Wines to be served with brawn (5)
I believe the answer is:
sinew
'brawn' is the definition.
('sinew' can be a synonym of 'brawn')
'wines to be served' is the wordplay.
'to be served' indicates anagramming the letters.
'wines' anagrammed gives 'SINEW'.
'with' acts as a link.
(Other definitions for sinew that I've seen before include "power source" , "Strength; tendon" , "Tough material" , "Inelastic tissue" , "Muscular strength" .)
