The red grape variety originates from France. Synonyms are Rouge de Diolly, Salagnin and Sasteigne. It was originally cultivated in the Département Drôme in the Rhône Valley and was thought to be extinct. In the 1920s, the vine was discovered by the Swiss vine grower Dr Henri Wuilloud (1921-1963) near the municipality of Diolly in the canton of Valais and was initially named Rouge de Diolly after the place where it was found.

According to DNA analyses carried out in 2013, it is a presumably natural cross between the varieties Mondeuse Blanche (white) x Tressot Noir (red). However, this is based on only 20 DNA markers (see molecular genetics). Robin Noir was a crossing partner in the new variety Diolinoir.

For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
