Drink of cold coffee judge left out (4)
I believe the answer is:
cava
'drink' is the definition.
(alcoholic drink)
'cold coffee judge left out' is the wordplay.
I cannot quite understand how this works, but
'cold' could be 'c' (eg on taps) and 'c' is present in the answer.
The remaining letters 'ava' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for cava that I've seen before include "Spanish "champagne"" , "Spanish bubbly" , "sparkling drink" , "Spanish fizz" , "Spanish sparking wine" .)
