This red grape variety originates from the border region between Switzerland and Italy. Synonyms are Alter Walliser, Bailloz, Blaue Savoyertraube, Completer, Cornalin, Cornalin du Valais, Gros Rouge du Pays, Höllenwein, Landroter, Neyrum, Petit Rouge du Valais, Rouge du Valais, Vieux Rouge du Valais, Vin d'Enfer and Walliser Landroter.

The variety is one of the oldest grape varieties cultivated in Valais; it was already known as Neyrum at the beginning of the 14th century. The French ampelographer Adrien Berget already suspected in 1903 that the variety originated in the neighbouring Italian Aosta Valley. From the middle of the 19th century, it was increasingly replaced by the Pinot Noir and Gamay varieties and was almost extinct by the middle of the 20th century.
