The majority of the vineyards stand on loose, mostly silty, but also sandy or gravelly, young lake and river deposits of the Styrian Basin, which merges into the Pannonian Basin to the east. Not only are they very variable in grain size, but also in the carbonate content of limestone and dolomite components. In the northern and central part of the wine-growing region, the vines are rooted on different solid rocks from the Mesozoic and Prehistoric eras. These include lime phyllites, green slates and serpentinites from the geological unit of the Alps called Penninic. Rocks similar to those in the Rechnitz area and on the Eisenberg also form Austria's highest peak, the Grossglockner.

Especially in Deutsch Schützen and Eisenberg, heavy, iron-rich clay mixes with the mineral rock. Depending on the location, this combination creates exciting flavor variations and represents the uniqueness of our region.
