The red grape variety (also FR 484-87 r) is a new variety between (Joannes Seyve 23-416 x Pinot Noir) x (Merzling x (Zarya Severa x St. Laurent)). This is also indicated in the form Freiburg 4-61 x Freiburg 236-75 r or also Bronner. Because from the sire's variety the variety Bronner came out later by selection. Due to the numerous involved varieties, which were also products of crossings, genes of Vitis aestivalis, Vitis amurensis, Vitis cinerea, Vitis labrusca, Vitis lincecumii, Vitis riparia, Vitis rupestris and Vitis vinifera are included. The crossing of the hybrids was carried out in 1987 by Norbert Becker (1937-2012) at the State Viticulture Institute Freiburg. The early to medium maturing vine is resistant to frost and downy mildew, but susceptible to powdery mildew and botrytis. It produces colour-intensive, tannin-rich red wines. In Germany, it is cultivated on 13 hectares in the Baden and Rheinhessen growing regions. There are also small stocks in Switzerland (1 ha) and Italy. In 2016, a total of 14 hectares of vineyards were designated (Kym Anderson).

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.
