Drink with Irish actor? (6)
I believe the answer is:
mescal
'drink' is the definition.
(mescal is a kind of drink)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for mescal that I've seen before include "Intoxicant from agave" , "Colourless Mexican spirit made from plant sap" , "Drink distilled from agave" .)
