The white grape variety (also FR 493-87) is a new variety between Solaris x Gelber Muskateller. It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1987 by Norbert Becker (1937-2012) at the Viticulture Institute Freiburg (Baden-Württemberg). The medium-early maturing vine is resistant to both types of mildew and frost. It produces acidic white wines with an intense muscaty tone. The variety was released as a quality wine grape variety in Austria around 2018 after a long period of testing. In 2016, four hectares of vineyards were designated in Switzerland (e.g. Schaffhausen, Zurich) (Kym Anderson).
