Italian wine: Greek character not in favour (7)
I believe the answer is:
chianti
'italian wine' is the definition.
(I've seen this before)
'greek character not in favour' is the wordplay.
'greek character' becomes 'chi' (letter from the Greek alphabet).
'not in favour' becomes 'anti' (I've seen this before).
'chi'+'anti'='CHIANTI'
(Other definitions for chianti that I've seen before include "Dry red Italian wine" , "I can hit (anag) - alcoholic drink" , "Italian wine variety" , "I can hit for popular Italian wine" , "Wine produced in Tuscany" .)
