Apple brandy (8)
I believe the answer is:
calvados
'apple brandy' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for calvados that I've seen before include "Brandy distilled from apple cider" , "drink" , "Type of apple brandy" , "area near Caen" , "Vocal ads (anag) - apple brandy" .)
