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.
