The white grape Trebbiano Toscano is grown in the regions: Abruzzo, Basilicata, Calabria, Campania, Emilia-Romagna, Lazio, Liguria, Lombardy, Marche, Molise, Puglia, Sardinia, Sicily, Tuscany, Trentino Alto Adige, Umbria, and Veneto.
Trebbiano Toscano is a grape variety of probable Etruscan origin, certainly among the most important of the numerous "trebbiano" family. Already mentioned by Pliny the Elder, the name is supposed to be traced back to a place of the same name in ancient Etruria near Luni, on the border between Liguria and Tuscany, or to the Trebbia River in the Colli Piacentini.
