Although 1991 might be considered an unremarkable vintage, it actually has an outstanding potential for development. A cool and dry spring gave way to a period in late June and the whole of July that combined many hours of sunshine with adequate rainfall. That was followed by a very hot and dry late summer and, as of the end of September, a wet autumn, in which the challenge was to take advantage of the few dry days to harvest the grapes.

• The quartz porphyry bedrock is of volcanic origin.
• The light, sandy-loamy soils are the foundation for naturally limited yields.
• The soils have a 55-60% quartz content and a slightly acidic pH.
• The minerally and distinctive wines are highly prized for their outstanding longevity.

Soil samples taken from three different sites have revealed the presence of a subvolcanic body around Terlano, which differs in composition from the classic volcanic rock. 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. Exceptional soil conditions influence the terroir of Terlano, where the vines have developed a specific reaction to micro-stress and produce their own terroir-specific polyphenols, which give the Terlano wines their distinctive character. The result is particularly salty wines with great tension and depth. The special mix of crystals and minerals in the Terlano soils produces white wines whose unique longevity never fails to impress the world’s wine gurus.

The high peaks of the main Alpine chain protect South Tyrol from the Atlantic winds and cold northerlies, while the region benefits from the Mediterranean climate from the south. Terlano has a remarkable microclimate, with pronounced differences in temperature between day and night caused by the cool downslope winds from the mountains.
To the south, a number of mountain massifs like the Adamello also have a protective function. As a result, annual precipitation is only about one-third of the average for the southern Alpine foothills, and the number of hours of sunshine is higher. The climatic conditions are not unlike those to be found in wine-growing areas like the Swiss Canton Valais.
When the sun rises behind the mountains east of Terlano on one of the year’s 300 sunny days, it is already high in the sky as the wine-growing area has a westerly to southwesterly exposure. The lower atmospheric density permits more direct solar irradiation with less diffuse sunlight. That increases the difference between the slopes on the sunny and shady sides of the valley.
