The Denominazione di Origine Controllata is a trademark of Italian origin that is used to describe a product of quality by certifying its area of origin and harvest. These wines, before being placed on the market, must undergo during production to a preliminary chemical–physical analysis and an organoleptic test certifying their compliance with the requirements of the specification; failure to comply with the requirements prevents the marketing with the DOC label. The classification by the acronym DOCG (Denominazione di Origine Controllata e Garantita) is at a higher level than the DOC.
