Crossword Genius

Sack producer Marie knew to be dissipated (9)

Ross

I believe the answer is:

winemaker

'sack producer' is the definition.
(sack is a type of wine)

'marie knew to be dissipated' is the wordplay.
'to be dissipated' is an anagram indicator.
'marie'+'knew'='marieknew'
'marieknew' with letters rearranged gives 'WINEMAKER'.
