The red grape variety (also FR 377-83 R) is a new variety between Cabernet Sauvignon x (Merzling x (Zarya Severa x St. Laurent)). This is also given in the form Cabernet Sauvignon x Bronner, as the father population was given the variety name Bronner. It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1983 by Norbert Becker (1937-2012) at the Freiburg Institute of Viticulture.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
