Trevisana nera
Trevisana nera is a red Italian wine grape variety that is grown in the Veneto region of northeast Italy. While ampelographers believe that the name Trevisana suggest that the grape originated in the province of Treviso, today the grape is almost exclusively found in the northern province of Belluno, particularly around the comune of Feltre, where the grape is a permitted variety in the Indicazione geografica tipica zone of Vigneti delle Dolomiti.
History
The history of Trevisana nera is relatively recent with the grape's first documented appearance in viticultural documents dating to mid-20th century. While the grape has almost exclusively been found in the province of Belluno, ampelographers believe that the name Trevisana suggest an origin in the more southern Venetian province of Treviso, though DNA profiling has so far not shown any relationship between Trevisana and any other grapes from Treviso.From 2003 to 2008, DNA analysis showed that the Gattera and Borgogna grapes from the commune of Castelcucco in the province of Treviso and the Refosco di Guarnieri grape from the Friuli-Venezia Giulia wine region were identical to Trevisana nera.
