The red grape variety (also VB 91-26-17) is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. It is believed to be a complex cross between Cabernet Sauvignon x(Silvaner x(Riesling x Vitis vinifera) x (JS 12417 x Chancellor)) as well as the new Cabernet Blanc and Pinotin varieties. Accordingly, genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera would be included. The hybrid was crossed in 1991 by the breeder Valentin Blattner in Soyhières in the Swiss canton of Jura, the selection then took place in the Freytag nursery in the municipality of Neustadt/Lachen-Speyerdorf Germany (Palatinate). The medium to late-maturing frost-hardy vine is resistant to botrytis and both types of mildew, which is why it is considered a PIWI variety. It produces deep dark red wines with aromas of blackcurrants and black cherries. The variety is grown in small quantities in Switzerland (2 ha), Germany and Belgium. In 2016, however, only stocks in Switzerland were identified (Kym Anderson).
