Italian wine law follows the European DOP/IGP system: IGT corresponds to IGP, while DOC and DOCG are traditional Italian designations within the higher DOP category, with DOCG generally requiring stricter controls and certification.
Each appellation’s disciplinare defines its production area, permitted grapes, yields, winemaking and aging requirements, while terms such as Classico, Superiore, and Riserva carry specific legal meanings within individual denominations.
