Although this parcel of the Loibenberg vineyard covers a relatively large area, only a small portion of it is used for vine growing because of the extremely rough terrain.
The Rauheneck section in the east of the Loibenberg vineyard is composed of Gföhl gneiss. Due to its south-western orientation, the Rauheneck was exposed more to westerly winds during the glaciation. Compared to the lee locations on the eastern side, this resulted in the deposition of thinner loess layers, which also eroded much more rapidly. Especially in the upper terrace locations, from which the profile was taken, the soils are carbonate-free and the wines are more delicate and firm than from vineyards with higher loess influence.
