Stock of wines (6)
I believe the answer is:
cellar
'stock of wines' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cellar that I've seen before include "Bottom room where wine may be stored" , "Room below ground for storage" , "Storage space below ground" , "Storage space, for wine perhaps" , "Space for storing wine, say" .)
