The white grape variety is a new breed between Kerner x unknown parent variety according to 2012 conducted DNA. The paternity indicated in the breeding list of Silvaner turned out to be incorrect. Synonyms are Jewel and Weinsberg S 378 (Jewel is also a synonym for the grape variety Frühgipfler). The crossing took place in 1951 by August Herold August (1902-1973) and Helmut Schleip at the State Teaching and Research Institute Weinsberg in Württemberg. The varietal protection was granted in 1987. The medium ripening grape varieties vine is resistance against downy mildew, but very susceptible to powdery mildew.
