Verduzzo Trevigiano is white Italian wine grape variety that is grown in the Veneto wine region of northeast Italy. For centuries it was thought to be a sub-variety of the Friuli-Venezia Giulia wine grape Verduzzo Friulano (commonly just called Verduzzo) but DNA profiling research in 2010 and 2011 defintely proved that Verduzzo Trevigiano was its own distinct variety.
The name Trevigiano means "from the province of Treviso" and the grape is today still widely found in the Treviso and Venezia province of the Veneto but ampelographers are not yet certain if the grape is, indeed, indigenous to the region. Anecdotal evidence speculates that the grape may have originated in Sardinia and was introduced to the region in the early 20th century but so far no DNA evidence has shown a link with any modern Sardinian grape varieties.
Verduzzo Trevigiano is known to be a vigorous vine that can adapt to many different kinds of climate and vineyard soils. It tends to be a late ripening grape which can lend itself well to the production of late harvest wines.
According to a 2000 census there were 1,734 hectares (4,285 acres) of Verduzzo Trevigiano growing in Italy, most of it within the Veneto provinces of Treviso and Venezia. Here the grape is a permitted variety in the Denominazione di origine controllata wines of the Lison-Pramaggiore DOC and Piave DOC, often blended with Verduzzo Friulano in wines that are varietally labelled as just Verduzzo. It is also used in some vino da tavolas in the region where some Venetian wine producers are experimenting with blending the grape with Chardonnay as well as barrel-fermentation and oak aging.
Over the years Verduzzo Trevigiano has been known under a variety of synonyms, many of which overlap with Verduzzo Friulano, including: Verduz, Verduza, Verduzo, Verduzz, Verduzzo, Verduzzo di Motta and Verduzzo Verde.
