Grant, perhaps, to import a new sweet wine (6)
I believe the answer is:
canary
'sweet wine' is the definition.
(sweet fortified wine)
'grant perhaps to import a new' is the wordplay.
'grant perhaps' becomes 'Cary' (actor Cary Grant).
'to import' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'a'+'n'='an'
'cary' enclosing 'an' is 'CANARY'.
(Other definitions for canary that I've seen before include "Pet bird" , "Type of finch" , "Bright yellow songbird" , "grass" , "Yellow singing bird" .)
