The Verdiso grape is believed to be a native variety of the Euganean Hills, although it has since disappeared from that region. From the early 18th century, Verdiso became established in the Conegliano-Valdobbiadene area, where it was favored for its high productivity, even if this came at the expense of must quality.
Today, Verdiso remains a key supporting grape in blends - particularly with Prosecco (Glera) - as well as with other local varieties. Its high natural acidity makes it especially suited for drying, and it plays an important role in the production of the Colli di Conegliano DOCG Torchiato di Fregona, a passito-style wine.
Verdiso berries are white, medium-large, and ellipsoidal, with thin, waxy, greenish-yellow skin. The bunch is medium-sized, pyramidal and winged, while the leaf is medium, pentagonal, entire or three-lobed.
The vine is known for its good vigor, late ripening, and consistent, abundant yields. Wines produced from Verdiso are straw yellow in color, with intense, fruity aromas. On the palate, the wine is fresh, harmonious, and light in body, with modest persistence. It is primarily vinified in blends, especially in the Conegliano-Valdobbiadene Prosecco area.
