Valle d'Aosta Valle d’Aosta (the Aosta Valley) is located in extreme northwestern Italy, bordering both Switzerland and France. Its capital and largest town is Aosta. As Italy’s smallest and least populous region, most of it too mountainous for agriculture, Valle d’Aosta not surprisingly has by far the smallest wine production of any Italian region—just 14,500 hl (160,000 cases) in 2015—although its wines can occasionally be found on export markets. Interestingly, its production is two-thirds red; the region’s primary grape varieties are Petit Rouge (20%), Nebbiolo (12%), Pinot Nero (8%), Prié Blanc (8%), and Fumin (7%). It has just one DOC (see map), with no DOCGs or IGPs. Because of its proximity to France, Valle d’Aosta—or Vallée d’Aoste—often uses French terms in place of Italian ones.
