Sense of taste (6)
I believe the answer is:
palate
'sense of taste' is the definition.
(palate can mean someone's ability to taste)
This is all the clue.
(Other definitions for palate that I've seen before include "Sense of taste at roof of mouth" , "part of trap" , "A plate (anag.)" , "having ability to appreciate good food" , "relish" .)
