This red grape variety originates from the border region between Switzerland and Italy. Synonyms are Bailloz, Blue Savoy Grape, Cornalin, Cornalin du Valais, Hell Wine, Landroter, Rouge du Valais Vin d'Enfer. Already in 1903, the French ampelographer Adrien Berget suspected that the origin of the variety lies in the neighbouring Italian Aosta Valley. According to DNA analyses carried out in 2003, it originates from a presumably natural cross between the Aosta Valley varieties Petit Rouge x Mayolet. The variety is a parent of Cornalin (Cornalin d'Aoste, Humagne Rouge), which is often confused with it, as well as Goron de Bovernier, Neret di Saint-Vincent and Roussin. There is also a close relationship with the Vien de Nus variety. It arrived in Valais from the Aosta Valley a long time ago. It is one of the oldest varieties in Switzerland and has been cultivated here for centuries (it has disappeared in its country of origin). There, it is counted among the old-growth grape varieties.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".Prof. Dr. Walter Kutscher
