The soil

The soil is made up by a sedimentary complex of loam and sandstone of alluvial origin, which was originated through sedimentation on the bottom of the Tetide Ocean during the Eocene period. At first it presents itself solid but then through time, the farming work and the friable character of the ground have transformed the surface into a layer which is greatly suited to growing vines: here the shortage of organic substance is well balanced by the abundance of mineral elements and the clay works as a water reservoir for dry periods.
