Fetească Regală and the clonal selections at Gräfenberg
At Gräfenberg, Michael jun. makes clonal selections of Mädchentraube (Fetească), Königsast and Italian Riesling. The name Fetească Regală probably dates from the same years, and his selected Riparia × Berlandieri rootstocks are marketed as «Selecția Ambrosi».
