Wine that's fine in Champagne region? (4)
I believe the answer is:
cava
'wine' is the definition.
(type of Spanish wine)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for cava that I've seen before include "Spanish sparkling white wine" , "Spanish "champagne"" , "sparkling drink" , "Sparkler" , "Spanish bubbly" .)
