The white grape variety (also Geisenheim 11-34, Hochkroner) is a new breed between Riesling x Silvaner, which was confirmed by DNA analyses published in 2012. However, this is based on only 20 DNA markers (see molecular genetics). It was named after the castle Oranienstein near Diez an der Lahn in Rhineland-Palatinate. By the way, the varieties Multaner, Osteiner and Rieslaner were created with the same parents. The crossing was made in 1985 at the Geisenheim Research Institute in the Rheingau. The vine produces strong white wines with lemon aroma. However, it has not become established in Germany. In 2016 only 2 hectares were recorded in Canada (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.Sigi Hiss
