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 which is in the province of Trieste, Italy. It is made from the Prosecco grape 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, but a still wine 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 a UNESCO World Heritage Site, in large part due to the region's role in the production of Prosecco. Since 2020, the DOC rules allow a rosé variety of Prosecco designated spumante rosé, which must contain Glera blended with 10–15% Pinot noir.
