The South-Styrian Soil

The soils of southern Styria are very diverse, multi-layered, and dominated by sand, slate, marl and limestone. Most of the South-Styrian vineyards are planted on coarse aggregate. This was originally deposited by rivers, and has been consolidated here and there into conglomerates such as marl or argillaceous silt and sands, creating the "Styrian Marl" of the East-Styrian basin.

Conglomerates, aggregates, sands, and marl make up the "Weissenegg Formation". This stems from the sediments of the Styrian Basin originally deposited in the Paratethys Sea , and is between approx. eighteen and fifteen million years old. It is quite variable in grain size and lime content, often pure limestone. The Weissenegg Formation occurs locally between Wildon and Graßnitzberg, where the Polz brothers' vineyards are located.



( The Paratethys sea was a large shallow inland sea that stretched from the region north of the Alps over Central Europe to the Aral Sea in Central Asia. From the Pliocene epoch onward (after 5 million years ago), the Paratethys became progressively shallower. Today's Black Sea, Caspian Sea, Aral Sea, Lake Urmia, Namak Lake and others are remnants of the Paratethys Sea. Source: Wikipedia, Accessed in September 2020)
