and 23 April, because summer brewing in a world without refrigeration produced spoiled beer and burnt buildings. So brewers made their last batch of the season in March, made it strong so it would keep, and stored it in cold caves under ice all summer.

By late September the cellars had to be emptied before the new brewing year started. That is why an old, strong, well kept beer became the beer of autumn festivals.

How it became the Oktoberfest beer

Oktoberfest itself began on 12 October 1810, as a public celebration of the royal wedding of Crown Prince Ludwig of Bavaria and Princess Therese. Around 1841 Gabriel Sedlmayr at Spaten developed the amber lager version of March beer. In 1872 Josef Sedlmayr served a strong Marzen at the Schottenhamel tent, and it became the festival standard for the next century.

2.2.1.2 Two decisions, and a slow one

The colour and the toast in this beer come from the kiln and from the kettle, not from anything added later.

Decision one: build it on Munich malt

Munich malt is ordinary barley dried in a warmer, wetter kiln than pale malt. The extra heat and moisture let the sugars inside the grain brown before it dries out, the same browning that happens to the crust of a loaf. That single ingredient gives the beer its amber colour and its bread crust flavour.

What is not in there matters just as much. No caramel malt, no roasted malt. The BJCP is explicit that caramel and roast flavours do not belong in this style. If you taste toffee, somebody has taken a shortcut to the colour.

Decision two: boil part of the mash

The traditional method here is a decoction mash. The brewer scoops out part of the porridge of grain and hot water, boils it in a separate vessel, and stirs it back in. That extra boiling deepens the colour and pushes the toasted flavour further. It takes hours and it costs fuel, so many modern breweries skip it.

The slow decision

Ferment it cold with lager yeast, then store it cold for months. Brewers call the storing part lagering, from the German lagern, which just means to store. The original March beers sat under ice until autumn. Modern versions do not need that long, but they still get far more time than an everyday lager.

One more thing makes the style work: the beer is fermented out almost completely. Brewers call that high attenuation, which just means the yeast has eaten most of the sugar. It is why a beer that smells this rich can finish dry, and it is the difference between a good Marzen and a heavy one.

2.2.2.1 The four neighbours

Colour sorts most of this family. Strength sorts the rest.

This is the one part of the course where looking at the beer does most of the work. Every style below sits at a different point on the colour scale, and the two that share a colour are separated by strength. Each has one feature you can catch without a lab.

• Festbier. Golden rather than amber, and much less toasty. If the beer in a tent is the colour of a Helles but stronger, that is what it is.
• Vienna Lager. Similar malt flavour to a Marzen but lighter in every direction: less body, less alcohol, a touch more bitterness and dryness.
• Munich Dunkel. Clearly brown rather than amber, and the flavour moves from bread crust towards chocolate. Usually weaker than a Marzen, which surprises people.
• Dunkles Bock. Darker and stronger again, with a heavier body and more obvious alcohol. If it is dark and warms your chest, you have left Marzen behind.

2.2.2.2 Will you like it, and what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop in season.

Order one if you already like any of these

• The crust of a roast, or the browned outside of a good sausage. That browned flavour is the main thing in the glass.
• Toasted bread with butter, or the dark outside of a soft pretzel. Same flavour, arriving by the same chemistry.
• Roasted nuts, or the skin on a roast potato. If browning is a flavour you actively look for, this is your beer.
• A drink with some weight to it that still finishes clean. This one has more body than a lager and less sweetness than you expect.

Leave it for now if either of these is true

• You want bitterness or hop smell. At 18 to 24 IBU there is almost none of either, and you will find it dull.
• You want something light to drink for an hour. This is a 6% beer normally served in large glasses, and it is heavier work than it looks.

Five you can actually buy

2.2.3.1 At the bar and at the table

One question at the bar sorts out a label that means two different beers.

Ordering it

The word Oktoberfest on an American tap handle tells you the season and not the style. It might be an amber Marzen or a golden Festbier, and both are correct uses of the word. One question settles it: ask whether it is amber or golden.

Take the full pour. This beer needs a little room and a little warmth to show its malt, and a taster glass gives it neither. At Oktoberfest itself there is only one size, the one litre Mass, and at 6% that is a serious drink. Order food with it and drink water alongside.

Food

What does not work: fresh salads, delicate white fish, and very hot chilli. The first two vanish under the malt. Chilli heat and alcohol together make the burn worse, and this is a stronger beer than it tastes.

2.2.3.2 Faults, the myth, and how to remember it

The naming muddle in this style is not a small quibble. It changes which beer you end up drinking.

What a good one does

Bright amber to copper, with an off white head that holds. Bread crust and light toast on the nose, and nothing burnt. Rich and smooth in the mouth, then a finish that is clearly dry. It should suggest sweetness without ever delivering it.

The fault this style suffers from most

A sweet, sticky finish. If the malt flavour keeps going after the swallow and coats your teeth, the beer was not fermented out properly, or the brewer reached for caramel malt to get the colour quickly. The guidelines are clear that a Marzen should finish dry, and a cloying one is a failed beer rather than a rich one.

A slick butterscotch flavour is a separate fault called diacetyl, which comes from a fermentation that was rushed or cut short. Lagers show it clearly because there is nothing else in the way.

Then there is age, which is a shop problem rather than a brewery one. Seasonal beer lingers on shelves, and a Marzen bought in February tastes of wet paper with a dull sweetness behind it. Check the date, and buy in the season.

2.3.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Munich Dunkel is a brown lager that tastes of bread crust and drinks like an everyday beer. Dunkel is simply the German word for dark. Everything surprising about this beer follows from the fact that the darkness costs it nothing.

The physical tell

Tilt the glass in front of a light and look at the thin edge. Brown turns red or garnet there, which black beers do not do. Then swallow and notice what your mouth does not report. No burnt bite, no drying grip at the back, no warmth in your chest. Dark colour with none of the consequences is the field mark.

Where it came from

Munich malt arrived in the 1820s, and Gabriel Sedlmayr at Spaten used it to make the first modern Dunkel in the 1830s. Bavaria drank dark lager as its default beer from roughly the 1840s to the 1890s. This was not a specialty. It was what a Munich brewery sold you on a Tuesday.

Munich Helles came later, in 1894, invented because pale Czech Pilsner was taking the market. So the pale beer is the newcomer and the dark one is the original. That is the reverse of what most people assume about German brewing.

2.3.1.2 Munich malt, and almost nothing else

One grain does nearly all the work here, and what the brewer leaves out matters as much as what goes in.

Decision one: build almost the whole beer from Munich malt

Munich malt is ordinary barley dried in a warmer, wetter kiln than pale malt. The extra heat and moisture let the sugars inside the grain brown before it dries, the same browning that happens to the crust of a loaf. Use enough of it and you get a brown beer that tastes of bread.

That is the difference between browning and burning. Burning happens at the surface at high heat and gives you coffee and char. Browning happens inside the grain and gives you toast and crust. A Dunkel is browned all the way through and burnt nowhere.

Decision two: use dark malt for colour only, if at all

A brewer may add a very small amount of roasted malt to deepen the colour. The Brewers Association allows it and says the roast flavour must stay minimal. If you can clearly taste roast, the brewer used too much, or you are drinking a Schwarzbier.

Too much dark malt also brings astringency, which is the dry gripping feeling you get from strong tea or grape skins. A good Dunkel has none of it, and that absence is what lets you drink a half litre without tiring.

The traditional slow steps

The classic method is a decoction mash, often done three times. The brewer scoops out part of the mixture of grain and hot water, boils it separately, and stirs it back in. Each round deepens colour and browning. Then the beer is fermented cold and stored cold for weeks, which is what lagering means.

One more thing keeps it drinkable: the beer is fermented well out. Brewers call that attenuation, which just means how much of the sugar the yeast ate. A Dunkel that is not fermented out becomes a sweet brown drink that nobody wants a second of.

What it is not

2.3.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop.

Order one if you already like any of these

• The crust of a good loaf, or dark rye bread. That flavour is the main event in the glass.
• A square of milk chocolate, rather than dark chocolate. Gentle cocoa, not bitter cocoa.
• Roasted hazelnuts or almonds. Browned and nutty is exactly what Munich malt does.
• Anything you have avoided because it looked too dark. This is the beer that fixes that idea.

Leave it for now if either of these is true

• You want the burnt coffee edge of a stout. There is none here, and you will find it tame.
• You want hop smell or real bitterness. At 18 to 28 IBU the hops only balance the malt.

Ordering it

Take the full pour, and a half litre if the bar offers it. This is a 5% beer built for volume, and a small glass hides what makes it good. It is also the beer to order when a friend says they do not like dark beer, because it argues the point better than you can.

Five you can actually buy

2.3.2.2 Food, faults, and the dark beer myth

This is the beer that settles the oldest wrong idea in drinking, and it settles it in one glass.

Food

What does not work: hot chilli, fresh salad, and delicate white fish. The chilli fights the malt, and the other two disappear underneath it.

What a good one does

Clear deep brown with a creamy tan head that holds. Toasted bread crust on the nose, with a hint of chocolate and nothing burnt. Soft and rounded in the mouth, then a medium dry finish. You should want another one immediately.

The faults this style suffers from most

A sweet, syrupy finish is the common one. If the malt coats your teeth and you feel done after half a glass, the beer was not fermented out, or the brewer overloaded it with caramel malt. A Dunkel that tires you has failed at its only job.

A harsh burnt edge is the opposite fault. That means too much roasted malt, and it usually arrives with a dry gripping feeling at the back of the tongue. At that point you have a poorly made Schwarzbier.

Then there is age. A slick butterscotch flavour is a fault called diacetyl, from a fermentation that was rushed or cut short. An old import tastes of wet cardboard with a dull sweetness behind it, and imported dark lager sits on shelves for a long time.

2.4.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

Schwarzbier is German for black beer, and the name is the whole of the description. It is the darkest beer in this module and one of the lightest. That gap between what your eye expects and what your mouth reports is the point of the style.

The physical tell

Lift the glass to a strong light and look at the extreme edge. A thin ruby or garnet line shows there, so the beer is very dark brown rather than truly black. Then swallow. The roast touches you once, briefly, and is gone before you set the glass down.

The second tell is weight. A beer this colour should feel thick in your mouth and it does not. It feels close to a Pilsner. Once you have noticed that mismatch you will never mistake the style again.

Where it came from

This is a regional beer from Thuringia, Saxony and Franconia, so eastern Germany and the northern edge of Bavaria. It was never a national style. Kostritzer, in the Thuringian town of Bad Kostritz, appears in inheritance records in 1543 and is the name most people meet first.

Goethe drank it while he lived in nearby Weimar. Wilhelm von Humboldt wrote in 1823 that Goethe lived on beer and bread rolls, and weighed up whether to have the dark or the light brown Kostritzer that morning.

Most of the Schwarzbier breweries ended up inside East Germany after 1945. The style stayed alive there and was little known elsewhere. German reunification in 1990 put it back on shelves in the west, and it has been spreading since.

2.4.1.2 Dark malt with the husk taken off

One change at the maltings explains how a beer gets this colour without the bite that normally comes with it.

Decision one: use dark malt with the husk removed

Roasted malt gets its colour from being cooked hard at the surface of the grain. Most of the harsh, ashy, drying compounds sit in the husk, which is the papery outer skin. Maltsters can strip that husk off before roasting, and the result is sold as dehusked or debittered dark malt.

What comes out is nearly all colour and very little bite. A brewer can add enough to turn the beer black and still keep the roast flavour down at a whisper of cocoa. That single choice is most of the answer to how this beer works.

The alternative brings astringency, which is the dry gripping feeling you get from strong tea or grape skins. A Schwarzbier should have none of it. If your tongue feels scrubbed, the brewer used too much roast or the wrong kind.

Decision two: keep everything else small

Under the dark malt is an ordinary German lager. The base is Pilsner and Munich malt at an everyday gravity, so the sweet liquid drained off the mash, which brewers call wort, is no richer than the one behind a Helles.

The beer is then fermented well out. Brewers call that attenuation, which just means how much of the sugar the yeast ate. Fermenting out is what keeps the body light and the finish dry, and it is why you can drink a half litre of something that looks like a stout.

So colour went up and nothing else did. Strength stayed at lager level, body went down rather than up, and the hops were left where a German lager normally puts them.

What it is not

2.4.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop.

Order one if you already like any of these

• The last mouthful of a black coffee that has gone cool. There is a trace of that here and no more.
• Plain dark chocolate, for the cocoa rather than the sugar. This beer gives you the cocoa without the sweetness.
• Rye crispbread, pumpernickel, or anything dry and dark. The finish is dry in exactly that way.
• Cold, clean, refreshing drinks. This is one, despite everything your eye is telling you.

Leave it for now if either of these is true

• You want a thick, sweet, filling dark beer. This one is deliberately thin, and you will feel short changed.
• You want hop smell. At 20 to 35 IBU the hops balance the roast and never step forward.

Ordering it

Take the full pour, and a half litre if the bar offers it. This is a 5% beer built to be drunk in quantity, and a small glass makes it look like a dessert beer, which it is not. It is also the best beer to hand somebody who says they cannot drink dark beer.

Five you can actually buy

2.4.2.2 Food, faults, and the black beer myth

The darkest beer in the module is one of the lightest, and that single fact does more work than anything else in this course.

Food

What does not work: very sweet puddings and rich chocolate desserts. The beer has no sugar to meet them with, so it ends up tasting thin and sour next to the plate.

What a good one does

Very dark brown and clear, with a tan head that holds. A faint smell of cocoa and coffee, and nothing burnt. Light and crisp in the mouth, then a short dry finish. You should be able to drink a half litre without ever thinking about it.

The faults this style suffers from most

A harsh, ashy edge is the common one. Two things give it away together. The roast tastes like a cigarette rather than cocoa, and your tongue feels dry and gripped afterwards. That means the brewer used too much roasted malt, or used the ordinary kind with the husk still on.

Hollowness is the opposite fault. Some examples take the lightness too far and give you a black beer with nothing in it. The mouthfeel should be light rather than empty, and mouthfeel is simply how a beer feels rather than how it tastes.

Then there is age. A slick butterscotch note is a fault called diacetyl, from a fermentation that was rushed or cut short. An old import tastes of wet cardboard with a dull sweetness behind it, and imported dark lager can sit on a shelf for a very long time.

2.7.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Bock is a strong dark lager with rich toasted malt and almost no hop character. The BJCP files it as Dunkles Bock, meaning dark bock, because a pale version exists too. Most bars and most labels just say Bock.

The physical tell

Hold the glass still and look at the head. A Bock carries a big creamy off white head that sits there for minutes rather than seconds, because there is a lot of malt underneath holding it up. Then swallow and count to three. A mild warmth spreads through your chest.

The head plus that delayed warmth is the field mark. Neither one is a flavour, which is why they are easier to trust than tasting notes.

Where it came from, and the goat

Einbeck is a town in Lower Saxony, in northern Germany. It was a Hanseatic League trading town, and from the fourteenth century onwards it exported strong beer in barrels across northern Europe. The beer had to survive the journey, so it was made strong.

Munich brewers recreated the style in the seventeenth century. Said in a Bavarian accent, the beer from Einbeck came out sounding like ein Bock. In German, ein Bock is a billy goat. The name stuck, and brewers have been putting goats on the labels ever since.

So the goat is a pun on a place name. It tells you nothing about the beer, and it is the single most useful thing to know when you are scanning a shelf, because the animal is easier to spot than the word.

2.7.1.2 More malt, longer boil, longer wait

There is no special ingredient here. There is a great deal more of the ordinary one, and a lot of patience.

Decision one: a large charge of Munich and Vienna malt, and nothing else

The sweet liquid drained off the mash is called wort, and how much sugar is in it decides how strong the beer can be. A Munich Helles starts near 1.048. A Bock starts at 1.064 to 1.072. That is roughly a third more grain again.

The grain is Munich and Vienna malt, sometimes with a very small amount of dark malt for colour. The BJCP is firm that no non malt additions belong here. There is no new ingredient anywhere in this beer, only more of the old ones.

Decision two: boil part of the mash, then wait for months

The traditional method is a decoction mash. The brewer scoops out part of the mixture of grain and hot water, boils it separately, and stirs it back in. The extra boiling browns the sugars, which is the same browning that gives bread its crust, and it is where the toast and the dark fruit come from.

Then the beer is stored cold for months, which is what lagering means. A big beer needs more of it than a small one. Those months are what turn a strong, rough young lager into something smooth enough to catch you out.

A beer this rich has to be fermented well out or it tastes like syrup. Brewers call that attenuation, which just means how much of the sugar the yeast ate. What stays behind are dextrins, long sugar chains the yeast cannot eat, and they are what give the beer its body without making it sweet.

Decision three: put the hops in early and leave them there

Hops go in at the start of the boil, where they give bitterness and lose their smell. Nothing is added late, because this style wants no hop aroma at all. The 20 to 27 IBU is there to stop the malt turning cloying, and for nothing else.

What it is not

2.7.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then a short and honest shopping list.

Order one if you already like any of these

• Toast with butter, or the browned top of a loaf. That flavour leads this beer.
• Malt loaf, fruit bread, or a slice of panettone. Bread with a little dried fruit behind it.
• The browned edge of a roast, or the sticky bit at the bottom of the pan.
• A drink you take slowly over an hour, the way people treat a glass of red wine.

Leave it for now if either of these is true

• You want hop smell or real bitterness. At 20 to 27 IBU the hops only stop the malt from cloying.
• You want a beer for a long evening. At 6.3% to 7.2% the second one is a decision rather than a habit.

Ordering it

Ask for a small pour. The German measure is 0.4 litres, and plenty of American bars serve strong lager at ten or twelve ounces for the same reason. A half litre of a 7% beer is roughly two and a half standard drinks, and it goes down easily.

Four you can actually buy

One national beer does carry the word: Shiner Bock, from Texas. It is 4.4% and retailers file it as an American amber lager. It is a pleasant beer and it is not this style, so do not use it to calibrate.

2.7.2.2 Food, faults, and what Bock does not mean

Two things everybody believes about this beer are wrong, and one of them will cost you money at a supermarket.

Food

What does not work: fresh salad, delicate white fish, and very hot chilli. The first two vanish underneath it. Chilli heat and alcohol together make the burn worse, and this is a strong beer.

What a good one does

Clear light copper to deep brown with a big creamy head that holds. Rich bread and toast on the nose, with a hint of dark fruit and nothing burnt. Smooth and medium full in the mouth, then a clean finish. The warmth should feel gentle rather than sharp.

The faults this style suffers from most

A syrupy, cloying finish is the common one. If the malt coats your teeth and you cannot face the second half of the glass, the yeast did not finish its work. Rich is correct here and sticky is not. The mouthfeel should be full and clean, and mouthfeel is simply how a beer feels rather than how it tastes.

Hot, solvent alcohol is the second. If it smells like nail polish remover or stings the back of your throat, the fermentation ran too warm or too fast, or the beer was not stored long enough. A well made Bock warms you and never bites.

Then there is age. A slick butterscotch note is a fault called diacetyl, from a fermentation that was rushed or cut short. An old seasonal bottle tastes of sherry and wet cardboard, and seasonal beers are exactly the ones that sit on shelves past their date.

2.9.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Doppelbock is a dark lager brewed to the strength of wine and built to be food. It was made to be swallowed instead of a meal, and that intention explains every number on this page.

The physical tell

Tilt the glass slowly and watch the inside wall. A beer this strong leaves slow sticky streaks that run back down, which a 5% lager will not do. Then swallow and wait three seconds. A soft warmth spreads through your chest. Streaks on the wall plus that delayed warmth is the field mark.

Where it came from

The monks of the Order of Minims, founded by Saint Francis of Paola, settled in the Au district of Munich and were brewing there by 1651. They made a strong beer each spring for their founder's feast day, which falls during Lent. Solid food was restricted during the fast. Liquid was not.

So they drank a beer thick with unfermented sugar and called it liquid bread. The nutritional part of that story holds up. Historians note that their version was fermented far less than a modern one, so it was rich in calories and lower in alcohol than what you buy today.

Why so many end in -ator

The monastery was secularised in 1799 and the brewery passed to Franz Xaver Zacherl, who named the beer Salvator, meaning saviour. Rival Munich brewers copied the name. Paulaner went to law and won the exclusive right to Salvator in the late nineteenth century.

Rivals could not use the word, so they invented their own names ending in the same three letters. Optimator, Celebrator, Triumphator, Maximator, Animator, Troegenator. Close to two hundred breweries now follow the pattern, which makes it the most useful naming tell on a beer shelf.

2.9.1.2 A very large mash, and a very long wait

This beer is made by putting far more grain in the kettle and then giving the yeast the time to deal with it.

Decision one: use far more malt

The sweet liquid drained off the mash is called wort, and the amount of sugar in it decides how strong the beer can be. A Munich Helles starts at about 1.048. A Doppelbock starts at 1.072 and can run past 1.100. That is roughly half as much grain again, or more.

The malt is mostly the same family used across this module: pilsner, Vienna and Munich malts, with a little dark malt for colour. There is no new ingredient here. There is just a great deal more of the old one.

Decision two: ferment it out, then wait

A beer this sweet at the start will taste like syrup unless the yeast eats most of the sugar. Brewers call that attenuation, which just means how much of the sugar was consumed. What is left behind are dextrins, which are long sugar chains the yeast cannot eat and which give the beer its thickness.

Then it is stored cold for months. That storing is what lagering means, and a big beer needs more of it than a small one. The months are what turn a strong, rough young beer into something smooth enough to be dangerous.

The traditional slow step

Decoction mashing is traditional here. The brewer scoops out part of the mixture of grain and hot water, boils it separately, and stirs it back in. The extra boiling browns the sugars, which is where the toast and the prune and raisin flavours come from. It is slow, and in this style many breweries still do it.

What it is not

2.9.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop.

Order one if you already like any of these

• Raisins, prunes, dates or malt loaf. Those dried fruit flavours are right at the front of this beer.
• Sticky toffee pudding, or the dark corner of a caramelised tray bake. Browned sugar without the burn.
• Dark rye bread and pumpernickel. This is the closest a drink gets to that flavour.
• A drink you sip slowly over an hour, the way people treat a glass of port or a whisky.

Leave it for now if either of these is true

• You want bitterness or hop smell. At 16 to 26 IBU there is almost none of either, and you will find it heavy going.
• You want a beer for a long evening. At 7% to 10% this is one glass, and the second one is a real decision.

Ordering it

Ask for a small pour. In Germany this comes in a 0.3 litre glass, and American bars often pour it at eight or ten ounces for the same reason. If a bar hands you a full pint of something at 8%, that is a large drink, and it is fine to say so.

Five you can actually buy

2.9.2.2 Food, faults, and what double does not mean

The name promises a doubling that never happens, and knowing what it really means will keep you out of one argument a year.

Food

What does not work: fresh salad, delicate fish, and very hot chilli. The first two vanish underneath it. Chilli heat and alcohol together make the burn worse, and this is the strongest beer in the module.

What a good one does

Clear deep brown with ruby glints and a big creamy head. Toasted malt and dried fruit on the nose, with no burnt note. Very full in the mouth, low in carbonation, and smooth all the way through. The warmth should feel gentle rather than sharp.

The faults this style suffers from most

Hot, solvent alcohol is the first. If the beer smells like nail polish remover or burns the back of your throat, it was fermented too warm or too fast. A well made Doppelbock warms you without ever stinging, and the difference is obvious once you have met both.

A cloying, sticky finish is the second. Rich is correct and syrupy is not. If it coats your teeth and you cannot face a second mouthful, the yeast did not finish its work. The mouthfeel should be full and smooth, and mouthfeel is simply how a beer feels rather than how it tastes.

A slick butterscotch flavour is a fault called diacetyl, from a fermentation that was rushed or cut short. It is less common here than in a pale lager, because there is a great deal more flavour in the way.

2.11.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

A Baltic Porter is a strong dark beer from the countries around the Baltic Sea, and almost every one of them is fermented with lager yeast. The word porter on the label describes where the recipe came from. It does not describe how the beer was made.

The physical tell

Tilt the glass hard against a strong light and look at the thin edge. A red or copper line shows there. An Imperial Stout of the same strength gives you nothing, because it is genuinely black. That red edge is the fastest way to tell the two apart before you taste anything.

The second tell is what your mouth does not report. This beer can be 9% and it will not burn, sting or taste hot. Full body, real warmth, and no sharpness anywhere. If a strong dark beer feels this smooth, you are probably holding a lager.

Where it came from

English brewers shipped porter around the Baltic through the eighteenth century, and it sold well in the courts and ports of the region. Those imports dried up in the early 1800s. Local brewers set about making their own version instead.

They had cold cellars and they had lager yeast, so that is what they used. The recipe stayed English and the fermentation went local. Over time the beers got stronger, and Poland, Finland, Estonia, Latvia, Lithuania, Sweden and Denmark each ended up with their own reading of it.

The name is new. Brewers and drinkers only started calling this family Baltic Porter in the 1990s, when writers needed one label for a group of beers that had grown up separately. The beers are two centuries old and the style name is about thirty.

2.11.1.2 Cold yeast on a warm recipe

Two decisions turn an English recipe into something that can be 9% and still taste gentle.

Decision one: ferment it cold, with lager yeast

Ale yeast works warm and throws off fruity flavours as it goes, which is why English ales taste of pear, apple or banana. Lager yeast works cold and makes almost none of that. Nothing stands between you and the malt.

Then the beer is stored cold for months, which is what lagering means. Time smooths out the harsh compounds that a strong fermentation leaves behind. That is why a 9% Baltic Porter does not sting, and it is the whole reason the style feels so much gentler than it measures.

There are exceptions and it is worth being honest about them. A few Baltic breweries use ale yeast, and the BJCP notes that when they do, they still ferment it cold. Russian versions historically had to use ale yeast for regulatory reasons. Cold is the constant, not the yeast species.

Decision two: a very big mash, with the dark malt kept gentle

The sweet liquid drained off the mash is called wort, and its sugar content sets the ceiling on strength. A Baltic Porter starts at 1.060 to 1.090, which is a great deal of grain. The base is usually Munich or Vienna malt, so there is toast and caramel under everything else.

The dark malt is usually the dehusked kind, with the papery outer skin stripped off before roasting. That gives chocolate and molasses instead of char. It is the same choice that makes a Schwarzbier work, applied to a beer four percent stronger.

The beer still ferments well out. Brewers call that attenuation, which just means how much of the sugar the yeast ate. What stays behind are dextrins, long sugar chains yeast cannot eat, and they give the beer its full body without turning it sticky.

What it is not

2.11.2.1 Will you like it, how to ask, what to buy

Predicting your own reaction from food you already eat, then five you can find in an American shop.

Order one if you already like any of these

• Prunes, figs, raisins and dates. Dried fruit is right at the front of this beer.
• Treacle, molasses or dark muscovado sugar. Deep sweetness without a burnt edge.
• Dark chocolate, and liquorice if you are one of the people who likes it.
• A drink you sip slowly over an hour, the way people treat a glass of port.

Leave it for now if either of these is true

• You want the sharp burnt coffee bite of a stout. This beer deliberately stops short of it.
• You want a beer for a long evening. At 6.5% to 9.5% this is one glass, and the second is a decision.

Ordering it

Ask for a small pour. Most bars serve this in eight or ten ounces, and a snifter is the usual glass. If somebody hands you a pint of something at 9%, that is a large drink, and it is entirely fine to say so and ask for less.

Five you can actually buy

2.11.2.2 Food, faults, and the word porter

The name on the bottle points at the wrong half of the beer, and once you see that the whole style makes sense.

Food

What does not work: fresh salad, delicate white fish and very hot chilli. The first two disappear underneath it. Chilli heat and alcohol together make the burn worse, and this is the strongest beer in the module.

What a good one does

Very dark reddish brown with a red edge against a light, under a thick tan head. Caramel, toffee and dried fruit on the nose, with no burnt note. Full and rounded in the mouth with lively carbonation, then a finish drier than the start. The warmth should feel gentle.

The faults this style suffers from most

Hot, solvent alcohol is the first. If it smells of nail polish remover or stings your throat, the fermentation ran too warm or the beer was not stored long enough. A well made Baltic Porter carries 9% without any sharpness at all, and the difference is obvious once you have met both.

A sticky, cloying finish is the second. Full is correct and syrupy is not. If it coats your teeth and you cannot face a second mouthful, the yeast did not finish. The mouthfeel should be full and smooth, and mouthfeel is simply how a beer feels rather than how it tastes.

Oxidation is the interesting one. In most beers a sherry or wet cardboard note is a plain fault, and a slick butterscotch note is a fault called diacetyl. In this style the Brewers Association says a low level of oxidation is acceptable when it sits in harmony with everything else. A trace of dried fruit sherry is part of the tradition, and wet cardboard never is.

2.12.1.1 The specimen plate

Field marks first. Everything else in this style builds on this page.

Rauch is German for smoke. A Rauchbier is an ordinary amber Bavarian lager made with malt that was dried over a beechwood fire, so the smoke went into the grain before the brewing ever started. Everything else about the beer is completely conventional.

The physical tell

You will smell it before you touch it. Set the glass down at arm's length and the smoke still reaches you, which almost no other beer manages. That alone identifies the style across a table.

The second tell comes after you swallow. The beer leaves and the smoke stays, sitting in your mouth for a good while longer. Notice whether it tastes like food or like an ashtray, because that is also how you judge whether it was made well.

Where it came from

Every beer used to taste like this. Malt has to be dried before it can be brewed, and for most of history that meant drying it over a fire. The smoke went into the grain whether the brewer wanted it there or not. Smoky beer was not a style. It was beer.

Kilns that keep the smoke away from the grain spread through the seventeenth and eighteenth centuries. British brewers dropped the flavour first, and German brewers had largely followed by about 1800. Within a few generations, most drinkers had never tasted it.

Bamberg, in Franconia, kept it. Two explanations get offered: the enormous beech forests around the town, and a conservative city governed by the church until the early 1800s. Both are plausible and neither is proven, so treat the survival as a local habit that simply never broke.

Two Bamberg breweries carry the tradition today. Schlenkerla is the famous one, and its odd name comes from a Franconian nickname for a man who walked with a swinging gait. Spezial is the quieter one, dating to 1536, and it makes a gentler beer.

2.12.1.2 The fire is under the malt, not under the beer

The whole style is decided at the maltings, before the brewer has done anything at all.

Decision one: dry the malt over an open beechwood fire

Barley has to be steeped, sprouted and then dried before it can be brewed. At Schlenkerla that last step happens in a kiln with a beechwood fire burning underneath it, so smoke passes through the wet grain for roughly a day. The flavour goes into the barley and stays there.

The compounds responsible are phenolic, which means they belong to the same chemical family that flavours smoked ham and smoked fish. That is why the beer smells like food rather than like burnt toast. Beech gives a rounder, meatier smoke than oak or alder do.

Nothing is added to the beer itself. No smoke goes into the kettle, no flavouring goes into the tank. If a brewer tells you they smoked the beer, they mean they smoked the grain.

Decision two: brew a completely ordinary Marzen around it

Everything after the maltings is normal. The same mash, often with the traditional decoction step where part of the grain and water mixture is boiled separately and stirred back in. The sweet liquid drained off, which brewers call wort, is boiled with ordinary German hops.

Then it is fermented cold with lager yeast and stored cold for weeks. Take the smoke out and you would have a competent amber Bavarian lager and nothing more. That is the point: this is not an experimental beer, it is a conventional one made with one unusual ingredient.

The dial: how much smoked malt

The one thing a brewer controls is the proportion. Schlenkerla builds its Marzen from close to all smoked malt, which is why it hits so hard. Spezial uses around 40 percent and lands somewhere much gentler. Same town, same wood, very different beers.

That range matters when somebody tells you they hate Rauchbier. There is a fair chance they met the strongest version in the world on their first attempt.

What it is not

2.12.2.1 Will you like it, how to ask, what to buy

This is the one style in the course where the honest answer is that a lot of people will not, and that is fine.

The honest version, first

Plenty of people take one mouthful of Schlenkerla and put the glass down. That is a normal reaction to a beer built almost entirely from smoked malt. It is not a failure of taste and there is nothing to work through if you do not want to.

There is an old Bamberg line that you need three glasses before you can judge it, because the first is the hardest. That is probably true and it is also a litre and a half of beer. Share a bottle with somebody instead, and drink it with food rather than on its own.

Order one if you already like any of these

• Smoked ham, bacon, or a good frankfurter. That is very close to what this beer smells of.
• Barbecue where you can smell the wood before you see the food.
• Smoked cheese, smoked almonds, or lapsang souchong tea.
• Islay whisky, if you have had one and enjoyed it. Different smoke, and the same willingness.

Skip it if either of these is true

• You dislike smoked food. There is no gentle route into this and no version that hides the smoke.
• You dislike the smell of a bonfire on your coat the next morning. That smell is the beer.

Ordering it

Ask for a taste first. Any bar that stocks this beer expects the question and will not think twice about it. Then ask which one, because the smoke level is not the same across the range.

Five you can actually buy

2.12.2.2 Food, faults, and the oldest flavour in the room

This beer is not a modern experiment. It is what everybody used to drink, and the rest of the world is the thing that changed.

Food

What does not work: delicate white fish, fresh salad, and almost any dessert. This beer buries subtlety, and next to sugar the smoke turns strange and ashy.

What a good one does

Clear deep amber to coppery brown with a large creamy tan head. Smoke that smells like smoked ham rather than like an ashtray, with real toasted malt underneath it. Medium bodied and smooth, then a medium dry finish. You should want another mouthful straight away.

The faults this style suffers from most

Acrid, ashy smoke is the first. The BJCP is explicit that harsh or burnt smoke is wrong here. Good smoke reads as food. Bad smoke reads as a cold fireplace, and it usually arrives with a scratchy feeling at the back of the throat.

No smoke at all is the second, and it is more common than you would think. Smoke fades on the shelf. If a Schlenkerla tastes like a slightly dull Marzen, the bottle is old rather than badly made.

A plastic or medicinal note is the third. Smoke flavours are phenolic, which means they belong to the chemical family that also produces sticking plaster and disinfectant smells when a fermentation goes wrong. Savoury and meaty is correct. Medicinal is not.

Then there are the ordinary lager faults, which the smoke can hide for a mouthful and no longer. A slick butterscotch flavour is diacetyl, from a fermentation that was rushed or cut short. The mouthfeel should stay clean and medium, and mouthfeel is simply how a beer feels rather than how it tastes.

2.C.1 The rest of the amber and dark lagers

A lookup page. Four cards side by side, then twelve lines each.

Nobody is expected to memorise this screen. It is here so that a name on a menu stops being a blank. Read the four cards together first, because each one makes more sense next to the other three, then drop down to whichever style you are actually holding.

Czech Amber Lager

• What it is, deep amber to copper and bright, under a thick off-white head that is still there when the glass is empty. The tell is texture. It feels soft and round in your mouth rather than crisp, and the bubbles are gentle.
• Where it is from, the Czech lands. Czech beer is sorted by colour, and this is the middle class, polotmave, meaning half dark. It faded through the twentieth century and small Czech breweries have been rebuilding it since.
• Why it tastes that way, the brewer blends Czech caramel malt into a pale malt base, then runs a decoction mash. That means part of the mash is lifted out, boiled, and stirred back in. The boiling is where the toast and the caramel come from.
• Confused with, Vienna Lager at 2.1, which is leaner and toastier with far less hop spice. Marzen at 2.2, which is stronger and rounder, with German hops rather than Czech Saaz. Czech Dark Lager, which goes past caramel into chocolate.
• Numbers, 4.4% to 5.8% ABV, 20 to 35 IBU, 10 to 16 SRM. The Brewers Association allows one shade more colour, at 10 to 17 SRM. Serve it at 45F to 50F, which is 7C to 10C.
• You will probably, enjoy it and then struggle to describe it. It is caramel without sweetness and bitterness without bite. If you want a beer that argues with you, this is not that beer.
• Ordering it, say "do you have the polotmave". Czech puts the stress on the first syllable, so PO-lo-tma-ve. In an American bar, "the Czech amber lager" gets you there.
• Eat with, roast pork, or a plain burger. Caramel malt against browned meat is one of the few pairings that works by matching rather than by cutting.
• Is it any good, yes, and it is genuinely hard to find. Outside the Czech Republic you meet it at breweries that have decided to specialise in lager, and almost nowhere else.
• Try this one, the Czech-Style Amber Lager from Eckhart Beer Co in Bushwick, Brooklyn, at 5.4%. It is canned, poured at their taproom, and sold online by Half Time Beverage. Imported Czech examples barely reach American shelves at all.
• The myth, that a half dark beer is a pale beer and a dark beer mixed in the glass. That mix is real and Czech pubs sell it as rezane, or cut beer. A polotmave is one beer, brewed amber from the start.
• Remember, half dark, not half and half.

Czech Dark Lager

• What it is, black across a room, garnet at the edges when you hold it to a light, under a tan head that lasts. The tell is weight. It is much lighter in your mouth than its colour promises, and it leaves no coating behind.
• Where it is from, the Czech lands. The best known version is poured at U Fleku in Prague, which has been brewing on the same site since 1499.
• Why it tastes that way, the brewer builds the colour with dark caramel malt and debittered roasted malt, which is roasted grain with the harsh husk character stripped out. Chocolate, toast and cola arrive, and the coffee bitterness does not.
• Confused with, Munich Dunkel at 2.3, which is bready and soft with no chocolate. Schwarzbier at 2.4, which is drier and thinner with a sharper roasted edge. Irish Stout at 6.3, which is an ale, far more bitter, and dry at the finish.
• Numbers, 4.4% to 5.8% ABV, 18 to 34 IBU, 17 to 35 SRM. The two guideline sets disagree about the colour and the panel on the next screen shows both. Serve it at 45F to 50F, which is 7C to 10C.
• You will probably, like it more than you expect. It reads as chocolate and toast at ordinary lager strength. If you came looking for roasted bitterness you will find it too polite.
• Ordering it, say "the tmave, please", which sounds like TMAH-veh, or ask for "the dark Czech lager". If a Czech pub offers to cut it with the pale one, that is rezane and it is worth trying once.
• Eat with, roast duck, or goulash. It also handles gingerbread and anything with cinnamon in it, which very few beers manage.
• Is it any good, yes, and it is one of the best value beers in this module. Be aware that exported versions are often weaker and sweeter than what is poured in Prague.
• Try this one, Czechvar Dark from Budweiser Budvar, at 4.7%, whose American importer changed hands in early 2026, so ask rather than assume. Kozel Cerny, at 3.8% in 500 millilitre cans, is easier to find and is weaker than the guideline floor.
• The myth, that Czech beer means pale Pilsner, so a dark Czech beer must be a novelty or an import. Czech brewing has sorted beer by colour for centuries. U Fleku has been brewing dark beer on one Prague site since 1499, which is three and a half centuries before Pilsner was invented.
• Remember, tmave is a colour word, not a strength word.

Helles Bock and Maibock

• What it is, deep gold to light amber under a thick creamy white head. The tell arrives late. A few seconds after you swallow there is a warmth in your chest, from a beer that tasted like an ordinary golden lager on the way down.
• Where it is from, Germany. Strong beer reached Munich from the town of Einbeck, and the Hofbrauhaus dates its Maibock to 1614 and to a brewer called Elias Pichler. The pale spring version as a defined type is a good deal more recent than that.
• Why it tastes that way, the brewer builds a bock out of pale Pilsner and Vienna malt instead of dark Munich malt, then hops it harder than any other bock. That extra bitterness is what stops a 7% beer from finishing sticky.
• Confused with, Bock at 2.7, which is dark brown, sweeter and less bitter. Doppelbock at 2.9, which is stronger again and much richer. Festbier at 1.8, which is the same gold and more than a percent weaker.
• Numbers, 6.3% to 7.4% ABV, 23 to 35 IBU, 6 to 9 SRM. The Brewers Association runs wider on all three, and the next screen shows both. Serve it at 45F to 50F, which is 7C to 10C.
• You will probably, be surprised by how easy it is to drink. That is the risk as well as the pleasure, because it goes down like a 5% beer and is not one.
• Ordering it, say "is the Maibock fresh". It is a spring beer, and a bottle that has sat on a shelf until August is a different drink. A half is a sensible pour.
• Eat with, roast chicken, ham, or asparagus, which is what Germany is eating when this beer appears. Aged gouda works as well.
• Is it any good, yes, and it is the friendliest strong lager there is. Its weakness is that a dull one tastes like a large Munich Helles and nothing more.
• Try this one, Hofbrau Maibock, at 7.2%, in 11.2 ounce bottles and on draft from the middle of February to the end of April. Ayinger Maibock arrives in the same window and is sold in four packs by the larger American chains.
• The myth, that Helles Bock and Maibock are two different styles. Both guideline sets treat them as one beer with two names, and the Brewers Association prints its entry as German-Style Heller Bock and Maibock together.
• Remember, a bock that stayed pale, and got hopped to stay dry.

Eisbock

• What it is, deep copper to dark brown with ruby at the edge, under a head that gives up early. Tilt the glass and thick legs run back down the inside, the way they do in a strong wine. The carbonation is low and the warmth is obvious.
• Where it is from, Kulmbach in Franconia, in northern Bavaria, in the late 1800s. The story told there is that barrels were left out in winter and froze, and what came out of the middle was far stronger than what went in.
• Why it tastes that way, the brewer freezes a Doppelbock and takes the ice out. Water freezes and alcohol does not, so everything left behind is concentrated. Nothing is heated and nothing is boiled off, which is why this is not distilling.
• Confused with, Doppelbock at 2.9, which is the same beer before the ice and much less warming. Baltic Porter at 2.11, which reaches a similar strength with roasted malt instead of freezing. Some Doppelbocks are stronger than some Eisbocks, so the number alone will not settle it.
• Numbers, 9% to 14% ABV, 25 to 35 IBU, 17 to 30 SRM. Real bottles run from about 7% to well past 30%, and the guidelines do not agree, so read the label. Serve it at 50F to 55F, which is 10C to 13C.
• You will probably, either love it or find it far too much. If port, sherry or a dark rum appeal to you, this is the beer that behaves like them.
• Ordering it, say "the smallest pour you do, please". Anything more than a third of a pint is a mistake with a first Eisbock, and most bars that stock one already know that.
• Eat with, blue cheese, or dark chocolate, or nothing at all. This is a beer for the end of an evening rather than for a meal.
• Is it any good, at its best it is one of the great beers, smooth and warming and deep. It is also the style most often ruined, because concentrating a beer concentrates its faults with everything else.
• Try this one, Kulmbacher Eisbock, at 9.2%, in 330 millilitre bottles from online American beer shops. Schneider Aventinus Weizen-Eisbock, at 12%, is easier to find and is a frozen wheat beer, which the guidelines file somewhere else.
• The myth, that Eisbock is a stunt for people chasing the strongest beer in the world. The Kulmbach original is a winter beer at about 9%. The record chase is a separate business, and a 2020 collaboration between Schorschbrau and BrewDog reached 57.8%.
• Remember, the ice is water, and what is left is still beer.
