The white grape variety (also Hybernal, GM 322-58) is a new variety between (Seibel 7053 = Chancellor x Riesling) x (Seibel 7053 x Riesling). It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1944 by Heinrich Birk (1898-1973) in Geisenheim (Rheingau). The plant variety protection was granted in 1977. The late ripening, frost hardy vine is resistant to both mildew and botrytis and is considered a PIWI variety. It produces fresh, fruity white wines that can have a subtle foxtone. It was cultivated in 2010 in Germany (Rheinhessen wine region) on one hectare of vineyard area. Small stocks are also to be found in the Czech Republic and Canada.
