Austrian winemaker Fritz Wieninger grew up in the family heurigen (wine taverns), serving wines produced by his mother, who was one of the first female graduates from the Klosterneuburg - Enology Program. Today, Fritz Wieninger is the leading wine producer in the city of Vienna and is a champion of Gemischter Satz, a traditional field blend and a favorite wine in Vienna’s heurigen. Due to his consistent focus and pursuit of quality, Fritz concluded that biodynamic farming was essential to have the best possible wines. The basis of this decision was founded on the belief that healthy soil would promote natural vineyards that would allow flora and fauna to thrive. The Wieninger family cultivates their vineyards in the Nussberg, in the 19th district, and the Bisamberg, in the 21st district of Vienna, which is also where the Wieninger Winery is located. A wide range of wines results from these two areas, whose climates differ due to the separation created by the Danube River.
