Aosta Valley (Valle d'Aosta) is Italy's smallest and least populous region, just one-eighth the size of neighbouring Piedmont. Located in the north west corner of Italy’s, bordering with France and Switzerland, is the Aosta Valley (Valle d’Aosta, in Italian),

Despite the region's small size and minimal fame, a wide range of both red and white wines are made here from a selection of both native and international grape varieties, the most important of which is Picotendro, the local variety of Nebbiolo, other native grapes are Cornalin, Fumin and Petit Rouge, amongst the introduced grapes there are Petite Arvine, Syrah, Gamay and Chardonnay. Aosta Valley, compared to the other 20 Italian regions, has the smallest wine production.

Most vineyards in the Aosta Valley occupy the steep, south-facing slopes above the Dora Baltea river, a tributary of the Po. The dramatic topography and diminutive size of the valley mean that the area available for viticulture is limited and much of the valley floor, with its mineral-rich, well-watered soils, is simply too fertile for quality viticulture. As a result, many of the best vineyards here are on the lower slopes, and climb steadily up the slopes to top altitudes of around 1300m above sea level.

Due to its topography, most of the vineyards in the Aosta Valley are cut into terraces for ease of accessibility during harvest.
