Beer is brought into passageway (5)
I believe the answer is:
aisle
'passageway' is the definition.
(aisle is a kind of passageway)
'beer is brought into' is the wordplay.
'beer' becomes 'ale' (type of beer).
'brought into' indicates putting letters inside.
'ale' enclosing 'is' is 'AISLE'.
(Other definitions for aisle that I've seen before include "Way between seats" , "Way between seat blocks" , "Passage between shelves in supermarket" , "Way between seating areas" , "Passage between blocks of chairs" .)
