Prosecco is a sparkling wine from north-eastern Italy, specifically the Veneto and Friuli-Venezia Giulia wine regions. It is also the informal name for the grape variety used to make these wines, which is now known officially as Glera. Until 2020 the designation applied only to white wine, but Prosecco Rosé was introduced in 2020.

Italian Prosecco was once a broad category of sweet fizz, bearing a strong resemblance to the low-quality Asti (then called Asti Spumante). It was seen to some degree as poor man’s champagne. It was used by wine educators to demonstrate the quality difference between sparkling wines made in the methode traditionelle and those made by the Charmat method.
