The red grape variety (also FR 437-82 r) is a new variety between Cabernet Sauvignon x(Merzling x(Zarya Severa x Muscat Ottonel)). In some sources this is indicated in the form Cabernet Sauvignon x Solaris; the father variety later became the Solaris variety. There are 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 Freiburg (Baden-Württemberg). Incidentally, the new Cabernet Carol variety was created with the same parents. This early-ripening vine is resistant to botrytis and downy mildew, but is particularly susceptible to powdery mildew. It produces colour-intensive, extract- and tannin-rich red wines similar to Cabernet Sauvignon. In Germany it is mainly grown in the Baden region (34 ha) and in Switzerland (4 ha). Small stocks are also said to exist in Italy and Denmark. In 2016, a total of 38 hectares of vineyard area were designated (statistics Kym Anderson).
