(2010 Vintage) The Louis SIPP parcels of land are situated in the geological fracture zone of Ribeauvillé. They constitute a territory which is highly geologically fragmented. They are above all areas with hard chalk, clay and marl from the Liassic and Triassic periods, sandstone clay, and calcareous, chalky conglomerates from the Oligocene period. The area is also characterised by silt-laden deposits, originally loessial, and by glacis and sandy alluvium in the valley and on the plain. The vines of PINOT BLANC are generally located in areas of heavy and deep soil (Straeng), or in the parts of the vineyard which are late-fruiting.
