Once again the traditional Kalterer wine days will take place! >
As far as soil is concerned, the terroir of the South Tyrolean vineyards is like a complex puzzle. The geological structure varies greatly from vineyard to vineyard. On the hillside locations, these vineyards thrive on the gravel soils that have formed over the centuries due to glacial erosion.
All around Kaltern, the soils contain large amounts of igneous rock: crimson-colored porphyry mixed with clay or sand. In this dry soil, which is lacking in humus, the vines must build deep root structures in order to reach and obtain sufficient water sources. In the southern-most vineyard section of South Tyrol, the soil is made up of disintegrated limestone and weathered Dolomite rock.
