The D.O.C.

Controlled Designation of Origin

D.O.C. is the acronym of "Denominazione di Origine Controllata", Controlled Designation of Origin, a label certifying both the vine variety's area of origin and the quality of winemaking and bottling techniques of the wine bearing such a designation; it is then used to indicate a produce of reputed quality, whose properties are typical of a specific geographical location and winemaking process according to a specific regulation approved by Ministerial Decree.
Wines before being distributed under the D.O.C. label undergo chemical, physical and sensory analyses certifying the requirements provided for by the winemaking regulations.
A higher category in terms of quality of production and grapes used has been recently identified within the D.O.C. seal with the acronym D.O.C.G., “Denominazione di Origine Controllata” (Controlled and Guaranteed Designation of Origin), where the term “Garantita" (Guaranteed) identifies a wine as being typically produced in a specific terroir by some designated wineries.
The I.G.T. designation, "Indicazione Geografica Tipica" (Typical Geographical Indication), specifically identifies the vine variety from a typical region or geographical area, regardless of the production method used.
