Prosecco is a type of sparkling wine, made with grapes from the Conegliano Valdobbiadene region in Veneto, Italy. In order for a sparkling wine to be considered Champagne, it must come from the Champagne region of ​France. Champagne tends to have much smaller bubbles than Prosecco, as well as bready, yeasty, crème brûlée flavors.
