Infused drink (3)
I believe the answer is:
tea
'infused drink' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tea that I've seen before include "The cup that cheers but not inebriates" , "going to pot?" , "Dried leaf infusion" , "A light meal - eat up" , "Afternoon meal; drink" .)
