The red grape variety is a new cross between Deckrot x Blauer Portugieser. The cross was made in 1972 at the Geisenheim Research Institute (Rheingau) by Dr. Helmut Becker (1927-1990). Externally, it is very similar to the father variety. The vine is resistant to frost and fungal diseases. The red-fleshed berries yield deep-dark red wines that are well suited as Teinturier (colouring wine). The variety is grown on 53 hectares in Germany (Baden, Rheinhessen, Pfalz) and on 15 hectares in Switzerland (Schaffhausen). In 2016, a total of 68 hectares of vines were designated (Kym Anderson).
As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.Hans-Georg Schwarz
