My Connemara wife says she’s never heard of grain poitín - only ever potato.
Also, I was asking about “po-cheen” and she didn’t know what I was on about. Then we clarified we were talking about “putt-seen” (Connemara Irish pronuciation).
She also told me that, growing up, the local news regularly said “a man was found dead on the beach this weekend. Poitín was believed to be involved.”
