Current drink (7)
I believe the answer is:
draught
I believe this clue is a double definition.
'current' is the first definition.
(a draught is a current of air)
'drink' is the second definition.
(I know that draught is a type of drink)
(Other definitions for draught that I've seen before include "drink needed" , "Unwelcome blow" , "man that may be crowned" , "Unwanted air current" , "it's felt, when short of cash" .)
