The Middle Adige Valley, where Cantina Terlano is located, was formed during the last Ice Age. The Adige glacier, probably over 1000 m thick, carved a wide U-shaped valley with steep sides. As the glacier melted, the steep slopes became free of ice and exposed to erosion. What is now the valley floor was covered with deposits of gravel, boulder clay, sediments and mudflows.
The skeletal sandy loamy soils have a high quartz content. The absence of calcium carbonate explains the slightly acid pH values. These factors result in a high permeability to water, a limited nutrient supply and thus balanced growth with naturally limited yields.
