Valdiguié
Valdiguié is a red wine grape grown primarily in the Languedoc-Roussillon region of southern France, where it is generally known by the alias Gros Auxerrois. In California it has been known as Napa Gamay or Gamay 15. Until 1980 Napa Gamay was believed to be the Gamay of Beaujolais, but following genetic analysis the name "Napa Gamay" has been banned from U.S. wine labels since June 23, 1997. Confusingly, both the Pinot noir clone Gamay Beaujolais and Valdiguié were sometimes also labelled as "Gamay Beaujolais" until that name was banned on labels in April 2007.
Other synonyms include Valdiguer, Cahors, Jean-Pierrou at Sauzet, Quercy and Noir de Chartres.
