The winery owner Valentin Blattner from Soyhières in the canton of Jura(Switzerland) has been quite active as a private breeder since the 1980s. Crossbreeding was carried out on his farm, followed by selection and rearing, partly in the Freytag nursery in Neustadt/Lachen-Speyerdorf in the Palatinate(Germany). Great importance was attached to resistance to frost and fungal diseases, therefore mostly varieties of the species Vitis amurensis or with gene parts thereof were involved. These are therefore mostly PIWI varieties. However, it is unusual that the breeder does not name both parents, but only prominent varieties, such as the often involved Cabernet Sauvignon. Blattner created the new varieties Birstaler Muscat, Cabaret Noir, Cabernet Blanc, Cabernet Colonjes, Cabernet Early, Cabernet Foch, Cabernet Jura, Cabertin, Millot-Foch, Pinotin, Réselle, Riesel, Satin Noir, Sauvignac and VB 32-7. These varieties are partly grown in Belgium, Germany, Canada, the Netherlands, New Zealand, Austria and especially in Switzerland.
