WineFrog explains Douro
The Douro wine region located in the Douro River valley with the Montemuro and Marão mountains maintains a Mediterranean climate with dry, hot summers and cold winters.
It is broken down into three subregions from east to west:
Baixo Corgo has a moderate climate with the most precipitation. It was the first region to be planted and is considered the region with the least quality wines.
Cima Corgo is the largest of the three subregions, with 47,000 acres. It is where the majority of the wine estates, called Quintas, are located.
Douro Superior or Upper Douro
Douro Superior is the driest and hottest part of the Douro that extends as far as the Spanish border. It is known for producing the highest of quality wines of all the subregions and is the most recently planted, covering 21,000 acres and growing.
The wine styles which are made in the Douro Valley range from light-bodied, Bordeaux-style wines to rich, robust and sometimes rustic styles of Burgundian wine aged in new barrels.
