The red grape variety (also VB 91-26-19) is an interspecific new variety; the crossing took place in 1991 by the breeder and vineyard owner Valentin Blattner in Soyhières in the Swiss canton of Jura, the selection then in the Freytag vine nursery in Neustadt/Lachen-Speyerdorf in the Palatinate (Germany). For a long time, a cross between Pinot Noir x unknown resistance partners was stated. The breeder himself, however, announced that a complex cross Cabernet Sauvignon x (Silvaner x (Riesling x Vitis vinifera) x (JS 12417 x Chancellor) was the basis; as is also the case with his two new varieties Cabernet Blanc and Cabertin. Accordingly, genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera would be included. The medium ripening vine is resistant to both powdery mildew, botrytis and frost. It yields a ruby-coloured red wine with aromas of black cherries. In 2016, an area of 0.2 hectares was designated in Switzerland (Kym Anderson statistics). Small populations are also said to exist in Germany.
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.
