EU character not in favour of another's wine (7)
I believe the answer is:
chianti
'another's wine' is the definition.
(I know that Chianti is an red)
'eu character not in favour of' is the wordplay.
'eu character' becomes 'chi' (letter of the Greek alphabet).
'not in favour of' becomes 'anti' (I've seen this before).
'chi'+'anti'='CHIANTI'
(Other definitions for chianti that I've seen before include "I can hit (anag) - alcoholic drink" , "Popular dry red wine of Tuscany" , "Wine produced in Tuscany" , "Tuscan red wine" , "Italian wine - mountain range" .)
