In 2007, DNA analysis confirmed that Grüner Veltliner was a natural crossing of Savagnin (Traminer) and obscure Austria grapevine from the village of Sankt Georgen am Leithagebirge located outside Eisenstadt in Burgenland region of eastern Austria [REF].
St. Georgener-Rebe was once known under the synonym Grün Muskatellar but appears to have no direct relationship to the Muscat family of grapes.
