Connoisseurs (9)
I believe the answer is:
aesthetes
'connoisseurs' is the definition.
(aesthete is a kind of connoisseur)
This is the entire clue.
(Other definitions for aesthetes that I've seen before include "lovers of Grace?" , "arty types" , "They have great sensitivity to the beauty of art and nature" , "They profess great sensitivity to art and beauty" .)
