Production area for red wines, rosé wines, white wines and sparkling wines in the Italian region of Lombardy The zone (DOC, DOCG and IGT Provincia di Pavia) is the third largest in Italy after Asti and Chianti with 16,000 hectares of vineyards. The Oltrepò geographical area is located in the south of the province of Pavia, on the border with Piedmont and Emilia-Romagna. The total area is almost 100,000 hectares of mostly hilly and mountainous character at an altitude of 300 to 400 metres above sea level. The climate is characterized by particularly dry winters and ventilated summers, with high temperature variations due to air currents rising on the slopes. The soils of the foothills are made up of marine sedimentary rocks with an important clayey component.
The area covers 16,000 hectares in 42 municipalities in the Apennine foothills on the southern bank of the Po. About 12,000 are classified as DOC/DOCG area. However, about two thirds of the production is not produced as DOC/DOCG wine. Large quantities of grapes are delivered to large spumante wineries such as Cinzano, Gancia and Martini & Rossi in Piedmont or as cask wine to Milan to produce mass wines.
