Since 2019 the Prosecco Hills of Conegliano and Valdobbiadene are a World Heritage Site, the 55th Italian site recognized by Unesco. Thus the universal value of a real cultural landscape is recognized where the work of the winegrowers has helped to create a unique scenario.
The grape used for the production of Prosecco is Glera, a variety typical of northeastern Italy since the Roman age, making up at least 85% of the blend. The percentage can be completed by the native grapes Glera Lunga, Verdiso, Perera, Chiaretta and other types of white grapes determined by the disciplinary.
Within the area of DOC Prosecco, comprising nine provinces between Veneto and Friuli Venezia Giulia, is the historic area of the Province of Treviso where Casa Gheller has its headquarters and has been producing its wines for generations. In the hilly area of the Marca Trevigiana there are the Superior sub-areas of Asolo DOCG and Conegliano Valdobbiadene DOCG where aromas and fragrances are enhanced by the peculiarities that the territory and microclimate give to the wine.
Summit of quality and golden synthesis of the Conegliano - Valdobbiadene appellation, at the apex of the Prosecco pyramid is the Cartizze. A sub-area governed since 1969 of only 107 hectares of vineyards between the steepest hills of San Pietro di Barbozza, Santo Stefano and Saccol, in the municipality of Valdobbiadene. A perfect combination of mild microclimate and very ancient soils that give Prosecco unique aromatic and sensory notes.
