Warm fruit-flavoured drink (7)
I believe the answer is:
cordial
This clue is a double definition.
'warm' is the first definition.
(similar in meaning)
'fruit-flavoured drink' is the second definition.
(Other definitions for cordial that I've seen before include "Agreeable - drink" , "drink with a fruity flavour" , "stimulating drink" , "Hearty - drink" , "7 [HEARTY]" .)
