The white grape variety is a new variety between Orangetraube x Welschriesling. Synonyms are Klosterneuburg 16-8 and Orangeriesling. The cross was made by Dr Friedrich Zweigelt (1888-1964) in 1922 at the Klosterneuburger Weinbauinstitut(Lower Austria), as indicated by the second part of the name.

The medium-ripening vine is susceptible to powdery mildew. It produces full-bodied and extract-rich, rather neutral-tasting white wines with moderate acidity, which are predominantly vinified sweet. The variety is also used as table grape.

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
