The red grape variety (also FR 455-83 R) is a new variety between Cabernet Sauvignon x(Merzling x(Zarya Severa x St. Laurent)). It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. From the father variety later on the variety Bronner was developed. The hybrid was crossed in 1983 by Norbert Becker (1937-2012) at the Institute of Viticulture in Freiburg. The late maturing vine is resistant to both types of mildew and is considered a PIWI variety. It produces colour-intensive, tannin-rich red wines. It is cultivated in small quantities in the Baden region (1 ha) and in the Swiss canton of Schaffhausen (0.1 ha). In 2016, a total of 1.1 hectares of vineyard area was designated (Kym Anderson).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
