Veneto is the most populous and largest producer of controlled denomination of origin (DOC) of the three regions. Although the Tre Venezie collectively produce more red than white wine, the Veneto region produces more whites with DOC and in particular hosts Prosecco and Soave wines. The region is protected by the harsh northern European climate of the Alps, whose slopes form the northern extremes of the Veneto. These colder climates adapt well to white varieties such as Garganega (the main grape for Soave wines), while the warmer plains of the Adriatic coast, the river valleys and the area of Lake Garda are the places where they are produced the renowned red DOC Valpolicella, Amarone and Bardolino. In Veneto, two different wine areas are clearly distinguishable: an eastern part, near the Venice Lagoon between the Treviso hills, the Piave river plain and the Adriatic coast, where it is typical to produce the famous Prosecco (Glera), and other varieties are cultivated as Merlot, Carmenere, Verduzzo, Raboso Piave, Refosco, Tocai, Verdiso, Marzemino; and the western part, near Lake Garda and the city of Verona, famous for the wines based on varieties Corvina, Rondinella, Garganega, Trebbiano di Soave and Oseleta. In the central part of Veneto the enological transitions between the varieties and styles of the eastern and western parts. In that area you can find the Euganean Hills, the hills near Padua, which is a special Mediterranean microclimatic area; it is also famous for the production of orange blossom Moscato, a dessert sparkling wine. Another area in central-northern Veneto, near Asiago, is Breganze, where the Torcolato dessert wine is produced with the Vespaiolo grape.
