What is the apex quality designation subjecting Prosecco production to Italy’s strictest regulations?

Answer

Denominazione di Origine Controllata e Garantita (DOCG)

Italy formalizes quality control through a hierarchy of designations. While Prosecco DOC covers a broad growing zone with more flexible yield rules, the highest echelon of quality resides within the Denominazione di Origine Controllata e Garantita, commonly abbreviated as DOCG. Wines from DOCG areas are subjected to Italy’s most stringent regulations regarding grape growing, including restrictions that often necessitate lower yields, such as those found in hillside vineyards. The Conegliano Valdobbiadene Superiore DOCG is cited as the most celebrated example of this top-tier classification.
