Wine gum unwrapped? (4)
I believe the answer is:
asti
'wine' is the definition.
(Italian wine)
'gum unwrapped?' is the wordplay.
'gum' becomes 'mastic' (mastic is a resin also called arabian gum).
'unwrapped?' indicates the central letters (the letters which wrap the word are removed).
The middle of 'mastic' is 'ASTI'.
(Other definitions for asti that I've seen before include "Italian white wine" , "Sparkling drink" , "Italian product" , "Sparkling white wine" , "- spumante, It. wine" .)
