The red grape variety (also FR 377-83 R) is a new variety between Cabernet Sauvignon x(Merzling x(Zarya Severa x St. Laurent)). In some sources this is referred to as Cabernet Sauvignon x Bronner, because the Bronner variety was later selected from the father population. There are genes of Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1983 by Norbert Becker (1937-2012) at the Viticulture Institute Freiburg. The medium to late ripening vine is resistant to downy mildew and frost. It produces colour-intensive, tannin-rich red wines. The variety is cultivated in Germany in the Baden and Württemberg (10 ha) and in Switzerland (1 ha) growing regions. In 2016, a total of 11 hectares of vineyard area were designated (statistics Kym Anderson).
