Kellerbier (German: [ˈkɛlɐˌbiːɐ̯] ; cellar beer) is a type of German beer, an unfiltered lager originating in Franconia.[1]

Kellerbier contains more of its original brewing yeast, held in suspension. As a result, it is distinctly cloudy, and is described in German as naturtrüb (naturally cloudy).[2]

Kellerbier is often served directly from the barrel in a beer garden, but may be bottled as well.


The term Zwickelbier (German: [ˈt͡svɪkl̩ˌbiːɐ̯] ), regionally Zwickel or Zwickl, refers to a weaker and less full-flavored variant of Kellerbier.[3] Originally, it was used to refer to the small amount of beer taken by a brewmaster from the barrel with the aid of a special siphon called the Zwickelhahn.

It is less hoppy, and typically not left to age as long as Kellerbier.[3]
