I'm a little stuck... Click here to teach me more about this clue!

'sparkling wine' is the definition.
(Spanish sparkling wine)

I cannot understand how the remainder of the clue works.

(Other definitions for cava that I've seen before include "sparkling drink" , "Spanish bubbly" , "Spanish sparking wine" , "Sparkler" , "Spanish "champagne"" .)

I've seen this clue in The Independent.
