Kellerbier

Originally, Kellerbier referred to any Lager beer being matured in the caves or cellars under the brewery. In the 19th century, Kellerbier was a strong, aged beer meant to last the summer (Sommerbier), stored in rock cellars and served straight from them. But when refrigeration began to be used, the term shifted to describing special beers that were served young, directly from the cellar or lagering vessel. Today some breweries use the term purely for marketing purposes to make their beers appear special. While a kellerbier is sometimes considered more of a serving style than a beer style, the serving technique is still predominately used with certain styles in certain regions (such as Helles around the Munich area, or a Märzen in the Franconia region). Young, unfiltered, unpasteurized versions of the traditional German beer styles, traditionally served on tap from the lagering vessel. The name literally means “cellar beer” – implying a beer served straight from the lagering cellar. Since this serving method can be applied to a wide range of beers, the style is somewhat hard to pin down. However, there are several common variants that can be described and used as templates for other versions. Sometimes described as Naturtrüb or naturally cloudy. Also sometimes called Zwickelbier, after the name of the tap used to sample from a lagering tank.
