Module 10, Historical and regional beers

Beers that predate modern brewing, or survive in one valley. You will rarely meet them. They explain a great deal about the rest.

Printable version. Every question is shown with its answer.

Class 10.C

Historical and regional beers

Six beers you will rarely see. Each one kept a decision that modern brewing dropped, so together they show what beer looked like before it was standardised. Meeting one on a menu is a small event, and the only thing you need is to recognise the name.

By the end of this class you will be able to

  1. Recognise all six names on a menu and say roughly what each one is
  2. Name the single decision that separates each of them from a modern beer
  3. Explain why kveik is a yeast rather than a style, and why that matters in a bar in 2026
  4. Know which of these you can actually buy, and what to drink instead when you cannot
  5. Correct the two most repeated wrong facts in this group: the sour mash and the gin flavour

10.C.1 The six, side by side

A reference screen. Six cards first, 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 six cards together first, because each one is easier to hold when it has neighbours to sit next to. Then come back to whichever line you need.

Sahti

Finnish, farm brewed, and nearly still. Filtered through juniper branches instead of a filter bed, and fermented with baking yeast, which is where the banana and clove come from. Strong, sweet and thick. Almost no hops.

Norwegian Farmhouse and Kveik

Kveik is a family of Norwegian farm yeasts, not a beer. It ferments hot and fast without the harsh flavours that would normally cause, which is why it now turns up in ordinary craft beer. The word on a can describes the fermentation, not the recipe.

Roggenbier

A dark German wheat beer with the wheat swapped for rye. Up to 60 percent malted rye gives black pepper and a fuller body, and the wheat beer yeast keeps the banana and clove underneath it.

Sahti

  • What it is, almost no hiss when it is poured and no bubbles rising in the glass. It is cloudy, it feels thick, and it coats the glass as you tilt it. The smell of banana arrives before you get close.
  • Where it is from, Finland, brewed on farms for at least five hundred years and still made in Finnish villages today.
  • Why it tastes that way, three decisions. The brewer runs the mash through a trough packed with juniper branches instead of a filter bed. The wort, which is the sweet liquid that becomes beer, is never boiled. And the fermentation uses Finnish baking yeast, which is what makes the banana and the clove.
  • Confused with, Weizenbock, taught at 4.3, which gets the same banana and clove from a wheat beer yeast and is boiled, hopped and fizzy. Roggenbier, below, which shares the rye and the banana and is about half the strength with real hops in it.
  • Numbers, 7% to 11% ABV, 0 to 15 IBU, and SRM 4 to 22, so yellow through dark brown. The two rulebooks disagree about the bitterness, which is covered on the next screen.
  • You will probably, find it strange for two mouthfuls and then interesting. It is sweet, heavy and warming with no bitterness to cut it, so if you dislike sweet drinks you will not finish a large glass.
  • Ordering it, a small pour of the sahti, please. Said SAH tee. Ask for a small one and mean it, because this is a beer that starts at 7%.
  • Eat with, salted or cured fish, and rye bread. That is the Finnish answer and it works, because salt is the only thing that gets through the sweetness.
  • Is it any good, genuinely unusual and worth one glass. It is also sweet, strong and flat, which is three things most drinkers do not want at once. Divisive, and honestly so.
  • Try this one, you will almost certainly not find a sahti. Finnish producers barely export, so the nearest thing you can buy is Schneider Weisse Tap 6 Unser Aventinus at 8.2%, a Weizenbock sold year round across the United States. Same banana and clove, same strength, none of the juniper.
  • The myth, people say the juniper makes it taste of gin. The juniper goes in as branches and wood rather than berries, so it reads as pine and resin. The banana is the baking yeast, not the tree.
  • Remember, juniper for a filter, baking yeast for the banana, and no hops at all.

Norwegian Farmhouse and Kveik

  • What it is, this one has no look of its own, because kveik is a yeast. The tell is printed on the can. Where you do meet a traditional Norwegian farmhouse ale it is hazy, soft, low in bubbles and smells of orange and tropical fruit.
  • Where it is from, the farms of western Norway, where families kept their own yeast alive for generations by drying it on a wooden ring between brews. Lars Marius Garshol began documenting and sharing these yeasts from about 2013.
  • Why it tastes that way, farmers pitched their yeast into hot liquid and reused it for decades. That selected for strains which work at 86F to 104F, meaning 30C to 40C. They finish in one to three days, and they do not throw the harsh solvent flavours an ordinary yeast produces at that heat.
  • Confused with, Sahti, above, which is Finnish and filtered through juniper, where Norwegian farmhouse ale is more often steeped with juniper and fermented with kveik. Hazy IPA, which is where most Americans actually meet kveik, and which is a hop decision rather than a yeast one.
  • Numbers, there is no official range, because a yeast is not a style. American beers that advertise kveik run roughly 5% to 9% ABV at any bitterness and any colour. The numbers that matter belong to the yeast: 86F to 104F, and done in one to three days.
  • You will probably, have drunk it already without knowing. Order one if you like mango and pineapple flavours in a drink and you do not mind a hazy glass.
  • Ordering it, is anything on here fermented with kveik. Most English speakers say KVIKE, to rhyme with bike.
  • Eat with, whatever suits the beer it is hiding inside. In its traditional Norwegian form, cured meat and a strong hard cheese.
  • Is it any good, the yeast is genuinely useful and that is why it is worth knowing. Beers labelled kveik vary enormously, because the label tells you about the fermentation and nothing about the recipe.
  • Try this one, there is no dependable bottle. Kveik beers are usually one off releases and they vanish fast, and two of the best known ones have already come off their breweries lineups. Read the can instead. The words kveik, Voss, Hornindal and Lutra all mean this yeast, and a hazy IPA is the likeliest place to find it.
  • The myth, people call kveik a beer style. It is a yeast. Garshol makes the point that Norway has several separate farmhouse traditions. Calling them one national style would be like treating smoked beer, barley wine and Berliner Weisse as the same thing.
  • Remember, kveik is a who, not a what. It names the yeast, never the beer.

Grodziskie

  • What it is, pale gold and bright, under a tall white head that refuses to sink. The carbonation prickles on the tongue, close to sparkling wine. The smell is wood smoke.
  • Where it is from, Grodzisk Wielkopolski in western Poland. Malting there is recorded from 1426, and the beer as we know it settled into shape by the early twentieth century.
  • Why it tastes that way, one decision above all others. The grain is oak smoked wheat malt and nothing else. A second decision finishes it: the beer is carbonated far harder than a normal beer, which lifts the smoke out of the glass.
  • Confused with, Berliner Weisse, taught at 8.1, which is the same tiny strength and is sour where this one is bitter. Rauchbier, which is a stronger, maltier lager carrying much heavier smoke.
  • Numbers, 2.5% to 3.3% ABV, 20 to 35 IBU, SRM 3 to 6. The American rulebook puts it noticeably stronger, which is covered on the next screen.
  • You will probably, enjoy it more than you expect. Smoke on a beer this light reads as bacon or a campfire rather than as an ashtray, and there is no weight behind it to make it tiring.
  • Ordering it, a Grodziskie, please. How smoky is yours. Said roughly grod ZEES kyeh, and nobody will mind if you point at it.
  • Eat with, smoked fish, sausage, or a board of hard cheese. Smoke sits well beside smoke, and the carbonation clears the fat between mouthfuls.
  • Is it any good, yes, and it is the easiest of these six to like. Low alcohol, loud flavour and a clean dry finish is a rare combination.
  • Try this one, Live Oak Grodziskie at 3.0% and 36 IBU, brewed in Austin and sold year round in cans and on draft, though the brewery distributes mainly inside Texas. In Poland, Browar Grodzisk makes it again in the original brewery building.
  • The myth, people assume that a style which died stays dead. Commercial production stopped in the 1990s, Polish homebrewers rebuilt the recipe, the first new commercial version arrived in 2010, and the original brewery reopened in 2015.
  • Remember, Polish, smoky, tiny and fizzy. The beer that came back.

Kentucky Common

  • What it is, amber to brown and usually clear, under a beige head that collapses faster than you expect from a dark beer. It feels light and highly carbonated in the mouth, and it finishes dry.
  • Where it is from, Louisville, Kentucky, from after the Civil War until Prohibition. BJCP puts it at about 75 percent of the beer sold around the city at its peak.
  • Why it tastes that way, the brewer used corn grits alongside six row barley with a small amount of caramel and black malt for colour. Then fermented warm and sold the beer inside about a week, because Louisville could not cut enough winter ice to store beer cold.
  • Confused with, Cream Ale, which is the same idea left pale. American Brown Ale, taught in Module 5, which is maltier, fuller and far less fizzy.
  • Numbers, 4% to 5.5% ABV, 15 to 30 IBU, SRM 11 to 20. Both rulebooks agree on all three, which is unusual in this group.
  • You will probably, find it easy and slightly plain. The interesting part is the trick it plays: it looks like a dark beer and behaves like a light one.
  • Ordering it, a Kentucky Common, please, and is it sour. Worth asking, because modern versions vary on exactly that point.
  • Eat with, fried chicken, burgers, barbecue. It was a cheap beer served with cheap food, and the dry fizzy finish scrubs grease well.
  • Is it any good, pleasant rather than exciting. Most of its value is historical, and it is a good beer to drink while somebody explains why it exists.
  • Try this one, nothing packaged travels. It lives in Louisville taprooms, where Apocalypse Brew Works pours Oertel's 1912 at 4.7% and Falls City makes a Kentucky Common at 4.0%. Far from Louisville, Yuengling Traditional Lager at 4.5% is the nearest supermarket stand in: amber, corn in the grist, gently bitter, and a lager rather than an ale.
  • The myth, nearly everything written about this beer says it was sour mashed. BJCP 2021 says brewing records from around 1900 show no sour mashing, no long acid rests and no extended ageing, and calls the sourness a likely modern invention.
  • Remember, Louisville's cheap dark ale, drunk within a week because there was no ice.

Pre-Prohibition Lager

  • What it is, deep gold and bright, under a thick white head that lasts. It feels creamier and fuller in the mouth than a modern pale lager, and the bitterness stays with you after you swallow.
  • Where it is from, the United States. German immigrant brewers rebuilt their lagers around American grain from the mid 1800s, and the style was at its height around the 1870s.
  • Why it tastes that way, two decisions. Corn or rice went in at up to 30 percent alongside six row barley, because six row carries too much protein to make a clean pale lager on its own. And the brewer hopped it hard, with American and Continental hops rather than modern citrus varieties.
  • Confused with, American Lager, which is the same beer after a century of thinning out: 8 to 18 IBU there against 25 to 40 here. German Pils, which is just as bitter and is all barley, drier and sharper.
  • Numbers, 4.5% to 6% ABV, 25 to 40 IBU, SRM 3 to 6. The American rulebook has no entry for it at all.
  • You will probably, recognise it and then be surprised by it. It tastes like a familiar American lager with the volume turned up, which is a more interesting experience than it sounds.
  • Ordering it, is that the pre-Prohibition one, and how bitter is it. The second half of that question is the one that matters.
  • Eat with, fried food, sausages and sharp cheddar. The bitterness holds up to salt in a way a modern light lager cannot.
  • Is it any good, yes, and it is the most useful beer on this screen. It is the only way to taste what the most drunk beer in America used to be.
  • Try this one, Capital Supper Club at 5.0% and 28 IBU, brewed in Middleton, Wisconsin with corn flakes in the grain bill and sold year round. Schell Deer Brand at 4.7% is easier to find across the upper Midwest, and the brewery calls it a pre-Prohibition lager. At 18 IBU it is gentler than the guideline asks for. Check the BJCP example list against the brewery before you go looking, because some of those beers have come off their lineups.
  • The myth, people say corn in beer is a modern cost cutting trick. Corn was in American lager from the beginning, and it was there for a technical reason. Six row barley carries too much protein for an all barley pale lager to come out clean.
  • Remember, the American lager from before it lost its hops.

Roggenbier

  • What it is, dark reddish brown and hazy, under a thick tan head that sits there and does not move. It feels fuller in the mouth than the colour prepares you for, and it smells of black pepper and banana at the same time.
  • Where it is from, Bavaria, and it is modern rather than ancient. BJCP dates the style to Schierlinger Roggen, brewed near Regensburg in 1988.
  • Why it tastes that way, two decisions. Up to 60 percent of the grain is malted rye, which gives the pepper and the body. Then the brewer ferments it with a wheat beer yeast, which puts banana and clove underneath the pepper.
  • Confused with, Dunkles Weissbier, which is the same beer with wheat instead of rye and none of the pepper. Rye IPA, met inside Module 3, which has the rye but swaps the yeast for a clean one and buries everything under American hops.
  • Numbers, 4.5% to 6% ABV, 10 to 20 IBU, SRM 14 to 19. The American rulebook files it as German-Style Rye Ale, asks for at least 50 percent rye and sets bitterness at 10 to 15 IBU.
  • You will probably, like it if you already like Hefeweizen and have ever wished it had more grip. If banana in beer is not for you, this will not convert you.
  • Ordering it, a Roggenbier, please. Said ROG en beer, with a hard g. Ask for it in the tall wheat beer glass if there is one.
  • Eat with, cured sausage and mustard, dark bread, or an aged hard cheese. The peppery rye lines up with the mustard instead of fighting it.
  • Is it any good, yes, and it is rarer than it deserves to be. Rye does something to body and to spice that no other grain does, and this is the clearest place to taste it on its own.
  • Try this one, Reuben's Brews in Seattle makes a Roggenbier at 5.3% and 19 IBU, taproom only, so treat it as a reason to visit rather than a plan. In Germany, Schierlinger Roggen is still made. The example BJCP names, Thurn und Taxis Roggen, is retired, so do not go looking for it.
  • The myth, people assume the peppery flavour is a spice somebody added. It is the grain. BJCP says outright that adding caraway seeds, as some American brewers do, is wrong for the style.
  • Remember, take a dark wheat beer, swap the wheat for rye, and pepper appears.

Check yourself

  1. Somebody hands you a cloudy amber beer that made no hiss when it was poured, feels thick, and smells strongly of banana. Which of these six is it?
    Answer: Sahti
    Sahti. It is nearly still, it is thick because the liquid is never boiled, and the banana comes from Finnish baking yeast. Grodziskie is the tempting answer for anything unfamiliar, and it is the opposite in every way: pale, bright, and carbonated hard enough to prickle.
  2. Both of these smell of banana and clove. Sort each fact into the beer it belongs to.
    Answer: The liquid is never boiled goes in Sahti · Juniper branches do the filtering goes in Sahti · Fermented with Finnish baking yeast goes in Sahti · 7% to 11% alcohol goes in Sahti · Up to 60 percent malted rye goes in Roggenbier · Fermented with a German wheat beer yeast goes in Roggenbier · 10 to 20 IBU of genuine hop bitterness goes in Roggenbier · Bavarian, and first brewed in 1988 goes in Roggenbier
    The banana and clove are the trap, because two completely different yeasts arrive at the same pair of flavours. Everything else separates them. Sahti is unboiled, unhopped and twice the strength, and Roggenbier is a normal German brewery beer with rye in place of wheat.
  3. Kveik is the name of a Norwegian beer style.
    Answer: False
    False. Kveik is a family of Norwegian farmhouse yeasts, kept alive on farms for generations. The word is tempting because it appears on beer cans, where it describes the fermentation and tells you nothing about the recipe. Lars Marius Garshol, who documented these yeasts, notes that Norway has several separate farmhouse traditions rather than one style.
  4. What makes kveik unusual as a brewing yeast?
    Answer: It ferments at 86F to 104F, which is 30C to 40C, and finishes in one to three days
    Hot and fast, and without the harsh solvent flavours an ordinary yeast throws at that temperature. That combination is why kveik moved out of Norwegian farmhouses and into ordinary craft breweries, since it frees up a fermentation tank in days rather than weeks. The cold slow option describes lager brewing, which is the opposite end of the scale.
  5. Grodziskie is named after the town it came from. Which country is that town in?
    Answer: poland
    Poland. The town is Grodzisk Wielkopolski in the west of the country, where malting is recorded from 1426. Germany is the tempting answer, partly because the town was called Gratz under German rule and partly because smoked beer is usually a German thing.
  6. Both of these are pale and clearly bitter. Sort each fact into the beer it belongs to.
    Answer: Made entirely from oak smoked wheat malt goes in Grodziskie · About 3 percent alcohol goes in Grodziskie · Polish, and brewed again in its original brewery from 2015 goes in Grodziskie · Corn or rice at up to 30 percent of the grain goes in Pre-Prohibition Lager · About 5 percent alcohol goes in Pre-Prohibition Lager · American, and at its height around the 1870s goes in Pre-Prohibition Lager
    Colour and bitterness will not separate these two, because both sit at SRM 3 to 6 and both land in the twenties and thirties for IBU. Strength and grain do separate them. One is a smoked wheat beer at 3 percent, the other is a corn lager at 5 percent, and the smoke is obvious the moment you smell it.
  7. Which American city brewed and drank Kentucky Common?
    Answer: Louisville
    Louisville, from after the Civil War until Prohibition, where BJCP puts it at about 75 percent of local beer sales. Lexington is the tempting answer because it is the other Kentucky city most people can name. Cincinnati was a serious brewing town in the same period, and it brewed German lager rather than this.
  8. Louisville brewers fermented this beer warm and sold it within about a week. Which of these were reasons?
    Answer: The city could not harvest enough winter ice to store beer cold · Fermenting warm and selling fast was cheaper · Corn grits cost less than barley and made a lighter beer
    Climate, money and grain, in that order. Louisville is too far south to cut reliable ice, and cold storage is what a lager needs. The brewers went the other way and made an ale they could sell immediately. The oak ageing is the trap, and it is the opposite of the truth: this beer went from mash to sale in about a week.
  9. Before you read the panel. How bitter do you think a Pre-Prohibition Lager is, in IBU?
    Answer: 32IBU. A modern American Lager is 8 to 18 IBU. A German Pils is 22 to 40 IBU. Sahti is 0 to 15 IBU.
    About 32, with the range running 25 to 40 IBU. That puts it inside German Pils territory and roughly two to three times a modern American Lager. Most people guess low, because they assume an American corn lager must be mild, and mildness is exactly what this style lost afterwards.
  10. Match each beer in this group to its colour and bitterness.
    Answer: Pre-Prohibition Lager with SRM 3 to 6, and 25 to 40 IBU · Grodziskie with SRM 3 to 6, and 20 to 35 IBU · Kentucky Common with SRM 11 to 20, and 15 to 30 IBU · Roggenbier with SRM 14 to 19, and 10 to 20 IBU · Sahti with SRM 4 to 22, and 0 to 15 IBU
    Two pale and bitter, two dark and gentle, and one that covers almost the whole colour chart with no bitterness at all. The pale pair is the hard one. Pre-Prohibition Lager and Grodziskie share a colour and nearly share a bitterness, so you separate them on smoke and strength instead.
  11. Which two decisions make a Roggenbier?
    Answer: Up to 60 percent malted rye, fermented with a wheat beer yeast
    The grain gives the pepper and the body, and the wheat beer yeast gives the banana and clove. The third option is the tempting one because it describes a Rye IPA, which uses the same grain to a completely different end. The barrel answer is a different beer entirely.
  12. Which of these would you notice in a well made Roggenbier?
    Answer: Black pepper and banana in the same smell · A thick tan head that stays put · A fuller body than the colour prepares you for
    Pepper from the rye, banana from the yeast, and a body that rye builds without adding colour. The sour bite is the trap, and it belongs to a different family altogether. Nothing in this style is soured, and a sour Roggenbier is a fault rather than a feature.

Sources disagree

How bitter a sahti is allowed to be.

  • BJCP 2021, 27A Sahti. 0 to 15 IBU, and the written description says no hop aroma and no hop flavour. The juniper does the balancing work that hops would normally do.
  • Brewers Association 2026, Finnish-Style Sahti. 15 to 30 IBU, with hop aroma and flavour described as very low to low rather than absent.

The gap is real and it is the whole character of the beer. The traditional Finnish drink is unhopped or barely hopped, which is why it tastes sweet and heavy with nothing cutting it. The American sheet starts where the BJCP one stops. If you ever meet an American brewed sahti, expect it to be noticeably more bitter than the Finnish original.

Sources disagree

Whether Kentucky Common was sour.

  • BJCP 2021, 27A Kentucky Common. Brewing records from around 1900 show no long acid rests, no sour mashing and no extended ageing. The style has a dry finish and no sourness, and the modern sour versions are likely a homebrewer invention.
  • Brewers Association 2026, Kentucky Common Beer. Early twentieth century brewing literature mentions a slight tartness developing during fermentation. If tartness appears in a modern version it should be at very low levels.

They are closer than they look. Neither says the beer was deliberately soured, and neither supports the sour mash story you will read almost everywhere. A faint tartness from a fast warm fermentation is plausible. A sharply sour beer sold as a Kentucky Common is a modern reinvention, and it is fair to ask the bar which one they have made.

Worth remembering

Finland juniper, Norway yeast, Poland smoke, Louisville corn, America hops, Bavaria rye.

Six places, six decisions, in the order the cards appear. Finland filters through juniper. Norway keeps a farm yeast. Poland smokes its wheat over oak. Louisville uses corn and sells the beer in a week. Pre-Prohibition America keeps the hops that modern American lager threw away. Bavaria swaps wheat for rye. If you can say the six pairs, you can place any of these names on a menu.

Covered in Module 1, Pale lagers

American Lager, and the numbers to compare against. American Lager sits at 4.2% to 5.3% and 8 to 18 IBU. Pre-Prohibition Lager is the same family at 25 to 40 IBU, which is the single most useful comparison in this class. Taught in Module 1.

Covered in Module 3, Hop forward ales

Rye IPA, the other rye beer you have met. Rye gives a dry peppery snap in both beers. Rye IPA pairs it with American hops and a clean yeast, where Roggenbier pairs it with banana and clove. Same grain, opposite intent. Taught in Module 3.

Covered in Module 4, Wheat beers

Where the banana comes from. Banana and clove are made by the yeast during fermentation, not added. Sahti gets them from Finnish baking yeast and Roggenbier gets them from a German wheat beer yeast. Taught once, in Module 4.

Check yourself

  1. Finnish sahti is stocked in most large American bottle shops.
    Answer: False
    False. Finnish producers barely export at all, and even in Finland sahti is mostly a local drink. This is one of the rare cases where the honest advice is to stop looking. The nearest thing you can actually buy is a Weizenbock, which gives you the same banana, clove and strength without the juniper.
  2. People say sahti tastes of gin because of the juniper. What is actually going on?
    Answer: The juniper goes in as branches and wood, so it reads as pine and resin, and the banana comes from baking yeast
    Branches, not berries, and they are there to filter the mash rather than to flavour it. Wood and needles give pine and resin, which is a long way from a gin bottle. The second option is tempting because it is how a modern brewer would add a botanical. Sahti is never boiled, so there is no boil to add anything to.
  3. Match each name in this group to the thing that actually defines it.
    Answer: Norwegian Farmhouse and Kveik with A family of farm yeasts, so it names the fermentation and not the recipe · Sahti with Juniper branches used as the filter, and no hops · Grodziskie with Oak smoked wheat malt and very high carbonation · Kentucky Common with Corn grits, and about a week from mash to sale · Pre-Prohibition Lager with Corn adjunct with a full hop charge on top · Roggenbier with Up to 60 percent malted rye with a wheat beer yeast
    Five of these are defined by an ingredient or a process. The sixth is defined by a microbe, which is why it sits oddly next to the others and why it is the one people get wrong. Kveik tells you how the beer was fermented and nothing at all about what was in it.
  4. Which of these suggest you would enjoy a beer fermented with kveik?
    Answer: You like tropical fruit flavours such as mango and pineapple · You do not mind a beer that looks hazy rather than clear · You enjoy a big fruity smell coming off a drink
    Kveik pushes tropical fruit esters, and it usually turns up in hazy beers where clarity was never the goal. Smoke is the trap, and it belongs to Grodziskie on this screen. Nothing about the yeast produces smoke, and a smoky kveik beer would be smoky because somebody smoked the malt.
  5. You see Grodziskie on a menu and you have never had one. Which is the most useful thing to say?
    Answer: A Grodziskie, please. How smoky is yours.
    Smoke level is the one thing that genuinely varies between examples, and it decides whether you will enjoy the glass. The souring question is the tempting one because a small pale unusual beer sounds like a Berliner Weisse, and Grodziskie has no sourness in it. Strength is settled: at 2.5% to 3.3% it is weaker than almost anything else on the list.
  6. Match each beer to the food that works with it, and notice the reason in each case.
    Answer: Grodziskie with Smoked fish, because smoke sits well beside smoke and the bubbles clear the oil · Sahti with Salted fish and rye bread, because salt is the only thing that cuts the sweetness · Kentucky Common with Fried chicken, because a light dry fizzy beer scrubs the grease · Roggenbier with Cured sausage and mustard, because the peppery rye lines up with the spice · Pre-Prohibition Lager with Sharp cheddar, because real bitterness holds up to salt
    Three separate mechanisms are working here: matching a flavour, cutting a flavour, and clearing fat. Sahti is the one people get wrong, because a strong sweet beer looks like a match for something rich, and what it actually needs is salt to push against.
  7. Both of these are dark. Sort each fact into the beer it belongs to.
    Answer: Corn grits, six row barley and a touch of black malt goes in Kentucky Common · Clear, with a head that fades quickly goes in Kentucky Common · Louisville, in the years before Prohibition goes in Kentucky Common · Malted rye and a wheat beer yeast goes in Roggenbier · Hazy, with a thick head that stays put goes in Roggenbier · Bavaria, from 1988 goes in Roggenbier
    Colour is useless here, since both land in the amber to brown band. Clarity and head do the work instead: a clear beer with a collapsing head against a hazy one with a head like meringue. One tastes of corn and finishes dry, the other tastes of pepper and banana.
  8. The historical record shows that Kentucky Common was made using a sour mash.
    Answer: False
    False, and this is the most repeated wrong fact in the whole group. BJCP 2021 says brewing records from around 1900 show no sour mashing, no long acid rests and no extended ageing. It is tempting because Louisville is bourbon country and sour mashing is a real distilling technique, so the story sounds like it ought to be true.
  9. You order a beer sold as a Pre-Prohibition Lager and it tastes much like an ordinary American lager. What is most likely?
    Answer: The brewery has put the name on a beer far gentler than the guideline, which is common
    The name is a marketing phrase as often as a recipe. Deer Brand is sold as a pre-Prohibition lager at 18 IBU, well under the 25 to 40 the guideline asks for. It is a perfectly good beer that simply does not show you the style. Staleness and cold are real problems, and neither of them removes bitterness the way a recipe choice does.
  10. Name the Wisconsin lager, brewed in Middleton with corn flakes in the grain bill, that BJCP lists as an example of Pre-Prohibition Lager.
    Answer: supper club
    Capital Supper Club, at 5.0% and 28 IBU, which puts it inside the guideline range and makes it the honest calibration point. Deer Brand is the tempting answer, because it is easier to find and the brewery uses the same words. At 18 IBU it is gentler than the style is meant to be.
  11. Both of these are central European beers defined by their grain. Sort each fact into the right one.
    Answer: Malted rye at up to 60 percent of the grain goes in Roggenbier · Dark reddish brown and hazy goes in Roggenbier · Black pepper and banana in the same mouthful goes in Roggenbier · Oak smoked wheat malt and nothing else goes in Grodziskie · Pale gold and bright goes in Grodziskie · Carbonated hard enough to prickle the tongue goes in Grodziskie
    One grain decision drives everything in each beer. Rye brings colour, body and pepper, so a Roggenbier is dark, hazy and fuller than it looks. Smoked wheat brings smoke and a huge head with almost no body, so a Grodziskie is pale, sharp and tiny. Neither is anything like the other in the glass.
  12. Put these four steps in the order that turns a dark German wheat beer into a Roggenbier.
    Answer: 1. Start from a Dunkles Weissbier, which is a dark German wheat beer 2. Swap most of the wheat for malted rye, up to 60 percent of the grain 3. Keep the wheat beer yeast, so the banana and clove stay where they are 4. Expect black pepper on top, and a fuller body than the colour suggests
    Start, swap, keep, then taste the result. The keeping step is the one that matters, because it is what separates this from a Rye IPA. Both beers put rye in the grain, and only one of them keeps a yeast that makes banana.
Module 10 done

You can place all six names, say what each one kept that modern brewing dropped, and tell somebody honestly which of them you can buy.

Four lines worth keeping
  • Kveik is a yeast, not a beer. Everything else here is a beer.
  • Sahti gets its banana from baking yeast and its pine from juniper branches.
  • Kentucky Common was almost certainly not sour mashed, whatever the internet says.
  • Pre-Prohibition Lager is the most useful of the six, because it shows you what American lager used to be.
