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. It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1989 by the vineyard owner Valentin Blattner in Soyhières in the Swiss canton of Jura, then selected in 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 yields floral 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. However, no stock was reported in 2016 (Kym Anderson).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
