The soils in Niederösterreich are very diverse. One find Mica-schist in the Bohemian massif in the Kamptal region, but also bedrock weathered soils, covered with a thin coating of humus. The heart of Heiligenstein, an almost ideal partner for top-class Rieslings is a weathered desert sandstone from the Permian. Grüner Veltliner thrives on the gravel soils of Manhartsberg or the partly massive loess deposits that characterise the southern borders of this wine region.
