Yes, the Irish do make the best whiskey (I'm thinking Tully's here), but do remember that those who originally settled Kentucky and Tennessee were "Old Irish" (those who settled in the States before the Revolutionary War, as opposed to the "New Irish" who immigrated during and after the Great Potato Famine).
Pinged Gael because of the Irish content, in case he's wondering.
I realize that. What amazes me is that nothing they made America could compare to any whiskey made in Ireland. It's got to different soil the ingredients are grown in.
