The red grape variety is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. Synonyms are Cabernet Jura 5-02, Valentin Blattner 5-02 and VB 5-02. It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1991 by the breeder and vineyard owner Valentin Blattner in Soyhières in the Swiss canton of Jura, and the selection was made in the Freytag nursery in Neustadt/Lachen-Speyerdorf (Palatinate, Germany). The medium-maturing, frost-hardy vine is resistant to both powdery mildew and botrytis, which is why it is considered a PIWI variety. It produces colour-intensive, aromatic red wines with a discreet muscat tone. In 2016, 27 hectares were designated in Switzerland (Kym Anderson); small stands also exist in Germany and Austria.
