Montellini produces Prosecco in the Veneto region of Northern Italy, where the Prosecco designation centers on the Glera grape. The winery's Prosecco Treviso Brut, made from Glera, represents the dry end of the Prosecco spectrum—a style marked by crisp acidity and the delicate fruit character typical of the region. Prosecco from the Treviso area, where Montellini operates, tends toward mineral notes and subtle floral aromatics. The Prosecco Treviso Brut has been rated by Wine Spectator.
