Native to Southwest France, Valdiguié also maintains a fairly substantial history in California. Given its high-yielding capacity, Valdiguié became very popular during the Prohibition. Until 1980, Californians called it Napa Gamay because of its similarities to Gamay as a finished wine. But in that year, a French ampelographer, Pierre Galet correctly identified it as Valdiguié—not Gamay. Today it still grows in pockets of respected appellations throughout the state. Somm Secret—In France it is also called Gros Auxerrois.
