The Valle d'Aosta DOC (or Vallée d'Aoste DOC, in French) is an Italian denominazione di origine controllata located in the Aosta Valley of northwest Italy. Surrounded by the Alps, the Valle d'Aosta is home to the highest elevated vineyards in all of Europe. The principal winemaking region of the Valle d'Aosta is found along the eastern banks of the Dora Baltea (fr., Doire baltée) river with the city of Aosta serving as the central winemaking location. The region is divided into three main vineyard areas; the upper valley, Valdigne, the central valley (locally Valle centrale in Italian, Vallée centrale in French) and the lower valley, (locally Bassa valle in Italian, Basse vallée in French). To the south is the winemaking region of Piedmont. The Valle d'Aosta is Italy's smallest winemaking region both in terms of size and production with only about 330,000 cases produced annually in the region and only 36,000 cases produced under the DOC label. Seventy five percent of the area's production is red wine made mostly from the Pinot noir, Gamay and Petit Rouge varieties. A white wine is made from the indigenous Prié blanc grape by the cooperative of Blanc de Morgex et de La Salle.
The area of the Aosta valley has continental climate and despite its location in the Alps region the weather is typically very hot and dry in the summer time which tends to put harvesttime in early September. The geography of the wine regions is marked by high, steep slopes leading to the river valley which makes the use of mechanical vineyard equipment nearly impossible. The vineyard soils are composed primarily of sand at the higher elevation with more alluvial sediments of clay and gravel further down into the valley.
