Prosecco is an Italian DOC or DOCG white wine produced in a large area spanning nine provinces in the Veneto and Friuli Venezia Giulia regions, and named after the village of Prosecco. It is made from the Prosecco grape (renamed Glera in 2009 within the European Union) but denomination rules allow up to 15% of the wine to be other permitted varieties. Prosecco is almost always made in sparkling or semi-sparkling style (spumante and frizzante, respectively), but a still wine (tranquillo) is also permitted. Within the larger designation are two small DOCG areas, Conegliano Valdobbiadene Prosecco in the hills between the towns of Conegliano and Valdobbiadene, and Asolo Prosecco around the nearby town of Asolo. Prosecco Superiore is always spumante and comes only from these DOCG areas.
In 2019, Le Colline del Prosecco di Conegliano e Valdobbiadene became an UNESCO World Heritage Site, in large part due to the region’s role in the production of Prosecco.
