More sensible to include chapter referring to wine (8)
I believe the answer is:
sancerre
'wine' is the definition.
(I've seen this before)
'more sensible to include chapter referring to' is the wordplay.
'more sensible' becomes 'saner'.
'to include' indicates putting letters inside.
'chapter' becomes 'c'.
'referring to' becomes 're'.
'saner' placed around 'c' is 'sancer'.
'sancer'+'re'='SANCERRE'
(Other definitions for sancerre that I've seen before include "Type of French white wine" , "Light French white wine" .)
