Steiger covers the area along the Danube stretching from Rossatzbach to the town of Rossatz. Although situated so closely to the Danube, the location must be considered a slope toe in geological terms. Deep soils characterised by erosion material not only produce fine fruity wines but also rich Smaragds.
Facing the Danube, the gently sloping Steiger vineyard is a prime example for a footslope location. Colluvial deposits of paragneiss, several metres thick, ensure a balanced water supply even in hot and dry summers. Moreover, the humus-rich topsoil improves water absorption and the water storage capacity, and supplies the vines with all essential nutrients. The soil contains some carbonate, which is an indication for a moderate loess fraction in the parent material.
