Nine provinces guard a true natural treasure. It is a land with a climate protected by the Alps and mitigated by the Venice Lagoon, where vine growing goes back to time immemorial. The grape variety Glera, the base for Prosecco wine, finds its genuine expression here. Il Colle winery, particularly well known for its Prosecco Superiore DOCG and Cartizze wines, is located in San Pietro di Feletto in the province of Treviso. The estate lies between the municipalities of Conegliano and Valdobbiadene, historically the best area for producing Glera grapes, so the Prosecco produced here is of superior quality. In 2009 this area and its wines were awarded the title Conegliano – Valdobbiadene Prosecco Superiore DOCG: an appellation of quality certifying the Registered and Guaranteed Designation of Origin of the Prosecco produced here. Il Colle is one of the long-standing wineries in the area which has earned itself this prestigious title. Cartizze: superior sparkling wine The finest product comes from the Cartizze area, which is limited to just 100 hectares. It is where a temperate microclimate meets an ancient soil to produce the famous Superiore di Cartizze, our flagship product. Man has been making wine in this area for centuries alongside an unparalleled wealth of culture, history, art, food and wine. The Prosecco Superiore DOCG terroir has been recognised as one of the most important winemaking areas in Italy and has been nominated as a UNESCO heritage site. Il Colle has always believed in the importance of local ties, of working with the local people and reciprocal loyalty. For the past 35 years it has collaborated with a group of just over 50 small producers who still harvest their grapes in a healthy, traditional manner.
