Partly secret sin — alcoholic drink (7)

I believe the answer is:

retsina

'drink' is the definition.
(retsina is a kind of drink)

'partly secret sin alcoholic' is the wordplay.
'partly' indicates a hidden word (part of the clue is used).
'RETSINA' is hidden within 'secret sin alcoholic'.

(Other definitions for retsina that I've seen before include "Nastier (anag) - white (or rose) wine" , "Greek wine - nastier sort" , "Nastier (anag) - Greek wine" , "S European wine" , "Flavoured Greek white wine - nastier brand" .)

I've seen this clue in The Times.
