Every year, the wines from Alto Adige win prizes and are awarded very high scores in the guides. In proportion to the quantity produced, which unfortunately is very low, they are the most prize-winning wines in Italy. The territory coincides with the province of Bolzano, and there is a slight prevalence of whites over reds and a small, but interesting, production of traditional method spumantes. There is little space for grape cultivation in the Alpine territory of Alto Adige, yet the region has an ancient wine-producing tradition, with several findings bearing witness to this. The vineyards lie between the valley floor and the mountain slopes, at altitudes which in some cases may even reach 1000 metres. The vineyard soil varies from the more calcareous to those with a prevalence of clay and sand; in some cases, hard rock rich in minerals can be found, including granite and quartz, and one example of this is Valle Isarco; other locations have a layer of volcanic porphyry, including the valley basin of Bolzano and the Terlano area. Generally, the region enjoys a sunny climate; the strong differences in temperature determine the original, intense and precise aromas of Alto Adige wines.
