If you approach near to the stones and swipe your finger over them you can see and feel the typical composition of the stones. Dr. Andreas Lehmann, expert for soil science, will explain that geology is an important basis for the character of this steep vineyard. „Dominant for this hillside is a grit sandstone called „Stubensandstein“ with single grain to be seen here. It got its name not from the rock you can see, but there is also a softer kind of it. It was mined in the Welzheimer Forest and used to clean the floor in the living rooms (in German „die Stube“).
From the single stones please enjoy the view over the valley:
„Having a look at the floodplains of the Neckarvalley near Esslingen you can see the fertile soil used for agriculture which was the basis for settlement in Esslingen. Sediments are from the young Quaternary era. When your eyes go upwards you will find the rock face in the middle – a rather old geological formation, the Keuper layer, which is about 200 million years old. Only one layer inbetween is the so-called „Stubensandstein“ (sandstone) which you can find here at the rocks and which is basis material for the walls in the vineyards.“
There is the question why the slope is so steep?
„The key player is the river Neckar that due to water erosion grabbed a way through the Keuper layer. It is steep because of the hard sandstone.“ With the hard sandstone the steep slope was reclaimed, but the enormous pressure of the hillside still remains. The dry walls although they are in high quality, well thought-out built can not bear the pressure forever more. Today we can see many places where the walls are destroyed due to the high pressure of the hillside. It is a big job to rebuild the walls for a long life. In fact, there is nothing better than this old traditional dry wall building – attractive and long lasting.
