Recalling some cognac, rice, not exactly (5)

I believe the answer is:
circa
'exactly' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'recalling some cognac rice' is the wordplay.
'recalling' says the letters should be written backwards.
'some' says the answer is hidden in the clue (some parts of the word are used).
'acric' is hidden in the letters of 'cognac rice'.
'acric' reversed gives 'CIRCA'.
'not' acts as a link.
Can you help me to learn more?
(Other definitions for circa that I've seen before include "Close to" , "(Especially of a date) approximately" , "About (a time)" , "Costa del Sol city" , "Around (Latin)" .)
