Lagers must be made only from barley malt, water, hops and yeast
Ales can include wheat malt and pure sugars. (G)
What does Mai mean?
The month of May
What does Doppel mean?
“Double” BUT in German beers the word usually indicates a modest increase in malt and alcohol rather than a literal doubling
Name 3 different malts commonly used as the base of each recipe
Munich malt
Pilsner malt
wheat malt
What kind of malt forms the base for nearly all Munich lager styles?
Munich malt
What 2 styles of lager from Munich don’t use Munich malt as their base malt?
Munich Helles & Helles Bock
What color do beers brewed exclusively from Munich malt turn out?

Pilsner malt
Are Pilsner malts very pale, pale or dark in color?
Very pale
What are Pilsner malts named after?
The Czech city of Pilsen
Why were Czech brewers from the city of Pilsen able to produce such pale malts?
Softness of their water
Today, how do brewers produce Pilsner malts pale color?
A short and low temperature kilning
What flavors do Pilsner malts usually give in beer?
Unsalted saltine crackers, very light matzo or water crackers
Pilsner malts may contain a small amount of DMS. What flavors can DMS contribute to a very pale beer?
A hint of creamed corn flavor
In Germany, what kind of malt typically makes up the majority of the grist for Weizen style beers?
Wheat malt
What are the flavors typically contributed by wheat malt in beer?
Bread-like or flour-like
Are wheat malts pale or dark in color?
Most are pale in color but on rare occasion there may be roasted or crystal wheat malts.
Where do some brewers still make smoke-flavored malt?
In the north of Bavaria around the town of Bamberg.
What does the German word “rauch” mean?
Smoke
How does malt take on its smoke flavor for a rauch beer?
In a kiln fired with wood when the malt is wet so it can be absorbed (direct kilning)
Which other malt is similar in character to Munich malt?
Vienna malt
Why are crystal malts not used in German beers very often?
The malting procedures that produce crystal malt weren’t developed until after most lager styles were established.
What is farb malt?
Black malt. Rarely seen. Gives a lot of color but little flavor when used in small amounts.
What are the 4 Nobel Hops?
Hallertauer Mittelfrüh
Tettnanger
Spalt
Saaz
Why do the Nobel Hops carry that name?
They are the hops that have been traditionally used in German & Czech brewing that are especially prized for their aroma and flavor.
What are typically the aromas used to describe the Nobel Hops
Floral, perfumy, woodsy and spicy with mint and even cinnamon notes.
What is the ideal fermentation temperature for lager yeast?
47-50 degrees F which is about 15-20 degrees F cooler than ideal temp for most ale yeast strains.
When making lager beer, what happens after primary fermentation?
Lagering - a period of cold conditioning which takes place at 32-35 degrees F
How long does “lagering” take?
Anywhere from as short as 10 days to as long as many months.
Why do lagers display little to none of the fruity esters found in ales?
The cooler fermentation and extended lagering period.
What flavors play the primary roles in overall flavor profile for lagers?
Malt & hops
In German brewing tradition, what are the only common ale styles?
Kölsch & Altbier
Where did kölsch & altbier originate from?
Rhine Valley in western Germany
How are kölsch and altbier made and how do they compare to other ales?
With ale yeast, fermented at cooler temperatures than normally used for ale yeast. Impacting the beer to have a reduced ester profile compared with other ales.
Ale yeast strains used in making kölsch and altbiers are usually highly attenuative. What does that contribute to the beer?
Dry finish characteristic of these styles.
What are German Weizen beer known for?
A unique yeast strain that is known for its characteristic flavor profile.
What phenolic compound does Weizen yeast produce that gives a spicy flavor often described like clove?
4-vinylguaiacol
What is the name of the ester that is produced in substantial amounts in Weizen yeast that tastes like banana?
Isoamyl acetate
What is lactobacillus?
A non-saccharomyces (non-yeast) fermentation organism that produces large amounts of lactic acid.
Lactic acid - producing bacteria are essential to the production of which style of beer?
Berliner Weisse
Which 2 cities set the stage for the types of beers that each city is famous for?
Munich & Pilsen
Describe Munich water
High hardness with an especially high calcium carbonate level.
Why did Munich brewers primarily brew dark lagers?
Prior to adequate knowledge of water chemistry and treatment, the high level of hardness made it difficult for brewers to produce pale malts.
What is Pilsen known for?
It’s incredibly soft water.
What did Pilsens iconic soft water help them produce?
Pale malts and consequently a pale beer.
What did Pilsens low mineral content in their water allow for the brewers of Pilsen to do to their beer?
Employ higher hopping rates without producing a harsh bitterness.
What is an important technique employed in brewing the majority of German styles?
Lagering
Describe primary fermentation
Occurs prior to lagering and takes place at 47-50 F for 5-7 days.
Why does lager fermentation take longer than ale fermentation?
The lower temperatures used.
When does lagering occur and what does it do to the beer?
After primary fermentation. The beer is separated from any dead yeast and debris that has settled out and is then cooled.
What temperature is beer lagered at?
32-35 degrees F
What absorbs and reduces sulfur compounds formed during primary fermentation in lagers?
Yeast
How long does lagering usually last?
2-6 weeks
What style of beer may require longer lagering to develop desired flavor profile in strong beers?
Doppelbock
How long can lagering last?
As little as 10 days or as long as several months.
What will the flavor profile of the beer be after lagering is completed?
Malt and hop flavors with little or no flavor contributed by the yeast and a profile free of significant sulfur, ester or aldehyde
Describe the mashing technique “infusion”
Mixing ground malt with hot water and raising temperatures of the mixture to the desired temperature(s)
How do brewers increase mash temperatures?
By removing a portion of the mash from the mash tun and bringing it to a boil before adding it back and mixing it with the mash.
Name some ways the additional heating in decoction mashing contributes to the finished beer.
Darkens the color and may contribute bready, toasty, and bread crust flavors.
Malting technology has improved greatly and is no longer necessary so why do some breweries still use decoction mashing today even though similar flavors can be achieved using specialty malts?
For the rich malt flavors that are produced during the process.
What is bottle conditioning?
The practice of carbonating beer through a secondary fermentation following packaging rather than by force-carbonating the beer prior to packaging. They do this by having some viable yeast and fermentable sugar in the bottle at packaging time and the carbonation will develop within a couple weeks.
What does bottle condition aid the beer in?
Preservation. The remaining viable yeast will scavenge any oxygen effectively guarding against oxidation
What kind of flavor can bottle conditioning impart on a finished beer?
Yeasty
If a bottle conditioned beer autolyzes from being left for too long, what undesirable flavors can it impart on the beer?
Rubbery, soy and umami
What style of beer do German brewers commonly bottle condition?
Weizen-style beers
What is the serving size for most German lagers?
Half-liter (16.9oz)
How many ounces are served for higher alcohol lagers like doppelbock?
Third-liter (10.1oz) or quarter-liter (8.5oz)
Most draft faucets include a type of mechanism to achieve the proper foam level called what?
A “creamer”
What do German draft systems often use to push the beer from the keg in the cooler to the faucet in the bar?
Carbon dioxide pressure
How many beers are offered at any bar or pub in Germany at one time?
Typically 2-4
What does Keller mean?
“Cellar”
What does the word “zwickel” describe?
A special valve used for drawing beer samples from large, lagering tanks.
How are kellerbiers and zwickelbiers described?
A hazy, lightly carbonated and very fresh serving of beer taken directly from the lagering tank.
What style of beer will you find is nearly universally bottle conditioned?
Hefeweizen-style beers
What was the everyday drinking beer of Munich for several centuries?
Munich Dunkel
What is the everyday drinking beer of Munich today?
Munich Helles
What does dunkel mean?

Schwarzbier most likely evolved as a darker version of what style?
Dunkel
Most examples of schwarzbiers are what color?
Dark brown
If a brewery produces both a Dunkel and a Schwarzbier why will the Schwarzbier always be darker?
Due to the inclusion of a small portion of roasted malt in the grain bill.
What role do hops play in Schwarzbier?

Festbier
For hundreds of years, Märzen brewing occurred seasonally between which months?
October - March
In the 1940s what did Gabriel Sedlmayr and Anton Dreher contribute to the evolution of märzen lagers?
Introduced indirect kilning - transforming the rough, inconsistent (and probably smoky) malts of yore into something more closely akin to those available today.
Key flavors for Märzen lagers

Festbier
What started Oktoberfest?
The wedding of Crown Prince Ludwig in 1810 and then the annual celebrations after that.
At one time märzen and festbier were indistinguishable. How do modern festbiers generally look?
Pale in color as a concession to current consumer tastes.
