Siegerrebe (literally "Victory vine" in German) is a white wine grape that is grown primarily in Germany with some plantings in England, Washington State, British Columbia's North Okanagan and Nova Scotia's Annapolis Valley. Siegerrebe was created by German viticulturalist Dr. Georg Scheu (1879-1949) in 1929 at a grape-breeding institute in Alzey in Rheinhessen, by crossing Madeleine Angevine and Gewürztraminer. However, Georg Scheu's son Heinz Scheu has claimed in a book that Siegerrebe was the result of self-pollination of Madeleine Angevine. Siegerrebe received varietal protection and was released for general cultivation in Germany in 1958.
In 2006, there were of Siegerrebe in Germany with a decreasing trend, in similarity with other "new breeds" of white varieties. In Belgium, it is authorised for all still wine AOCs : Côtes de Sambre et Meuse, Hageland, Haspengouw, et Heuvelland.
