Region for French wine: borders of Champagne (8)
I believe the answer is:
province
'region' is the definition.
(province is a kind of region)
'for french wine borders of champagne' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'french wine' becomes 'vin' ('wine' in French).
'borders of' suggests removing the centre.
'champagne' with its middle taken out is 'ce'.
'pro'+'vin'+'ce'='PROVINCE'
(Other definitions for province that I've seen before include "Administrative region" , "Ulster or Munster, say" , "Area of activity" , "Territory" , "Administrative division of a country" .)
