Greek character (averse to wine) (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'greek character averse to' is the wordplay.
'greek character' becomes 'chi' (letter from the Greek alphabet).
'averse to' becomes 'anti'.
'chi'+'anti'='CHIANTI'
(Other definitions for chianti that I've seen before include "Tuscan red wine" , "Italian wine variety" , "Italian wine - mountain range" , "European wine" , "Popular dry red wine of Tuscany" .)
