Which classification denotes wines with less stringent regulations than DOCG?

The classification that denotes wines with less stringent regulations than DOCG is DOC, which stands for "Denominazione di Origine Controllata." This classification system was established to regulate the production of wines in Italy and ensures certain quality standards while allowing for greater flexibility than DOCG (Denominazione di Origine Controllata e Garantita).

DOC wines must meet specific criteria regarding grape varieties, geographical location, and production methods, but these criteria are generally less rigorous compared to those for DOCG wines. DOCG wines undergo a stricter series of rules, including mandatory aging requirements and tasting examinations, making them more exclusive. Therefore, DOC provides a broader framework that encourages a wider array of wines while still maintaining quality control.

IGT (Indicazione Geografica Tipica) represents a less regulated category that allows producers more freedom in grape choice and winemaking techniques, but it is even less stringent than DOC. The classifications of Riserva and Superiore are designations that refer to wines with additional aging or particular quality specifications within existing categories, but they are not separate classifications like DOC.
