Save pounds ultimately, meeting accountant over wine (6)

I believe the answer is:

barsac

I'm a little stuck... Click here to teach me more about this clue!

'over wine' is the definition.
'barsac' can be an answer for 'wine' (thesaurus). I'm not certain of the 'over' bit.

'save pounds ultimately meeting accountant' is the wordplay.
'save' becomes 'bar' (I've seen this before).
'ultimately' indicates one should take the final letters.
'meeting' says to put letters next to each other.
'accountant' becomes 'ac'.
The final letter of 'pounds' is 's'.
'bar'+'s'+'ac'='BARSAC'

Can you help me to learn more?

(Other definitions for barsac that I've seen before include "some from France" , "French wine" , "18 [WINE]" , "Scarab (anag) - sweet white wine" , "Sweet Bordeaux wine" .)

I've seen this clue in The Times.
