A stout carrier (6)
I believe the answer is:
porter
This clue is a double definition.
'a stout' is the first definition.
('porter' can be a synonym of 'stout')
'carrier' is the second definition.
(thesaurus)
(Other definitions for porter that I've seen before include "Luggage-carrier and dark drink" , "One should have no difficulty carrying" , "One carries luggage" , "Dark sweet ale" , "Bitter beer - luggage carrier" .)
