The white grape variety comes from France. Synonyms are Groslot de la Thibaudiere and Groslot Gris. It is a colour mutation of the Grolleau Noir variety. The medium maturing vine is susceptible to botrytis. In the Loire Valley, it is mainly used as a blend with other varieties for IGP Val de Loire wines. In 2010, 451 hectares of vineyards were designated, with a sharp downward trend (ten years earlier, it was twice as much).
