The red grape variety comes from the Swiss/Italian border region. Synonyms are Cornalin, Cornalin du Valais, Landroter and Rouge du Valais. The French ampelographer Adrien Berget already suspected in 1903 that the origin of the variety was 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 the often confused Cornalin (Cornalin d'Aoste, Humagne Rouge), as well as of Goron de Bovernier, Neret di Saint-Vincent and Roussin. There is also a close relationship with the Vien de Nus variety.
