DOC - Designation of Controlled Origin
Denominazione di Origine Controllata (Designation of Controlled Origin) indicates a category of wines whose production is bounded to a particular area, a particular grape variety, territory of cultivation, yield grapes, production, ageing technologies and distinctiveness of the finished product.
The DOC can be divided into three sub categories:
Classico (Classic). This indicates wines of ancient production.
Riserva (Reserve). It indicates wines subjected to a longer than normal ageing period.
Superiore (Superior). It indicates wines with distinctive features such as a higher alcohol content due to higher sugar concentration.
An European law of the 2010 established that all products, including wines, must be identified with the DOP (Protected Designation of Origin - PDO) brand. Thus the DOC brand is no longer applicable and shouldn't be found on wine labels.
