The white grape variety is a new variety between(Silvaner x Riesling) x (Riesling x Silvaner). Synonyms or breeding number are Geisenheim 341-58 and Precocisima. The crossing was made in 1952 by Dr. Helmut Becker (1927-1990) at the Geisenheim Research Institute (Rheingau). The plant variety protection was granted in 1997. The late ripening, frost hardy vine is resistant to both types of mildew, which is why it is considered a PIWI variety, but susceptible to botrytis. It produces fruity, racy wines that are well suited as base wines for sparkling wines. No stocks were reported in 2010 (Statistics Kym Anderson).
