Setzberg

"The Setzberg must be divided into a large eastern half and a smaller western half. The probably most valuable dry grassland of the Wachau region lies between the two halves, which is also a designated natural monument.
In geological terms, the mountain unites several types of metamorphic rock: paragneiss, Spitzer granodiorite gneiss, marble, silicate marble, calc-silicate gneiss and scattered patches of loess on the east slope. In terms of the surface area, the variable paragneiss plays the most important role. It is therefore no surprise that the paragneisses occur in different forms on the Spitz and Laaben sides.
The location also represents a climatic divide separating the vineyards of Spitz from those of the Spitzer Graben. The wines produced on the two sides of the mountain differ accordingly."
