Differentiating and grouping of oltrepo’ pavese environments according to grape maturation

The maturation patterns process has been very studied. In particular the modelization of the sugars and titratable acidity during the ripening period was an important approach, in particular for the prediction of harvest date (Barillere et al., 1988; Jourion et al.,1987; Maujean et al., 1983; Scienza, 1989). In Oltrepò Pavese, the widest viticultural district of Lombardy – Northern Italy – (about 15000 hectares), grape maturation trends shows high variability, due to the large variation in environmental characteristics of vineyards (altitude, exposure, soil type, mesoclimate) and to “cultivar x environment” interaction.
In 1994 C.I.VI.FRU.CE. the agricultural experimental station of Lombardy Regional Government, started a programme to study the different type of grape maturation in Oltrepò Pavese.
