The white grape variety comes from France. Synonyms are Aigre Blanc, Blanc Aigre, Blanchette, Couilleri, Dongine, Jongin, Jonvin, Molette and Savouette. It must not be confused with the varieties Molette (Mondeuse Blanche), Roussette d'Ayze or Verdesse (Dongine), despite the fact that synonyms or morphological similarities seem to indicate this. According to DNA analyses carried out in 2000, a presumably natural cross between Mondeuse Blanche and Dureza gave rise to the variety Syrah. There are also parent-offspring relationships between Mondeuse Blanche and the varieties Mondeuse Noire, Robin Noir and Viognier (this has refuted the long-standing assumption that Mondeuse Blanche is a mutation of Mondeuse Noire). The late ripening, low-yielding vine is somewhat susceptible to botrytis. It produces acidic, alcohol-rich white wines with storage potential. The variety is approved in the Savoy region in the Bugey and Vin de Savoie areas and occupies four hectares in France. In Switzerland it is cultivated on three hectares. In 2016, a total of seven hectares of vineyards were designated (Kym Anderson statistics).
