Definition - What does Cava mean?
Cava is a type of white or red sparkling wine produced in Spain. This type of wine is similar to champagne because of its traditional production method, "champenoise". However, the difference between cava wine and champagne is the type of grapes used. The most popular grapes used to make cava include macabeu, xarel-lo and parellada. Even though there is a difference between cava and champagne and the EU law does not permit champagne to be labeled as cava, it is still informally and casually called champán (Spanish for champagne) in the villages of Spain.
