Bivio Prosecco Vino Spumante Brut Sparkling wine is made from 100-percent Glera grapes from the Veneto region of northeastern Italy and is now available in a 187 ml format. The brut is also available in its original 750 ml size. Crafted by winemaker Marco Galeazzo, Bivio Prosecco is fresh and dry, with a fruity and floral fragrance, acidity to balance the residual sugars, and persistent bubbles.
