Enduring brew (5)
I believe the answer is:
stout
I believe this clue is a double definition.
'enduring' is the first definition.
(thesaurus)
'brew' is the second definition.
(I know that stout is a type of ale)
(Other definitions for stout that I've seen before include "Portly - type of dark beer" , "Resolute" , "Fat; dependable" , "pint" , "Heavily built; drink" .)
