Trentino-Alto Adige is located just below Austria in the valleys surrounded in the rugged mountains of the Alps and the accompanying steep hills, blanketed in rich vegetation, including rows and rows of vineyards growing native and international grapes. The climate varies greatly, ranging from strictly alpine to one that is milder, with Dolomitic calcareous soils abounding in some areas and alluvial soils with gravel and stones in others. Over half of the crops grown in the area are dedicated to wine, reaching almost 10,000 hectares (24,700 acres) under vine. The grapes most grown here are without a doubt Chardonnay and Pinot Grigio followed by others, such as Muller Thurgau, Traminer Aromatico, Pinot Bianco, Sauvignon, Nosiola, Riesling and many others. Reds, such as Pinot Noir, Cabernet Sauvignon and Franc, as well as Teroldego and Merlot do very well here.
