Dampfbierbrauerei Zwiesel is a historic brewery located in Zwiesel, a town in the Bavarian Forest region of Germany. The brewery traces its roots back to 1889, when Wolfgang Pfeffer founded what became known as the first steam beer brewery in Zwiesel. This long heritage places the Dampfbierbrauerei among the pioneering establishments in the revival of Dampfbier, a traditional Bavarian beer style with deep regional roots. The brewery is particularly known for its Dampfbier, a top-fermented wheat-based beer style that sets it apart from the more common bottom-fermented lagers dominant in Bavaria. The modern interpretation of Dampfbier, as produced at Zwiesel, is referenced in brewing literature alongside other notable German examples such as those from Maisel in Bayreuth. This style is characterised by its use of wheat malt and top fermentation, giving it a flavour profile distinct from classic Weissbier. The Dampfbierbrauerei Zwiesel holds a notable place in German brewing history as a key source for the supposed origins of the Dampfbier style. The brewery is situated at Regener Straße 9-11 in Zwiesel and continues to represent a living piece of Bavarian brewing tradition in the heart of the Bavarian Forest.
