The red grape variety is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. Synonyms VB 91-26-29 and Valentin Blattner 91-26-29. It contains genes from Vitis amurensis and Vitis vinifera. 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 vine is resistant to frost, botrytis and both types of mildew. It yields deep dark red wines with aromas of blackberries, blackcurrants (cassis), black pepper and dark chocolate with hints of cigar, leather and cedar. The variety is grown in small quantities in Switzerland and Germany (e.g. Weingut Galler Ansgar in the Palatinate). In 2016, a vineyard area of 0.1 hectares was reported (Kym Anderson statistics).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
