The white grape variety is a new breed between Seyval Blanc x Zähringer. The true parentage was only determined by DNA analyses carried out in 2016; until then Cabernet Sauvignon x Bronner was accepted. It contains genes from Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1983 by Norbert Becker (1937-2012) at the Viticulture Institute in Freiburg (Baden-Württemberg). The medium-early ripening, frost-hardy vine is resistant to both types of mildew and, because of the loose berries, also to botrytis. Due to its resistance to fungus, it is considered a PIWI variety. The tendency to trickle is low. It produces strong, fruity white wines. The variety was released as a quality wine grape variety in Austria in 2018 after a long trial period and is also cultivated in Germany and Switzerland (3 ha). In 2016, however, only the Swiss stock was released (statistics Kym Anderson).
