The red grape variety (also Freiburg 364-80 R) is a new breeding between GM 6423-14 (Rotberger x Heroldrebe) x Freiburg 054-64 r (Deckrot x Freiburg 589-54). It contains genes from Vitis berlandieri, Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera via the father population. The hybrid was crossed in 1980 at the State Viticultural Institute in Freiburg(Baden-Württemberg). The late-ripening, frost-hardy vine is resistant to both powdery mildew and botrytis and therefore belongs to the PIWI varieties. In addition, it is only slightly susceptible to stem rot and trickling. The variety produces dark, colour-intensive red wines that are suitable as Teinturier (colouring wine). It is cultivated in the German growing region of Baden. In 2018, five hectares of vineyards were designated in Germany (D-STATIS).
