The red grape variety is a new breeding between unknown parents. The crossing took place at the Agroscope Changins-Wädenswil Institute (also RAC for short - hence the name) in Switzerland. The early to medium ripening vine has good resistance to various vine diseases, but is susceptible to downy mildew. It yields dark-coloured red wines. The variety is cultivated by one producer in the canton of Zurich. No stocks were reported in 2016 (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.Andreas Essl
