Wine Rob tipped over — "oops" heard (8)
I believe the answer is:
bordeaux
'wine' is the definition.
(Bordeaux is an example)
'rob tipped over oops heard' is the wordplay.
'tipped over' shows that the letters should be reversed in order.
'oops' becomes 'd'oh' (both might be said after a mistake).
'heard' shows a homophone (sound like).
'doh' sounds like 'deaux'.
'rob' backwards is 'bor'.
'bor'+'deaux'='BORDEAUX'
(Other definitions for bordeaux that I've seen before include "French river port - claret" , "Major French centre of the wine trade" , "City in SW France" , "French city" , "Claret, for instance" .)
