DO (D.O. Cava)

DO, or Denominación de Origen, is a certification that guarantees a Spanish wine’s quality and authenticity, indicating it was produced in a specific region following strict standards. D.O. Cava refers to sparkling wines from the Penedès region in Spain, primarily made through the traditional method of second fermentation in the bottle. This ensures the wine develops its characteristic bubbles and complex flavors. The DO designation assures consumers that the Cava adheres to established traditions, quality controls, and regional regulations, preserving the wine’s authenticity and distinguishing it from other sparkling wines outside that authorized area.
