Wine region producing drink in pouch? Au contraire (6)
I believe the answer is:
alsace
'wine region' is the definition.
(French wine region)
'drink in pouch? au contraire' is the wordplay.
I cannot quite see how this works, but
'pouch?' could be 'sac' ('sac' can be a synonym of 'pouch') and 'sac' is located in the answer.
'drink' could be 'ale' (ale is a kind of drink) and 'ale' is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'producing' is the link.
(Other definitions for alsace that I've seen before include "French region bordering Germany and Switzerland" , "Region of France famous for white wine" , "White wine region of northeast France" , "French ------ -Lorraine, was German 1872-1919" , "area of France" .)
