Kitty, after quantity of money, brought back wine (6)
I believe the answer is:
muscat
'wine' is the definition.
(muscat is a kind of wine)
'kitty after quantity of money brought back' is the wordplay.
'kitty' becomes 'cat'.
'after' is a charade indicator (letters next to each other).
'quantity of money' becomes 'sum' (I've seen this before).
'brought back' says the letters should be written backwards.
'sum' backwards is 'mus'.
'cat' put after 'mus' is 'MUSCAT'.
(Other definitions for muscat that I've seen before include "Sweet aromatic grape" , "Sweet fortified wine" , "Arabic port" , "Variety of grape - capital of Oman" , "wine producer" .)
