Denominazione di Origine Controllata (D.O.C.) :
The Italian system for defining wine regions and wine names. In addition, the D.O.C.G. (Denominazione di Origine Controllata Garantita) covers regions willing to submit their wines to tougher requirements, including tasting approval.
Defines the area where a wine's grapes were grown, such as Bordeaux, Gevrey-Chambertin, Alexander Valley or Russian River Valley. Regulations vary widely from country to country. In order to use an appellation on a California wine label, for example, 85 percent of the grapes used to make the wine must be grown in the specified district.
