Illicit Irish hooch (6)
I believe the answer is:
poteen
'illicit irish hooch' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for poteen that I've seen before include "Unlawfully distilled Irish whiskey" , "Illegal Irish spirit made in still" , "Home made spirit" , "Illicit Irish drink" , "illicit booze" .)
