Kellerbier (Cellar beer) or Zwickelbier - Ale

Kellerbier (Cellar beer) or Zwickelbier - Ales are the color of the underlying German ale style. Appearance may or may not be clear, so may appear slightly hazy to moderately cloudy. Exhibiting a small amount of yeast haze is acceptable. These beers are unfiltered, but may be naturally clear due to settling of yeast during aging. Head retention may not be optimal. Kellerbier Ales are unfiltered German-style Altbier and Kölsch. Aromas typical of the underlying beer style are present. Yeast aroma is desirable, yet should be low to medium without overpowering the balance and character of malt and hops. Low to moderately low levels of yeast-generated sulfur-containing compounds should be apparent in aroma, and low levels of acetaldehyde or other volatiles normally removed during fermentation may or may not be apparent. Hop aroma is sometimes suppressed by the presence of yeast, depending on style. Malt character will vary with style (see individual style descriptions). Hop flavor is sometimes suppressed by the presence of yeast, depending on style. Hop bitterness is sometimes suppressed by the presence of yeast, depending on style. Yeast flavor is desirable, yet should be low to medium without overpowering the balance and character of malt and hops. Low to moderately low levels of yeast-generated sulfur containing compounds should be apparent in flavor, and low levels of acetaldehyde or other volatiles normally removed during fermentation may or may not be apparent. The sulfur and acetaldehyde characters should contribute positively to the beer drinking experience. These unfiltered German-style ales are packaged and/or served intentionally with low to moderate amounts of yeast. Products may be filtered and again dosed with yeast in the package, manifesting themselves as bottle conditioned beers or unfiltered beer with yeast present. During registration brewers may specify pouring instructions, choosing normal pouring, quiet pouring or intentional rousing of yeast. Entries will be presented during judging as specified by entering brewer. Body is variable with style. The brewer must indicate the classic style on which the entry is based to allow for accurate judging. Beer entries not accompanied by this information will be at a disadvantage during evaluation.
