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, genes of Vitis amurensis and Vitis vinifera are included. The hybrid was crossed in 1991 by the breeder Valentin Blattner in Soyhières in the Swiss canton of Jura. The selection was then made at the Freytag 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 produces deep dark red wines with aromas of blackberries, blackcurrants(cassis), black pepper and dark chocolate with hints of cigar, leather and cedar wood. The variety is grown in small quantities in Switzerland and Germany (e.g. Weingut Galler Ansgar in the Palatinate). However, no stocks were reported in 2010 (statistics Kym Anderson).
