Nature of soils

The vines are planted on 3 types of soil :

- The Kimméridgian (Terres Blanches), geologic era when the Sancerre upper hills were formed, represents the main part of the estate (12 hectares).

These hillsides have about 30% to 45% slopes and are south-west to south-east-facing. Clays, main consituents of the soil, are very sensitive erosion. The ground is very damp in winter but drains quickly in summer which causes significant hydric stresses to the wine.

The wines grown on these hillsides will need time to fully express themselves. Elegant and structured, both red and white wines can be successfully kept.





- The Oxonian (Caillotes), geologic era when smaller hills were formed, represents about 5,5 hectares. Full south-facing, these very stony soils have great draining proprieties and quiclky heat up in spring. Thanks to this phenomenon, the vine generously grows;  the Sauvignon grape particularly.

The wines produced on these soils become expressive as soon as the fermentation stops and quickly release their mineral nature.

- The Barremian (Terres Rouges), is not widespread in the Sancerre's area. On our exploitation, only 3,4 hectares located to the east of Crezancy are planted with pinot grape. These are steep slopes, exposed south – south-east, with a soil composed of red clay, sand and very hard sandstone. This structure makes it very drainy.

Thanks to its dark color, it stores heat well. Pinot ripen early and give structured wines.
