I've got a friend who loves to drink Irish Whiskey neat (his "daily pour" of choice is Powers Irish Whisky, a bit too bland for me). He greatly enjoys bourbon when mixed 3/4 bourbon to 1/4 coke, but claims he cannot drink it neat or on the rocks. I got him to try my favorite everyday bourbon, Elijah Craig, and that was a no-go... so was Maker's Mark, which I've always been told is a good "introductory" bourbon.

So - my friend DOES like whisky, but hasn't yet found a bourbon he can drink neat - am I doomed to years of arguing with him over which whiskey is better, or are there other bourbons I should be recommending to him?
