medium bodied. There is a noticeable degree of caramel-type malt character in

Category 37: Bohemian Pilsener
Bohemian pilseners are medium bodied, and they can be as dark as a light amber color. This style balances moderate bitterness and noble-type hop aroma and flavor with a malty, slightly sweet, medium body. Extremely low levels of diacetyl and low levels of sweet corn-like dimethylsulfide (DMS) character, if perceived, are characteristic of this style and both may accent malt aroma. A toasted-, biscuit-like, bready malt character along with low levels of sulfur compounds may be evident. There should be no chill haze. Its head should be dense and rich.
Alcohol by Weight: 3.2-4%
Color SRM: 3-7
Category 38: German Lager/Pilsener
A classic German Pilsener is very light straw or golden in color and well hopped. Hop bitterness is high. Noble-type hop aroma and flavor are moderate and quite obvious. It is a well-attenuated, medium-light bodied beer, but a malty residual sweetness can be perceived in aroma and flavor. Very low levels of sweet corn-like dimethylsulfide (DMS) character are below most beer drinker’s taste threshold. Other fermentation or hop related sulfur compounds, when perceived at low levels, may be characteristic of this style. Fruity esters and diacetyl should not be perceived. There should be no chill haze. Its head should be dense and rich.
Alcohol by Volume: 4-5%
Color SRM: 3-4
Category 39: Münchner Helles
This beer should be perceived as having low bitterness. It is a medium-bodied, malt-emphasized beer; with malt character often balanced with low levels of yeast produced sulfur compounds (character). Certain renditions of this beer style approach a perceivable level of hop flavor (note: hop flavor does not imply hop bitterness) and character but it is essentially balanced with malt character to retain its style identity. Malt character is sometimes bread-like yet always reminiscent of freshly and very lightly toasted malted barley. There should not be any caramel character. Color is light straw to golden. Fruity esters and diacetyl should not be perceived. There should be no chill haze.
Alcohol by Weight: 3.8-4.4%
Color SRM: 4-5.5
Category 40: Münchner Dunkel/Dark Larger
Subcategory: Münchner Dunkel
These light brown to dark brown beers have a pronounced malty aroma and flavor that dominates over the clean, crisp, moderate hop bitterness. This beer does not offer an overly sweet impression, but rather a mild balance between malt sweetness, hop bitterness and light to moderate mouthfeel. A classic Münchner Dunkel should have a chocolate-like, roast malt, bread-like or biscuit-like aroma that comes from the use of Munich dark malt. Chocolate or roast malts can be used, but the percentage used should be minimal. Noble-type hop flavor and aroma should be low but perceptible. Diacetyl, ale-like fruity esters and chill haze should not be perceived.
Alcohol by Weight: 3.8-4.2%
Color SRM: 15-20

Hop bitterness, flavor, and aroma are low. Carbonation is high. Fruity esters, diacetyl, and chill haze should not be perceived.
Alcohol by Weight: 3.2-4.4%
Color SRM: 14-25
Märzens are characterized by a medium body and broad range of color. They can range from golden to reddish orange. Sweet maltiness should dominate slightly over a clean, hop bitterness.

Diacetyl and chill haze should not be perceived.Category 42: Schwarzbier
Alcohol by Weight: 4-4.7%
Color SRM: 4-15

Noble-type hop flavor and aroma should be low but perceptible. There should be no fruity esters. Diacetyl should not be perceived.
Alcohol by Weight: 3-3.9%

Category 43: Bock
Subcategory: German Bock
Traditional bocks are made with all malt and are strong, malty, medium- to full-bodied, bottom-fermented beers with moderate hop bitterness that should increase proportionately with the starting gravity. Hop flavor should be low and hop aroma should be very low. Bocks can range in color from deep copper to dark brown. Fruity esters should be minimal.
Alcohol by Weight: 5-6%
Color SRM: 20-30
Subcategory: German Heller Bock/Maibock
The German word helle means light colored, and as such, a heller Bock is light straw to deep golden in color. Maibocks are also light-colored bocks. The malty character should come through in the aroma and flavor. Body is medium to full. Hop bitterness should be low, while noble-type hop aroma and flavor may be at low to medium levels. Bitterness increases with gravity. Fruity esters may be perceived at low levels. Diacetyl levels should be very low. Chill haze should not be perceived.
Alcohol by Weight: 5-6.4%
Color SRM: 4-10
Category 44: Strong Bock
Subcategory: German Strong Doppelbock
Malty sweetness is dominant but should not be cloying. Malt character is more reminiscent of fresh and lightly toasted Munich-style malt; more so than caramel or toffee malt character. Some elements of caramel and toffee can be evident and contribute to complexity, but the predominant malt character is an expression of toasted barley malt. Doppelbocks are full bodied and deep amber to dark brown in color. Astringency from roast malts is absent. Alcoholic strength is high, and hop rates increase with gravity. Hop bitterness and flavor should be low and hop aroma absent. Fruity esters are commonly perceived but at low to moderate levels.
Alcohol by Weight: 5.2-6.2%
Color SRM: 12-30
Subcategory: German Strong Eisbock
A stronger version of Doppelbock. Malt character can be very sweet. The body is very full and deep copper to almost black in color. Alcoholic strength is very high. Hop bitterness is subdued. Hop flavor and aroma are absent. Fruity esters may be evident but not overpowering. Typically these beers are brewed by freezing a Doppelbock and removing resulting ice to increase alcohol content.
Alcohol by Weight: 6.8-11.3%
Color SRM: 18-50
Category 45: Baltic-Style Porter
A true smooth cold-fermented and cold lagered beer, brewed with
lager yeast. Black to very deep ruby/garnet in color. Overall,
Baltic Porters have a very smooth lagered character with distinctive
caramelized sugars, licorice and chocolate-like character of roasted
malts and dark sugars. Roasted dark malts should not contribute
bitterness, or astringent roast character. A low degree of smokiness
from malt may be evident. Debitterized roast malts are best used for
this style. Because of its alcoholic strength, aroma may include
gentle (low) lager fruitiness (berries, grapes, plums, not banana;
ale-like fruitiness from warm temperature fermentation is not
appropriate), complex alcohols, cocoa-like, roast malt (and
sometimes coffee-like roast barley, yet not bitter). Hop aroma is
very low, though a hint of floral or sweet hop aroma can complement
aromatics and flavor without dominance. Baltic Porters are not hop
bitter dominated and expressed as low to medium-low. Baltic porters
range from having medium to full body complemented with a medium-low
to medium level of malty sweetness. No butterscotch-like diacetyl or
sweet corn-like dimethylsulfide should be apparent in aroma or
