Belted out revolutionary song making wine drink (7)
I believe the answer is:
sangria
'wine drink' is the definition.
(drink containing wine)
'belted out revolutionary song' is the wordplay.
'belted out' becomes 'sang' (I've seen this in another clue).
'revolutionary' says the letters should be written in reverse (letters revolve around).
'song' becomes 'air' (air can mean a piece of music).
'air' written backwards gives 'ria'.
'sang'+'ria'='SANGRIA'
'making' acts as a link.
(Other definitions for sangria that I've seen before include "Spanish drink of red wine, sugar and fruit" , "Spanish wine/fruit drink" , "Spanish drink of red wine and spices" , "Spanish drink of red wine with soda water or lemonade" , "Spanish spiced wine" .)
