About 95% of all cava is produced in the Penedès area in Catalonia, Spain, with the village of Sant Sadurní d'Anoia being home to many of the largest Catalan production houses.
Cava is also produced in other villages in the provinces of Girona, Lleida, Tarragona, and Barcelona in Catalonia, Zaragoza in Aragon, Badajoz in Extremadura, La Rioja, Araba/Álava in the Basque Country, Navarra and València in the Valencian Community.
[1] Today it is defined by law as a "quality sparkling wine produced in a designated region" (Vino Espumoso de Calidad Producido en una Región Determinada, VECPRD).

Catalan cava producers pioneered a significant technological development in sparkling wine production with the invention of the gyropallet, a large mechanized device that replaced hand riddling, in which the lees are consolidated in the neck of the bottle prior to disgorgement and corking.
Cava is also produced in other villages in Aragon, Castile and León, Extremadura, la Rioja, Basque Country, Navarre and Valencia.
