Trebbiano is Italy’s most widely-planted vine and is present in central and southern Italy alone in nearly eighty D.O.C. appellations, both red and white. It is the main grape of the blend of so many famous Italian white wines; Soave, Frascati, Verdicchio, and Orvieto, to name just a few. Known as Ugni Blanc in France, it is grown throughout the Midi, but is mostly used is as a base wine for the distillation of Cognac and Armagnac, though it is now making a comeback as a table wine in Gascogne. Also grown in most warm- to hot-climate viticultural areas of the world.
