Drink some clarets inappropriately (7)
I believe the answer is:
retsina
'drink' is the definition.
(retsina is a kind of drink)
'some clarets inappropriately' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'RETSINA' can be found hidden inside 'clarets inappropriately'.
(Other definitions for retsina that I've seen before include "Type of Greek wine" , "S European wine" , "Nastier (anag) - white (or rose) wine" , "Greek white wine flavoured with resin" , "Greek drink" .)
