Red wine? Sounds like something a pugnacious type may pick (6)
I believe the answer is:
beaune
'red wine?' is the definition.
(type of French red wine)
'sounds like something a pugnacious type may pick' is the wordplay.
'sounds like' shows a homophone (sound like).
'something a pugnacious type may pick' becomes 'bone' (as in having a bone to pick with someone).
'bone' is a homophone of 'BEAUNE'.
(Other definitions for beaune that I've seen before include "Red Burgundy wine" , "French wine centre" , "French wine region" .)
