Kellerbier or Zwickelbier

Notes

Kellerbier or Zwickelbiers are unfiltered versions of lager or ale styles of European origin. These can include traditional Helles, Dunkel, Dortmunder, Vienna, Rotbier, Bohemian, European Dark, Koelsch, Alt, as well as less common traditional or contemporary European-origin lager and ale styles. Carbonation may be below levels typical of the underlying beer style, which may result in decreased head retention. These beers are typically unfiltered, but they may be filtered and then redosed with yeast. Whether filtered or unfiltered these beers are packaged and served with very low to moderate amounts of yeast. 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 European-origin lager or ale style upon which the entry is based. Competition organizers may create subcategories which reflect groups of entries based on ale or lager yeast type or hue.
