Wine area ” Südoststeiermark ” municipality Grafendorf / Hartberg, local district Reibersdorf, 460 m NN. South side, on terraced terrain. Terraces presumably Roman – nearby a “Roman villa”.
Brownearth to Rendzina over shell limestone (“Muschelkalk”). Deposit from the Sarmat, a shallow tributary of the middle portion of the Parathetis (12.7 to 11.6 million years ago). The calcareous sediments consist primarily of foraminifera shells (foraminifera limestone) into the individual mussel and snail shells are stored in an increasingly brackish becoming flat sea. The numerous ooliths that occur in the vineyards suggest a former flat, warm and calm sea with a strong vegetation of aquatic plants. In the middle area oft the vineyard there is only a thin layer of sandy soil above the sand-lime brick. This therefore has low water storage capacity.
The vegetation of the slopes is herbaceous and colorful and corresponds to the vegetation of a semi-dry grassland, an ecologically valuable meadow type, which has become very rare in Central Europe. These slopes account for about 50% of the total area and are especially promoted by us to maintain the high diversity of plants and animals. In this way, the vineyards form an ecological island in the surrounding agricultural landscape. By means of a yearly mowing, a fertilisation is to be prevented and the crop is removed. The species-rich fauna shows numerous warming species of butterflies, beetles, hymenoptera, grasshoppers, dipteras, snails, spiders etc. and a strong population of the Sandy Lizard. The biodiversity of the vineyard is documented in photographs and is constantly being expanded by new documents. It is available to interested parties in the photo gallery.
