Wines from Livorno Province - What do DOC and DOCG mean?
The letters DOC or DOCG on an Italian wine label mean Denominazione di Origine Controllata, and Denominazione di Origine Controllata e Garantita, the latter superior to the first. They refer to government guarantees of the wines’ origins.
About 300 wine growing regions in Italy have the DOC designation, while only 21 have a DOCG label. The DOCG wines conform to DOC laws and in addition are quality tested by government-appointed inspectors.
