Like the bad wine Ivan Grey made (8)
I believe the answer is:
vinegary
'like the bad wine' is the definition.
'ivan grey made' is the wordplay.
'made' indicates anagramming the letters.
'ivan'+'grey'='ivangrey'
'ivangrey' anagrammed gives 'VINEGARY'.
(Other definitions for vinegary that I've seen before include "Acerbic" , "Peevish" , "bitter" , "Sour tasting" .)
