The vines are planted on a subsoil essentially composed of pebbleweaves(granitas) and metamorphic rocks. This does not prevent the soils of Coteaux du Lyonnais to be very diversified. Three major zones form the vineyard and are distinguished according to the different types of soil that compose them. In the north, in the Sain Bel area, soils are derived from the alteration of granite and metamorphic rocks. In the South, the Turdine Valley consists mainly of sandy soils. Finally, on the slopes of the Monts d’Or, the soils are deeper, clay-limestone and clay-siliceous.
