Italian brandy (6)
I believe the answer is:
grappa
'italian brandy' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for grappa that I've seen before include "Spirit distilled from grapes" , "Spirit distilled from fermented grape remains" , "Type of brandy" , "Italian firewater" , "Brandy made from wine press residue" .)
