Character; taste (7)
I believe the answer is:
I believe this clue is a double definition.
'character' is the first definition.
(both can mean a quality or style)
'taste' is the second definition.
(flavour is a kind of taste)
(Other definitions for flavour that I've seen before include "Relish" , "property" , "Distinctive taste" , "Season" , "essential quality" .)
