Il Colle winery, particularly well known for its Prosecco Superiore DOCG 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.
Il Colle has access to 120ha of vineyards. 26ha are directly owned by the family. 8ha are 100% organic.
