Privatbrauerei Zwettl is an Austrian family brewery with roots stretching back to 1708, located in Zwettl in the Waldviertel region of Lower Austria. Now in its fifth generation of ownership under the Karl Schwarz family, the brewery has maintained its independence for over three centuries, making it one of the most enduring private breweries in Austria. Its long history in the Waldviertel — a region known for its agricultural heritage — has shaped a brewing philosophy rooted in tradition and regional identity. The brewery produces a range of beers that reflect its Austrian heritage, including its Kellerbier, for which it has gained recognition in the broader European craft and traditional beer market. The Zwettler portfolio is known for quality-driven lagers and speciality styles suited to the Waldviertel's character. Among its more recent releases is the Zwettler Frei, a refreshing beer described as light and zesty, broadening the brewery's appeal to contemporary beer drinkers while staying true to its artisanal roots. Privatbrauerei Zwettl has continued to invest in its production infrastructure, including the installation of a new pipe bridge crossing the main road as part of a modern "Beer Pipeline" project, demonstrating its commitment to long-term growth. With over 300 years of brewing history, Zwettl remains a proud symbol of Austrian regional brewing craft.
