Cava is a Spanish sparkling wine made using the traditional method, similar to that of Champagne, involving secondary fermentation in the bottle. Produced mainly in the Penedès region in Catalonia, Cava can be made from a variety of grapes, including Macabeo, Parellada, and Xarel·lo. It ranges in style from dry (brut) to sweet, offering a more affordable alternative to Champagne with its own distinct characteristics.
