Chapter one not in favour of wine (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'chapter one not in favour of' is the wordplay.
'chapter' becomes 'ch'.
'one' becomes 'i' (Roman numeral).
'not in favour of' becomes 'anti' (I've seen this before).
'ch'+'i'+'anti'='CHIANTI'
(Other definitions for chianti that I've seen before include "Popular dry red wine of Tuscany" , "Dry red Italian wine" , "I can hit (anag) - alcoholic drink" , "Italian wine - mountain range" , "Chain it to popular Italian wine" .)
