In 1998 the Brau Union Österreich AG was founded from the merge between Österreichische Brau AG and Steirerbrau. This was followed in 2003 by the acquisition of 33% of the shares in the Schladming brewery, which was increased to 90% in 2005. Brau Union Österreich has been part of the parent company Heineken, based in Amsterdam, since 2003.
