The red grape variety (also FR 437-82 r) is a new variety between Cabernet Sauvignon x (Merzling x (Zarya Severa x Muskat-Ottonel)). In some sources, this is given as Cabernet Sauvignon x Solaris; the Solaris variety later emerged from the father variety. It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1982 by Norbert Becker (1937-2012) at the State Viticulture Institute in Freiburg (Baden-Württemberg). Incidentally, the same parents were also used to create the new Cabernet Carol variety. The early-maturing vine is resistant to botrytis and downy mildew, but susceptible to powdery mildew. It produces intensely coloured red wines rich in extract and tannins, similar to Cabernet Sauvignon. It is cultivated in Germany (34 ha), Switzerland (4 ha) and the Czech Republic (34 ha). Small populations are also said to exist in Italy and Denmark.
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.
