Maker's Mark is one of the few "decent" whiskeys I've had that I just cannot drink. It comes off harsh and just unappealing compared to most. I realize I'm probably in a very small minority on this one. Still, give my Irish whiskey or something like Knob Creek over MM any day!
I do like scotch and can see the appeal of adding more smoke flavor, but I guess my inclination would be to reach for a bottle of something smokier to begin with. Seems like they are really trying to capitalize on the novelty/gimmick here.
