Denominazione di origine controllata (DOC; pronounced [denominatˈtsjoːne di oˈriːdʒine kontrolˈlaːta]; English: controlled designation of origin) is a quality assurance label for Italian wines. The system is modeled on the French Appellation d'origine contrôlée (AOC) designations. The Italian government introduced the system in 1963 and overhauled in 1992 to comply with European Union law on protected geographical designations of origin, which came into effect that year.
