Veneto is among the foremost wine-producing regions, both for quality and quantity. The region counts over 20 DOC zones and a variety of sub-categories, many of its wines, both dry and Spumanti, are internationally known and appreciated. The three most well known DOCs are Bardolino, from the town with the same name and surrounding the shores of Garda Lake, Valpolicella, and Soave. Other noteworthy wines produced here are the white Bianco di Custoza, the excellent sparkling Prosecco, the Breganze, and the Amarone (a rich and powerful red from the Verona province). If you travel to the Treviso area, look for the little-known Clinton, a wine that is banned from distribution because it does not conform to the DOC standards, but is produced in limited quantities for local consumption. The importance of winemaking in this region is underscored by the creation in 1885 of the very first Italian school for vine growing and oenology. In addition, Veneto was the first region to constitute the first strada del vino or "wine road". This first wine-touring road featured special road signs providing information on vines and the wines they were made into and joined the Valdobbiadene and Conegliano DOC zones crossing a series of hilly vineyards. The most appreciated wines in the region come from the provinces of Treviso, Verona, Padova, Venice, and Vicenza. The area around Verona, with its temperate climate and hilly surrounding, is believed to have cultivated grapes since the Bronze Age.
