French wine (7)
I believe the answer is:
'french wine' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chablis that I've seen before include "Classic white wine from Burgundy" , "Town in north central France noted for white Burgundy wines" , "French dry white wine" , "French town noted for white Burgundy wines" , "Burgundy town and white wine" .)
