Climate conditions are of primary importance for the grapes ripening degree. Most of the hilly territory around Bertinoro is formed by a calcareous- marly and arenaceous compound, according to the rock of origin, and by a medium compact structure, loose or even pebbly, usually very rich in skeleton and often rather deep and fresh.

The resulting profile is very undulating: this makes drainage easier allowing the vine good agronomic conditions. Remnants of shells and other organic residues, which bound together, nowadays form a large limestone barrier, the so-called "Spungone Romagnolo". The limestone presence gives the wines, particularly the white ones, marked scents, elegance and softness, richness and structure
