Wine vaults (6)

I believe the answer is:

graves

I believe this is a double definition.

'wine' is the first definition.
(wine from the Graves region in France)

'vaults?' is the second definition.
(vault is a kind of grave)

(Other definitions for graves that I've seen before include "Burial places - French wine" , "White wine - found in churchyard" , "Wine - English poet - tombs" , "Table wine" , "Red or white wine" .)

I've seen this clue in The Globe and Mail, The Guardian and The Telegraph.
