The red grape variety is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. Synonyms are Cabernet Noir, VB 91-26-04 and Valentin Blattner VB 91-26-04. It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1991 by the vineyard owner Valentin Blattner in Soyhières in the canton of Jura in Switzerland. The early-maturing, loose-grained and frost-hardy vine is resistant to both powdery mildew and botrytis, which is why it is considered a PIWI variety. It produces red wines with soft tannins and diverse aromas of dark cherries, juniper berries, violets, cloves and pepper. The variety is cultivated by one producer in small quantities in the Swiss canton of St. Gallen (3 ha), in Belgium, England and in the Netherlands. In 2016, however, only the stock in Switzerland was reported (statistics Kym Anderson).
