Alcoholic drink: drunk earns it! (7)
I believe the answer is:
retsina
'alcoholic drink' is the definition.
(Greek resinated wine)
'drunk earns it' is the wordplay.
'drunk' indicates anagramming the letters.
'earns'+'it'='earnsit'
'earnsit' is an anagram of 'RETSINA'.
(Other definitions for retsina that I've seen before include "Nastier (anag) - Greek wine" , "Greek drink" , "Oily-tasting Greek white wine" , "Flavoured Greek white wine - nastier brand" , "Greek white wine flavoured with resin" .)
