Category 44: 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.
OG: 1.044-1.056
FG: 1.014-1.020
Alcohol by Weight: 3.2-4%
IBU: 30-45
Color SRM: 3-7 
 
Category 45: 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.
OG: 1.044-1.050
FG: 1.006-1.012
Alcohol by Volume: 4-5%
IBU: 30-40
Color SRM: 3-4

    

Category 46: 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.
OG: 1.044-1.050
FG: 1.008-1.012
Alcohol by Weight: 3.8-4.4%
IBU: 18-25
Color SRM: 4-5.5
 
Category 47: 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.
OG: 1.052-1.056
FG: 1.014-1.018
Alcohol by Weight: 3.8-4.2%
IB): 16-25
Color SRM: 15-20
    
Subcategory: Dark Lager
This beer's malt aroma and flavor are low but notable. Its color ranges from a very deep copper to a deep, dark brown. Its body is light. Non-malt adjuncts are often used, and hop rates are low. Hop bitterness, flavor, and aroma are low. Carbonation is high. Fruity esters, diacetyl, and chill haze should not be perceived.
OG: 1.040-1.050
FG: 1.008-1.012
Alcohol by Weight: 3.2-4.4%
IBU: 14-20
Color SRM: 14-25   
  

Category 48:  Märzen/Oktoberfest

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. Malt character should be light-toasted rather than strongly caramel (though a low level of light caramel character is acceptable). Bread or biscuit-like malt character is acceptable in aroma and flavor. Hop aroma and flavor should be low but notable. Ale-like fruity esters should not be perceived. Diacetyl and chill haze should not be perceived.
OG: 1.050-1.060
FG: 1.012-1.020
Alcohol by Weight: 4-4.7%
IBU: 18-25
Color SRM: 4-15
 
Category 49: Schwarzbier
These very dark brown to black beers have a mild roasted malt character without the associated bitterness. This is not a full-bodied beer, but rather a moderate body gently enhances malt flavor and aroma with low to moderate levels of sweetness. Hop bitterness is low to medium in character. Noble-type hop flavor and aroma should be low but perceptible. There should be no fruity esters. Diacetyl should not be perceived.
OG: 1.044-1.052
FG: 1.010-1.016
Alcohol by Weight: 3-3.9%
IBU: 22-30
Color SRM: 25-30

 

 

Category 50: 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.
OG: 1.066-1.074
FG: 1.018-1.024
Alcohol by Weight: 5-6%
IBU: 20-30
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.
OG: 1.066-1.074
FG: 1.012-1.020
Alcohol by Weight: 5-6.4%
IBU: 20-38
Color SRM: 4-10

Category 51: 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.
OG: 1.074-1.080
FG: 1.014-1.020
Alcohol by Weight: 5.2-6.2%
IBU: 17-27
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.
OG: 1.092-1.116
Alcohol by Weight: 6.8-11.3%
IBU: 26-33
Color SRM: 18-50
 

 

 
Category 52: 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 flavor.
Original Gravity: 1.072-1.085
Final Gravity: 1.016-1.022
Alcohol by Volume:7.5-9%
Bitterness (IBU): 35-40
Color SRM (EBC): 40+ (80+ EBC)
