Valle d’Aosta (Aosta Valley), with its approximately 3,000 square kilometers, is a small region, even in terms of wine production. The valley, formed by the Dora Baltea river, stretches from west to east and is surrounded by some of Europe’s highest mountains, including Mont Blanc (4,950 meters). Here, the climate exhibits significant variations depending on altitude, with an elevation difference of over 4,000 meters between the Lower valley area and the highest peaks. The weather is intensely cold during the winter season, subject to frequent spring frosts, and very high temperatures during the summer.
The right orographic side of the Central Valley, known as Envers, faces north and is characterized by the presence of forests. The left orographic side, called Adret, faces south and is cultivated with vineyards and orchards. The vineyard soils are primarily composed of granite in the Morgex area. In Arnad-Montjovet and Donnas, the soil is very thin, often exposing the bedrock, and is predominantly sandy-clay.
The diversification among the various wine-growing areas of the Central Valley is significant, and these areas are generally most suitable for the cultivation of white grape varieties.
