While the variety, cellar philosophy and vineyard vegetation are all factors that significantly impact a finished wine's nose and taste, it is its 'natural foundation,' the soil itself, that makes perhaps the greatest impact.
Tectonic upheaval in the Rhine rift around Birkweiler, Albersweiler and Frankweiler led to very old and deep geological formations moving up to the surface.
· Rotliegendes (Permian)
· Colored Sandstone (Triassic)
· Shell Limestone (Triassic)
· Colored Marl (Triassic)
These soils can be found scattered in the slopes surrounding the village of Siebeldingen, in many cases with notable features of weathering.
The formation of the Rhine rift and Quiech River valley in more recent geological history produced our unique and layered soil make-up:
· Slope and terrace gravel (Quaternary)
· Loess and loess-loam (Ice Age)
Each geological composition imbues a unique sensory character to the wines growing in it.
