Irish moonshine (6)
I believe the answer is:
poteen
'irish moonshine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for poteen that I've seen before include "Illegal drink" , "Illegal alcohol made from potatoes and other mash" , "Illicit Irish hooch" , "Illicit whiskey (Irish)" , "Illicit Irish drink" .)
