Dortmunder Aktien-Brauerei (DAB) beer

Dortmunder Aktien-Brauerei, commonly known as DAB, is a historic brewery located in Dortmund, Germany. Founded in 1867 by businessmen Laurenz Fischer, Heinrich Mauritz, and Friedrich Mauritz, the brewery gained fame for its 'Dortmunder Export' style of lager, which became highly popular internationally during the late 19th and early 20th centuries.

The production remains centered in Dortmund, adhering to the German Purity Law (Reinheitsgebot). While the brand has historical significance as an independent stock company, it was eventually integrated into larger corporate structures to maintain its global distribution network.

Today, DAB is a flagship brand of the Radeberger Gruppe, which is the beer division of the Oetker Group (Dr. August Oetker KG). This ownership ensures that the traditional Dortmund brewing heritage is preserved while benefiting from the logistical reach of Germany's largest private brewing group.
