Aktien Zwick’l Kellerbier

Aktien Zwick’l is a traditional German Kellerbier (cellar beer) produced by the Bayreuther Bierbrauerei in Upper Franconia, Bavaria. This specific style of beer is known for being unfiltered, naturally cloudy, and yeast-rich, historically sampled directly from the barrel by the brewmaster using a 'Zwickelhahn' (sampling tap), from which the name is derived.

The brand has deep roots in the city of Bayreuth, where the brewery was founded in 1857. While it maintains its independent identity and traditional brewing methods, the Bayreuther Bierbrauerei is part of the Brauerei Gebrüder Maisel family, another historic Bayreuth institution. The beer is packaged in a distinctive swing-top bottle (Bügelverschluss), emphasizing its traditional heritage. Production remains concentrated at the original site in Bayreuth to ensure the authenticity of this regional specialty.
