Flavoured Greek wine (7)
I believe the answer is:
retsina
'flavoured greek wine' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for retsina that I've seen before include "Type of Greek wine" , "Nastier (anag) - white (or rose) wine" , "Greek drink" , "S European wine" , "Greek resin-flavoured wine" .)
