The Gregoletto family can look back on a long vine growing and winemaking history evidenced by several historic documents showing that already at the beginning of the 17th century the family cultivated vines in the hills of Premaor di Miane. That history is highlighted, too, by the historic 17th century building that until today houses the estate's cellars.

The family's winemaking activity got an even greater impulse after WWII, when Luigi Gregoletto began to produce wines that emphasize their origin by following strict quality rules.

Today the estate's vineyards extend over 11 ha of hillside vineyards in the villages of Miane, San Pietro di Feletto and Refrontolo. During harvest the picking of the grapes is exclusively done by hand and in several triages by which only fully ripe grapes are selected. The bunches are pressed during the day and the musts of each single vineyard and parcel is fermented separately.

During the following spring the Prosecco is bottled in three different versions: as a still wine, which the Gregolettos have always considered the 'family gem', as a sparkling, Extra Dry wine and as a historic frizzante.

The frizzante is the result of the 'Metodo Ancestrale', a natural refermentation in bottle, which remains undisgorged.
Except for Prosecco the estate produces the rare white Verdiso dei Colli Trevigiani IGT and it has been one of the first and one of the very few to produceManzoni Bianco dei Colli Trevigiani IGT. Additionally Gregoletto produces a Merlot dei Colli Trevigiani IGT, a Cabernet del Colli Trevigiani IGT, a Colli di Conegliano DOCG both white and red, and Grappa di Prosecco, an acquavite made from the pomace of the Prosecco grapes.

On appointment all the wines can be tasted in the tasting room and visits can be made to the cellar as well as the library, which houses historic documents and books on winemaking and viticulture.
