The grapes for our S-Wines are grown on the pure, weathered volcanic and basalt soils of the Kaiserstuhl. These rocky subsoils are veined with grandiose calcareous seams which lend unique minerality and structure to these wines. This particular soil structure is unique in Europe. Strictly limited yields achieved by bunch-halving, vuneyard selection and careful vinification ensure that only the most expressive fruit from volcanic Kaiserstuhl soils is harvested year after year in order to then mature elegantly in small wooden barrels.
