The geological composition and its related effects vary from vine to vine and it is from this unique soil diversity
that the prerequisites for a precious biodiversity are born.

On the slopes predominate the gravelly limestone soils of Dolomite rocks, which also originated during the glaciations. They are characterised by a high pH value and good nutrient storage capacity. The presence of a high clay content, for example, favours the growth of Pinot Noir. The gravelly-sandy calcareous soils, on the other hand, are suitable for varieties such as Pinot Blanc and Sauvignon.

The moraine debris around Appiano originated from deposits from the glacial period. It has a low pH, is well aerated and permeable only to a certain depth. Slow ripening of the grapes is characteristic of this type of soil. In the winegrowing municipality of Appiano, on this type of soil, are grown white wines such as Chardonnay, Pinot Grigio and Gewurztraminer.

The porphyritic reddish-colored soils are composed of disrupted volcanic rocks mixed with clay and sand. These dry and humus-poor soils are excellent heat accumulators, permeable to light and generally well ventilated and are mainly suitable for the production of Sauvignon and Riesling.

The alluvial soils were formed in a similar way to the morainic ones - material transported by rivers and deposited on the banks, creating sandy soil with few stones. These Flins (as alluvial soils are called in Alto Adige), create an ideal terrain for Lagrein, Merlot and Cabernet wines.
