Prosecco is produced exclusively in north east Italy. Its story began in the area of Conegliano Valdobbiadene over three centuries ago, where the highest quality, Prosecco Superiore, is still produced to this day. A level of quality that in August 2009 was awarded the DOCG, rightly placing Prosecco among truly great wines of Italy.
Under the new system, the historic Prosecco Doc (Conegliano Valdobbiadene and Colli Asolani) have become DOCG, while the areas of northeast Italy that used to make Prosecco Igt can now make the base DOC. The result is that there are now two levels of Prosecco on the market: the DOCG, the peak of the quality pyramid, representing by the Conegliano Valdobbiadene denomination, with its 15 hill municipalities, and the DOC base, covering the provinces of Treviso, Belluno, Venice, Padua, Vicenza, Udine, Pordenone, Trieste and Gorizia, a broad denomination made up of more than 600 munipalicities in Veneto and Friuli.
The DOCG zone is in province of Treviso, stretching over the hills between the small towns of Conegliano and Valdobbiadene, 50 km from Venice and around 100 km from the Dolomites. The hills chains stretch from east to west, from the flat plain to the foothills of the Alps.
