The white grape variety (also known as Geisenheim 11-34, Hochkroner) is a new breed between Riesling x Silvaner, which was confirmed by DNA analyses published in 2012. This is based, however, on only 20 DNA markers (see under molecular genetics). The naming was done after the Oranienstein Castle near Diez on the Lahn in Rhineland-Palatinate. With the same parents, Multaner, Osteiner, and Rieslaner were also created. The crossing took place in 1985 at the Geisenheim Research Institute in the Rheingau. The vine produces strong white wines with lemon aroma. However, it has not established itself in Germany. In 2016, only 2 hectares were recorded in Canada (Kym Anderson Kym).
