Oltrepò Pavese is the southernmost tip of Lombardy and covers 1.089 km2 in the province of Pavia, bordering Piedmont, Emilia and Liguria. The area has a triangular shape (which resembles a bunch of grapes), with the base being the Po River and the apex located in the first spurs of the Ligurian-Emilian Apennines, enclosed between the provinces of Alessandria and Piacenza. The region comprises four main valleys that radiate from the narrow strip of flat land just beyond the Po River into a vast central hilly area.
Oltrepò Pavese is one of the Italian largest and historic wine regions, renowned for the diversity of the grapes grown and the uniqueness of its wines. Pinot Noir and Croatina are some of the most widespread varieties, but many other grapes, like Barbera or Riesling, also found excellent conditions for their growth on the Oltrepò Pavese hills. The region is crossed by the 45th parallel, the famous wine parallel, that runs through some of the most famous wine regions of the world like Piedmont, Bordeaux and Oregon.
