Dortmunder Actien Brauerei is a German brewery in the city of Dortmund, founded in 1868 by the businessmen Laurenz Fischer and Heinrich and Friedrich Mauritz together with master brewer Heinrich Herberz. Originally, it was called Herberz & Co Brewery (Bierbrauerei Herberz & Co.).
From 1959 to 1963, DAB switched from the old wooden to new aluminium barrels. The Hansa Brewery, a local competitor, was acquired in 1971. On its soil, DAB erected a new modern brewery, finished in 1983, at the time the largest of the Ruhr area. However, the cost of the acquisition of Hansa was substantial, and burdened DAB for years to come. Questionable decisions by the company management in the 1990s exacerbated the situation, leading to a collapse of the company brands and the increasing production of generic brands to make use of the capacities. Even the acquisition of the brand names of another local competitor in economic difficulties, the Kronen brewery, could not save the downward trend which to this day, even though the company is the last brewery in Dortmund, has not been fully stopped.
Most prominent stock holder today is the Radeberger group of breweries, which in turn belongs to the company founded by August Oetker, today one of the most prominent players in the German food and drink industry.
DAB produces a lager called Dab after their initials. It is exported worldwide.
The former Hansa Brewery is in the North-Central section of Dortmund, and today serves as the Dortmunder Actien Brauerei, which took over Dortmunder Hansa in 1971. The facility also houses the Dortmunder Brewery Museum. Before changing its name to Dortmunder Hansa, the beer was brewed in the same location, then called the Borussia Brewery. It is from this brewery that the football club Borussia Dortmund takes its name.
