Stout US ensign redeployed (8)
I believe the answer is:
guinness
'stout' is the definition.
(Guinness is an example)
'us ensign redeployed' is the wordplay.
'redeployed' is an anagram indicator.
'us'+'ensign'='usensign'
'usensign' with letters rearranged gives 'GUINNESS'.
(Other definitions for guinness that I've seen before include "The black stuff" , "Irish stout" , "Dark drink said to be good for you" , "A bitter stout" .)
