The white grape variety is a new breeding between (Silvaner x Riesling) x (Riesling x Silvaner). Synonyms or breeding numbers are Geisenheim 341-58 and Precocisima. The cross was made in 1952 by Dr. Helmut Becker (1927-1990) at the Research Institute Geisenheim (Rheingau). Plant variety protection was granted in 1997. The late-maturing, frost-hardy vine is resistant to both types of powdery mildew, which is why it is considered a PIWI variety, but susceptible to botrytis. It yields fruity, racy wines that are well suited as base wines for sparkling wines. No stocks were reported in 2016 (Kym Anderson).

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
