This white grape variety comes from France. The name is derived from the rust-red (roux) coloured berries. Synonyms are Barbin, Bergeron, Courtoisie, Fromental, Fromental Jaune, Fromenteal, Fromenteau, Greffon, Greffou, Martin Cot, Martin Rot, Petite Roussette, Picotin Blanc, Plant de Seyssel, Rabellot, Rabelot, Ramoulette, Rebellot, Remoulette, Rosana, Roussane, Roussanne Blanc, Roussette, Rusan, Rusan Belyi and Rusan Blan.Despite seemingly suggestive synonyms or morphological similarities, it must not be confused with the varieties Altesse, Courbu Blanc (Courtoisie), Gringet, Marsanne, Rosé du Var (Roussanne du Var) or Roussette d'Ayze. According to DNA analyses, there is a parent-offspring relationship with the Marsanne variety. However, the exact parentage is unknown.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
