Alcoholic drink is a hit (5)
I believe the answer is:
punch
I believe this is a double definition.
'alcoholic drink' is the first definition.
'a hit' is the second definition.
(I've seen this before)
'is' is the link.
(Other definitions for punch that I've seen before include "horse to get > drink" , "Vigorous blow" , "Blow with the fist" , "Alcoholic fruit drink" , "Thump" .)
