Producers classify Prosecco as a sparkling wine. To make Prosecco, they use the Charmat method, also known as the tank method, which involves conducting the second fermentation in large stainless steel tanks rather than in the bottle used to produce Champagne. The Charmat method allows for a quicker and less expensive production process than Champagne’s traditional method. Producers can make Prosecco in various styles, from brut (dry) to extra dry (slightly sweet), and they typically serve it chilled.
