The Denomination of Controlled Origin (DOC), obtained in 2009, refers to the production regulations which form the basis for Prosecco DOC and which precisely define the characteristics that this wine must have.
We summarise here some key aspects of these regulations here.

Types: Semi-sparkling, Sparkling, and Still Prosecco

Wording: Prosecco DOC is the main denomination. 

The special mention of Treviso and Trieste can be given if grape harvesting, wine-making and bottling take place entirely within one of these two provinces.

Production area: in the provinces of Belluno, Gorizia, Padova, Pordenone, Treviso, Trieste, Udine, Venezia, and Vicenza.
