Reportedly posted bouquet (5)
I believe the answer is:
scent
'bouquet' is the definition.
(the scent of a wine)
'reportedly posted' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'posted' becomes 'sent' ('send' can be a synonym of 'post').
'sent' is a homophone of 'SCENT'.
(Other definitions for scent that I've seen before include "Perfume for the tracker" , "Distinctive aroma" , "Bouquet" , "Pleasant odour" , "Number of clues" .)
