Also known as Bergeron in the french Savoie region. Semi-classic grape grown in the Hermitage-Rhone and southern Cotes du Rhone region of France. Still occasionally incorporated into white wine blends, (e.g: with the Marsanne grape wine), because of its acidity and aroma but finding less and less favor.
