Abruzzo, mountainous region in central Italy with a significant coastline on the Adriatic sea to the south of marche and an important producer of wine (see map under italy). Abruzzo is seventh among Italy’s regions in terms of production, with a total output of just over 2 million hl (nearly 53 million gal) in 2011. Despite the presence of one of Italy’s better red grape varieties montepulciano d’Abruzzo, the warm climate, and favourable vineyard sites where the hills descend towards the Adriatic and enjoy the benefits of summer heat and solar radiation from the sea, most of the region’s production is still undistinguished.
