Heavenly drink (6)
I believe the answer is:
nectar
'heavenly drink' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nectar that I've seen before include "Ambrosia" , "Sweet liquid of the gods" , "Source of honey" , "Heavenly drink, may create trance" , "Sugary plant fluid" .)
