Tapped brew (4)
I believe the answer is:
beer
'tapped brew' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for beer that I've seen before include "Drink using hops, malt, etc" , "Drink brewed with malt" , "eg Bitter" , "Hop-flavoured drink" , "Hopped drink" .)
