The red grape variety (also VB 91-26-19) is an interspecific new variety; the crossbreeding was carried out in 1991 by the breeder and winery owner Valentin Blattner in Soyhières in the Swiss canton of Jura, the selection then at the Freytag Vine School in Neustadt/Lachen-Speyerdorf in the Palatinate (Germany). For a long time, a cross between Pinot Noir x unknown resistance partners was indicated. The breeder himself, however, announced that a complex cross between Cabernet Sauvignon x (Silvaner x (Riesling x Vitis vinifera) x (JS 12417 x Chancellor)) was the basis; as 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 types of mildew, botrytis and frost. It produces a ruby red wine with aromas of black cherries. In 2016, an area of 0.2 hectares was designated in Switzerland (statistics Kym Anderson). Small stocks are also expected to be found in Germany.
