Technically speaking, Prosecco is a sparkling wine that originates from the Valdobbiadene region in Veneto, Italy (although it’s also made in other parts of Italy including Friuli-Venezia Giulia). The wine is made with Prosecco grapes (aka Glera) and made into wine via the Charmat sparkling method, which gives wines approximately 3 atmospheres of pressure. This means Prosecco’s bubbles typically last longer than beer (which has approximately 1.5 atmospheres of pressure) and not usually as long as Champagne (5-6 atmospheres of pressure).
Most Prosecco wines are produced in a dry, brut style. However, due to the grapes’ fruity flavors of green apple, honeydew melon, pear, and honeysuckle, it usually seems sweeter than it is.
