Terroir: Itria Valley spreads over the provinces of Bari, Brindisi and Taranto, and coincides with the lower part of the Murgia (Le Murge) upland. “Valley” is an inaccurate term because Itria Valley has not the typical conformation of mountain area valleys: it is just a depression due to karstic phenomena. The towns of Martina Franca, Locorotondo, Cisternino and Ceglie Messapica overlook Itria Valley. The area is known for its trulli (ancient stone dwellings), and the production of wine and olive oil.
Winegrowing in the Valle d’Itria contrasts with the Puglian tendency towards red-wine grapes; its vineyards, for the most part tiny plots of land cared for piece by piece, have for centuries been devoted to white grapes, which display delicate aromas and good acidity levels. Two varieties have always predominated, Verdeca and Bianco d’Alessano; in various proportions, they make up the two principal local DOC wines, Martina Franca DOC and Locorotondo DOC. Ostuni DOC, produced in the same area, relies on lesser-known native white grapes, Impigno and Francavidda, while the production code for the area’s red wines specifies Ottavianello as the predominant variety.
