The white grape variety comes from France. Synonyms are Molette Blanche, Molette de Seyssel and (wrongly and confusingly) Mondeuse Blanche. It must not be confused with the Cacaboué, Jacquère or Mondeuse Blanche varieties, despite the fact that synonyms or morphological similarities seem to indicate this. A comparison of the DNA profiles has refuted the assumption that it is a mutation of the variety Roussette Basse, which is no longer cultivated. According to DNA analyses carried out in 2013, it is a presumably natural cross between Gringet x Gouais Blanc (Heunisch).
The medium to late-maturing, 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 Savoy, where it is still permitted in sparkling wine today. The area under cultivation in 2010 was 29 hectares.
