The soils of San Polino range in their texture from sandy-loam to clay-loam with a rich scheleton presence. Interspersed throughout the fields are large areas of galestro (shale) and red earth.
The soil is well drained and has a good water permeability and, at the same time, good water retention.
A satisfactory natural presence of the essential nutrients necessary for healthy vine growth means that only a minimal quantity of fertilizers are ever used. In many years they are not used at all.
The vineyards face south and slope downhill at a gradient of 22%.
