The areas that make up the DO Cava, (denominación de origen), comprises of a total of 159 municipalities, all located within ten provinces; Barcelona, Tarragona, Lleida, Girona, La Rioja, Álava, Zaragoza, Navarra, Valencia and Badajoz. Although the DO is quite large, 95 percent of all Cava is produced within Catalonia, mainly in Penedès to be precise. The center of Penedès and of Cava production has for a long time been the city of Sant Sadurní d’Anoia, located about 40 kilometres west of Barcelona.
The heart of the region of which Sant Sadurní d’Anoia is the center, is the Anoia valley that in the North is protected by the impressive mountain of Montserrat, a rock formation with both very special geological structure and appearance, and also with enormous spiritual relevance for many Christians. To the South, the border is formed by the Mediterranean Sea, while in the East it takes the form of “el puente del diablo de Martorell”, the devil bridge in Martorell, of which there is also told a famous legend. The bridge was built by the Romans and since 1931 it received the status of a national monument. The border in the west is marked by another Roman monument, the triumphal arch in Berá. The valley is also protected in the West and East by mountains, however, neither as high nor as majestically beautiful as the Montserrat. All these surrounding mountains ensure a stable climate in Penedès and protect the valley from the cold winds coming in from the North. This is very beneficial when it comes to grape culturing since the grapes do not tolerate winds that are too cold. So, although the quality of the harvest yields naturally varies from year to year, it is largely thanks to the surrounding mountains that they are so high and of such a consistent quality in Penedès.
In the Anoia valley and Penedés the focus on Cava production is massive, although still wines are also made of course. Here the grapes are grown, and here the bubbles are born that later supply Spain and the rest of the world with its sparkling gold.
