Fermented Argentine fruit (9)
I believe the answer is:
tangerine
'fruit' is the definition.
(tangerine is a kind of fruit)
'fermented argentine' is the wordplay.
'fermented' is an anagram indicator.
'argentine' anagrammed gives 'TANGERINE'.
(Other definitions for tangerine that I've seen before include "fruit product" , "Small citrus fruit with a loose skin" , "Tree" , "Small orange-like fruit (from North Africa?)" , "Moroccan" .)
