Drink was revolting (4)
I believe the answer is:
rose
I believe this is a double definition.
'drink' is the first definition.
(rose is a kind of drink)
'was revolting' is the second definition.
(to rise up is to revolt)
(Other definitions for rose that I've seen before include "was being promoted" , "Thorny plant with bright flowers" , "Garden flower" , "Pinkish wine" , "''That which we call a ..., by any other name would smell as sweet'' (Romeo and Juliet)" .)
