The clay-limestone plateau of Saint-Emilion
|Located on a limestone molasse on the south borders of the plateau of Saint-Émilion, the vines of Chateau La Croizille are spread out in a sort of circus sculpted in the rock (the combe).
The molasse or sub-soil consists of soft rock mixed with clay. The soil has a clay texture and a high retention capacity. Indeed, the particularity of this soil consists in the fact that it stores the surplus of water accumulated during rainy periods to restitute it to the vines during drought periods. The calcium on the other hand gives it much structure and the topographic position of the parcels facilitates the drainage.
Apart from the clay and the limestone, we also find pure lime, blue and red clay and even loam.
