Sample of fakir's cherry brandy (6)
I believe the answer is:
kirsch
'brandy' is the definition.
(kirsch is a kind of brandy)
'sample of fakir's cherry' is the wordplay.
'sample of' says the answer is hidden in the clue (I've seen this in other clues).
'KIRSCH' is hidden in the letters of 'fakirs cherry'.
(Other definitions for kirsch that I've seen before include "Liqueur distilled from black cherries" , "German cherry brandy" , "Brandy distilled from cherries" , "Liqueur made from cherries" , "Wild cherry liqueur" .)
