Crooned with character knocking back alcoholic drink (7)
I believe the answer is:
sangria
'alcoholic drink' is the definition.
'sangria' can be an answer for 'drink' (sangria is a kind of drink). I'm not sure about the 'alcoholic' bit.
'crooned with character knocking back' is the wordplay.
'crooned' becomes 'sang'.
'with' is a charade indicator (letters next to each other).
'character' becomes 'air' (I've seen this before).
'knocking back' is a reversal indicator.
'air' backwards is 'ria'.
'sang'+'ria'='SANGRIA'
Can you help me to learn more?
(Other definitions for sangria that I've seen before include "A party drink" , "Spanish sweetened wine drink" , "Spanish spiced wine" , "found in Spanish bars" , "Mixed drink" .)
