For the purposes of this competition, these are unfiltered German-style Altbier and Kölsch entries only. They 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. These beers may or may not portray a yeasty mouthfeel depending on the amount of yeast contained in the package and dispensed during pouring. They will most likely not be clear, and may appear slightly hazy to moderately cloudy. Yeast flavor and aroma should be low to medium but not 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 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. Head retention may not be optimal.
