Bouquet from an Italian citizen? Not quite (5)
I believe the answer is:
aroma
'bouquet' is the definition.
(bouquet can mean a wine's aroma)
'an italian citizen? not quite' is the wordplay.
'an italian citizen?' becomes 'a roman' (an inhabitant of Rome).
'not quite' means to remove the last letter (most but not all of the word).
'aroman' with its final letter taken away is 'AROMA'.
'from' is the link.
(Other definitions for aroma that I've seen before include "Fragrance of spices" , "Spicy fragrance" , "Test of knowledge" , "Scent - smell" , "A pleasant smell as of food" .)
