A winegrowers' association or regional brand in the Lower Austrian winegrowing region of Wachau for dry quality white wines typical of their origin. It was founded in 1983 by the four Wachau winegrowing pioneers Franz Hirtzberger sen. (1922-2007), Josef Jamek, Franz Prager and Willi Schwengler as directors of the Wachau winegrowers' cooperative (today Domäne Wachau). Among other things, they wanted to create an area-protected brand, which was directed against the then widespread practice of buying wines from other Lower Austrian wine-growing regions and marketing them as Wachau wine. The name was used by the Austrian nobleman Leuthold I von Kuenring (1243-1313), who resided at his castle in Dürnstein, to designate the core of his possessions, which corresponded to today's Wachau. His portrait is included on the label, but instead of a sword he carries a wine goblet in his right hand. The chairman of the association was Franz Hirtzberger Jr. for 24 years, his successor since 2012 is Emmerich Knoll.
