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 Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
