President not supplied with right wine (5)
I believe the answer is:
macon
'wine' is the definition.
(I know that Macon is a type of wine)
'president not supplied with right' is the wordplay.
'president' becomes 'Macron' (French president Emmanuel Macron).
'not supplied with' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'macron' with 'r' removed is 'MACON'.
(Other definitions for macon that I've seen before include "French wine region" , "Burgundian wine" , "Variety of Burgundy" , "red" , "Drink" .)
