most exquisite (6)
I believe the answer is:
finest
'most exquisite' is the definition.
('fine' can be a synonym of 'exquisite')
This is all the clue.
(Other definitions for finest that I've seen before include "Most delicate or topmost" , "Of the highest quality" , "Of the highest grade" , "Superior in quality" , "Most splendid" .)
