Song about swallowing orange juice and wine (5)
I believe the answer is:
rioja
'wine' is the definition.
(Rioja is an example)
'song about swallowing orange juice' is the wordplay.
'song' becomes 'air' (I've seen this before**).
'about' says the letters should be written in reverse.
'swallowing' indicates putting letters inside.
'orange juice' becomes 'oj'.
'air' backwards is 'ria'.
'ria' placed around 'oj' is 'RIOJA'.
'and' acts as a link.
(Other definitions for rioja that I've seen before include "Spanish red wine" , "Dry red wine from Spain" , "Open space (ancient Greek)" , "it comes from grapevine" , "North Spanish wine" .)
