The white grape variety originates from France. Synonyms are Molette Blanche, Molette de Seyssel and (erroneously and confusingly) Mondeuse Blanche. It should not be confused with the varieties Cacaboué, Jacquère or Mondeuse Bl anche, despite seemingly suggestive synonyms or morphological similarities. By comparing the DNA profiles, the assumption that it is a mutation of the no longer cultivated variety Roussette Basse was refuted. According to DNA analyses carried out in 2013, it is a presumably natural cross between Gringet x Gouais Blanc (Heunisch). The medium to late ripening, high-yielding vine is susceptible to downy mildew and botrytis. It produces light-coloured white wines rich in alcohol and acidity. The variety was first mentioned in 1876 by the two French ampelographers Victor Pulliat (1827-1896) and Alphonse Mas as a variety of the Seyssel area in Savoie, where it is still permitted in sparkling wine. In 2016, 18 hectares of vines were designated (Kym Anderson).
