The red grape variety (also VB 91-26-17) is an interspecific new cross between Cabernet Sauvignon x unknown resistance partners. It is assumed to be a complex cross between Cabernet Sauvignon x (Silvaner x (Riesling x Vitis vinifera) x (JS 12417 x Chancellor)) as is the case with the new varieties Cabernet Blanc and Pinotin. 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, then selected in the Freytag vine nursery in the municipality of Neustadt/Lachen-Speyerdorf Germany (Palatinate). The medium to late ripening 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 cassis (blackcurrants) and black cherries. The variety is cultivated in small quantities in Switzerland (2 ha), Germany and Belgium. In 2016, however, only stocks in Switzerland were reported (Kym Anderson).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
