In France the art remains shunned by consumers (4)
I believe the answer is:
lees
'remains shunned by consumers' is the definition.
(dregs of wine which you don't drink)
'in france the art' is the wordplay.
'in france the' becomes 'le' ('the' in French).
'art' becomes 'es' (I can't explain this - if you can you should give a lot more credence to this answer).
'le'+'es'='LEES'
Can you help me to learn more?
(Other definitions for lees that I've seen before include "Sediement or else" , "Wine dregs" , "Dregs, sediment" , "Deposit" , "Grounds" .)
