The Peneès wine-making region of Catalonia in Northeast Spain lies to the south-west of the city of Barcelona. The area is framed by the coastal hills of the Garraf and the higher inland mountains which skirt the Central Depression. Long considered one of the country's best wine-producing regions after the Rioja, it is also one of the most ancient viticultural areas in Europe. Perhaps better-known for its Cava production (a sparkling wine which has had its own Denominació d'Origen since 1991) white grape varieties predominate, although the region also produces some highly-regarded, oak-aged reds.
