The Mazzolino Tenuta lies in the heart of the Oltrepò Pavese controlled designation of origin area, on the right bank of the Po River, in the hilly area close to the Apennines, along the 45th parallel.
Lying on clay soils with steep slopes typical of Oltrepò Pavese, the Tenuta's crus rest deep on sometimes sandy, sometimes sandy substrates. A common denominator is the strong presence of limestone-chalk veins in which the roots sink in search of water and precious mineral microelements.
The extreme variety of exposures and soil characteristics suggested the subdivision into 39 small plots managed separately. The goal of agronomic management is simply to enhance each of their individual expressions. No fertilizers are used, but the ancient technique of green manure, according to which field beans, alfalfa and phacelia are sown between the rows, enriching the soil and protecting it from erosion and crushing; nothing but copper and sulfur are used for treatments.
