European-Germanic Origin Lager · Brewers Association 2018
Kellerbier Lagers are unfiltered lagered versions of German lager beer styles such as Munich-Style Helles, Dunkel, Dortmunder/Export, Bohemian Pilsener and German Pilsener. Sulfur and acetaldehyde should enhance the flavor of these beers. These unfiltered beers are packaged and served with low to moderate amounts of yeast. Contemporary versions may be filtered and dosed with yeast during packaging. When using these guidelines as the basis for evaluating entries at competitions, brewers may be asked to provide supplemental information about entries in this category to allow for accurate evaluation of diverse entries. Such information should include the underlying Germanic lager beer style upon which the entry is based.
