Bouquet inamorata holds back (5)
I believe the answer is:
aroma
'bouquet' is the definition.
(bouquet can mean a wine's aroma)
'inamorata holds back' is the wordplay.
'holds' indicates a hidden word.
'back' is a reversal indicator.
'amora' is hidden in the letters of 'inamorata'.
'amora' written backwards gives 'AROMA'.
(Other definitions for aroma that I've seen before include "Pervasive quality" , "A pleasant smell as of food" , "Perfume" , "particular charm" , "Savour" .)
