Practically all types of parent material (parent rocks) are found in the AOC Beaujolais. On average, the soils are deeper than those for the crus or Beaujolais-Villages.
Farther east, there are a few large outcrops of shale and volcanic rock.
In the southern part of the largest Beaujolais AOC, we find typical soils from marl or hard limestone from the secondary era (sandstone, white limestone, fossiliferous limestone, golden stone).
Soils composed of parent rocks produce attractive, fresh and crisp wines.
