The soil types fall into three groups:
The first is clay-limestone with its fine layer of clay on a plateau of limestone parent rock, giving good drainage and a regular water supply in summer. This soil type makes up the larger part of the vineyard and is conducive to the maturation of the red grape varieties.
Then we have a type of deep clay which is colder and richer and supplies more water to the vine stock. This is where we grow the white grape varieties.
Finally, a sandy loam soil which is warmer but, with good management to keep the soil well aerated and to regulate water balance, is ideal for the production of rosé and light, fruity red wines.
