The white grape variety (also VB 91-26-1) is an interspecific new variety between Cabernet Sauvignon x Regent. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1991 by the vineyard owner Valentin Blattner in Soyhières in the Swiss canton of Jura and then selected at vine nursery Freytag in Neustadt/Lachen-Speyerdorf in the Palatinate(Germany).

The early to medium-ripening vine is resistant to frost, botrytis and both types of mildew, but tends to produce small berries (millerandage). It produces aromatic, fragrant white wines similar to Sauvignon Blanc.
