We hear whisky's to go up (4)
I believe the answer is:
rise
'to go up' is the definition.
(rising is a kind of going up)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rise that I've seen before include "Pay increase" , "Soar" , "Rebel" , "hike" , "To swell (bread)" .)
