The white grape variety is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. Synonyms are VB 11-11-89-12 and Valentin Blattner 11-11-89-12, genes of Vitis amurensis and Vitis vinifera are included. The hybrid was crossed in 1989 by the owner of the vineyard Valentin Blattner in Soyhières in the Swiss canton of Jura. The selection was made at the Freytag nursery in Neustadt/Lachen-Speyerdorf in the Palatinate (Germany). The early ripening vine is resistant to frost and both types of mildew, but susceptible to botrytis. It produces flowery white wines with mild acidity, as well as aromas of apples, apricots and white flowers. The variety is grown by a producer in Groesbeek in the Netherlands. In 2016, however, no stock was declared (Kym Anderson).
