Prosecco DOC refers to the wine with Controlled Designation of Origin status. The production area of Prosecco DOC is located in the northeast region of Italy, including five provinces in Veneto and four provinces in Friuli Venezia Giulia. These areas are characterized by mild climates, sufficient rainfall, and alluvial soils rich in minerals. Prosecco DOC can be further divided into DOC Veneto, DOC Marca Trevigiana, and DOC Colli Trevigiani, depending on the production area. The grapes used for making Prosecco DOC must be harvested and the wine produced and bottled exclusively within the specified region.
