A historic brewery in Kaufbeuren, Bavaria, described as the oldest brewery in Swabia and marketed internationally under the ABK Beer name.
Last updated August 26, 2026
Overview
Aktienbrauerei Kaufbeuren is a historic brewery and beer brand based in Kaufbeuren, Bavaria, Germany. Its documented origins reach back to 1308, when a Kaufbeuren citizen, Heinrich der Twinger, transferred his property, including a brewhouse, to the town’s Holy Ghost Hospice. That brewhouse became the foundation for the brewing enterprise later associated with Aktienbrauerei Kaufbeuren. The company is commonly described as the oldest brewery in Swabia, although its corporate identity and name changed over several centuries as it acquired or absorbed other local brewing operations. The present name dates from 1920. The brewery’s history is closely linked to Kaufbeuren’s municipal and guild traditions. In 1325, the town’s brewers formed a guild that restricted local beer production to barley, hops, and pure water. This rule preceded the Bavarian Reinheitsgebot of 1516 by almost two centuries and is presented as an early expression of ingredient regulation in the town’s brewing culture. During the seventeenth century, the brewery became one of the first in Bavaria to produce wheat ales, a style that had previously been associated particularly with Bavarian royalty. The surviving brewery buildings, including their deep cellars, date from 1807. The business later developed a reputation in international beer competitions, receiving several awards from the late nineteenth century onward. Its brewing identity is associated with the use of Hallertau hops and locally sourced grains, with the company describing relationships with some agricultural suppliers as extending across many generations. Aktienbrauerei Kaufbeuren remained part of the local competitive landscape until 1997, when it acquired Rosen-Brauerei, described as its last remaining competitor in Kaufbeuren. The beginning of the 2000s brought changes in trading names and a change in the ownership structure, including a shift in the majority shareholding. The company reported an operating loss of approximately €600,000 in 2004/2005; this is a historical figure and does not establish its current financial condition. Ownership later consolidated around the American entrepreneur John Paul DeJoria. He acquired a 55 percent stake in 2013 and purchased the remaining 45 percent in September 2017. Under DeJoria’s ownership, the brewery became part of the ROKit group of companies and was promoted internationally under the ABK Beer name. The brand also gained wider visibility through sponsorship and branding on Williams Formula One racing cars in 2019. The business combines a local German brewery identity with international brand distribution. Its documented profile centers on traditional beer production, historical brewing heritage, wheat-beer experimentation, regional raw materials, and export-oriented ABK branding. Publicly available reference material does not provide a verified current management roster, a complete product catalogue, a current website address, or detailed contemporary financial data.
History
Aktienbrauerei Kaufbeuren traces its documented history to a 1308 property transfer in Kaufbeuren. In that year, Heinrich der Twinger, a citizen of the town, bequeathed his property to the local Holy Ghost Hospice. The property included a brewhouse, and this facility became the historical foundation of the brewery later known as Aktienbrauerei Kaufbeuren. The reference to 1308 makes the enterprise one of the oldest documented brewing operations in the region and supports its description as the oldest brewery in Swabia. The brewery’s identity developed gradually rather than appearing under its modern name from the outset. Over the centuries, the business changed names and acquired other brewing operations. The name Aktienbrauerei Kaufbeuren dates from 1920. “Aktienbrauerei” literally means “share brewery,” reflecting the company’s joint-stock ownership structure. Shares have been traded on the Munich Stock Exchange, although no ticker symbol is identified in the available reference material. Kaufbeuren also had an early organized brewing culture. The Kaufbeuren Brewers Guild was established in 1325 and declared that beer made in the town should use only barley, hops, and pure water. Other ingredients were prohibited under the guild’s local rules. This formulation predates the Bavarian Reinheitsgebot of 1516 by nearly two centuries. The guild tradition is therefore an important part of the brewery’s historical positioning, even though the modern company should not be treated as identical to the medieval guild. During the seventeenth century, the brewery became one of the first in Bavaria to produce wheat ales. At that time, wheat beer was particularly associated with Bavarian royalty and was not broadly available in the same way as later commercial wheat beers. This development connected the brewery with a style that remains central to Bavarian brewing heritage. The present brewery buildings and deep cellars were constructed in 1807. The cellars and historic premises represent the physical continuity of the Kaufbeuren brewing site, although the available source does not provide a complete architectural or preservation history. From the late nineteenth century onward, the brewery won several international beer competitions, indicating that its reputation extended beyond the immediate local market. Raw-material sourcing is another recurring element of the brewery’s identity. The company is associated with Hallertau hops and grains grown locally. The available account states that some supplier relationships extend back more than 700 years, although it does not identify each farm or provide a complete documentary chain for those relationships. In 1997, Aktienbrauerei Kaufbeuren purchased Rosen-Brauerei, described as the last remaining competing brewery in Kaufbeuren. This transaction strengthened the company’s position in its home town. During the early 2000s, the business experienced changes to its trading names and to the ownership of a majority of its shares. It reported an operating loss of approximately €600,000 in the 2004/2005 period. Ownership changed substantially in the following decade. John Paul DeJoria acquired 55 percent of the company in 2013 and bought the remaining 45 percent in September 2017. Following the acquisition, the brewery became part of DeJoria’s ROKit group of companies. Its beer was marketed internationally using the ABK Beer name, giving the historically local brewery a more export-oriented brand identity. In 2019, ABK Beer appeared on Williams Formula One racing cars, providing a prominent international marketing association. The available reference material supports a picture of a long-established Bavarian brewery with a documented medieval origin, a joint-stock corporate tradition, a historic production site, local consolidation through the Rosen-Brauerei acquisition, and later international promotion under ROKit ownership. It does not provide enough verified information to list current directors, production volumes, revenue, detailed distribution territories, or a complete modern product range.
