Terrior of the thermen- & Vulkanland
Wines from the winegrowing region of Vulkanland Steiermark are known for their outstanding quality – and it all has to do with the history of the earth. The growing area is characterised by ancient rock layers millions of years old, which were produced by active volcanoes some eight to ten million years ago. Today, the vine roots penetrate deep into the earth, searching for nutrients, where they are enriched by the mineral composition of the soil. Many vines grow on the deposits left by the Paratethys Ocean and the long-dried seas and rivers of the Styrian Basin, as well as on quarternary terrace gravels.
Volcanic rock occurs in the Vulkanland as tuff and basalt. Tuff is the material spewed explosively out of volcanoes millions of years ago, which then fell to earth as pyroclasts of different sizes and ash rain, hardening over time into a usually porous rock. Basalt, on the other hand, is cooled magma i.e. liquid rock from the bowels of the earth, which cooled after it was discharged and solidified into a hard and compact form, forming a new layer of rock and soil.
