Strong beer (5)
I believe the answer is:
stout
I believe this is a double definition.
'strong' is the first definition.
(thesaurus)
'beer' is the second definition.
(type of beer)
(Other definitions for stout that I've seen before include "Dark beer for the rather fat" , "Beer with malt" , "Rather fat; determined" , "Rather fat, stocky" , "Full-bodied" .)
