The most striking geological element west of the Traisen is coarse, calcareous-dolomitic gravel, which was brought here by the Traisen about 15 million years ago from the rising Limestone Alps and poured into the Parathetys Sea in a delta. Over millions of years, the coarse rubble has solidified with sand and individual layers of marl to form a calcareous cemented conglomerate, the so-called HOLLENBURG-KARLSTETTNER CONGLOMERATE.

The soil fabric makes it difficult for the roots of the vines to access underground water reserves. The nutrients that give the wine its flavour are drawn up from the most diverse layers, which creates the fine-textured and highly complex style for which Traisental wines are known – crystal-clear, almost “angular” aromas along an extremely delicate acidity line, which contributes to their elegance and longevity.
