DOC classification (Controlled Designation of Origin) refers to areas traditionally qualified for producing quality wines, which, before achieving this recognition, have been classified IGP for at least 5 years. DOC wines must also express a particular characteristic that is strongly tied to the territory where the grape is cultivated, as well as respect all the regulations of reference during all the production phases.
DOCG designation (Controlled and Guaranteed Designation of Origin) is reserved for wines that have been classified as DOP (Protected Designation of Origin) for at least 10 years. Only these wines boast a particular and concrete prestige, as well as being recognized as quality wines by a sensory assessment. The regulations that must be followed in order to obtain DOCG classification set forth procedures and controls during the entire production cycle from the vineyard to the bottle.
For DOP and DOCG wines, there are also other specifications: Classico (indicates that the wine has been produced in a subzone of a DOP or DOCG area), Riserva (attributed to DOP or DOCG wines that have been aged longer than their regulations set forth) and Superiore (identifies DOP or DOCG wines for which a yield per hectare under at least 10% of what is set forth by the regulations is established).
