The Cava wine category is evolving from its origins as a Denominación de Origen (DO) to the inception of five sparkling wine designations that are in use today: Conca del Riu Anoia, Clàssic Penedès, Corpinnat, Cava de Paraje Calificado, and Espumoso de Calidad de Rioja. These designations seek to improve the overall quality and global image of Spanish sparkling wine by focusing more on terroir and establishing higher standards—for aging, for production, for winegrowing, and more—than the original Cava DO traditionally has.
