Verduzzo Trevigiano is a white Venetian grape variety that is grown in the Eastern Veneto wine area (northeast of Italy). In the past the name Verduz referred to a wide range of grape varieties in the Venetian area. By the descriptions found, they were often morphologically very different, but shared the character of late ripening. However we can very frequently find the name Verduzzo in the ampelographic list of the 19th century, there is not any sign of this Verduzzo until the beginning of the 20th century. At that time just two varieties, with the same name Verduzzo, were still cultivated in the Veneto and Friuli area, they were what we today call Verduzzo Friulano and Verduzzo Trevigiano. The two varieties are clearly different, as demonstrated even with DNA profiling analyses in 2010 and 2011.[1] However at the beginning of the 20th century, the two Verduzzo were called with the same name and often were present in the same vineyard and made wine together. Cosmo proposed to call the two varieties with different names: Verduzzo friulano for the varieties typical of Ramandolo production that was the only one present in that area of Friuli, and Verduzzo Trevigiano for the other one, that was present in the oriental zone of Veneto, where even Verduzzo friulano was spread, but which has a sure origin in the Treviso province how showed by the papers of Lepido Rocco.
