North African brewing ale with grain (8)
I believe the answer is:
algerian
'north african' is the definition.
(I've seen this before)
'brewing ale with grain' is the wordplay.
'brewing' is an anagram indicator.
'with' means one lot of letters go next to another.
'ale' after 'grain' is 'grainale'.
'grainale' with letters rearranged gives 'ALGERIAN'.
(Other definitions for algerian that I've seen before include "Native of a North African country" , "Native of Oran" , "Foreign" .)
