Jack Daniel's Single Barrel Select

This is a four, maybe five-star whiskey . . . or would be, if it weren't for the finish, which is maybe one of the worst I've ever encountered in a whiskey. Nose and taste are trademark Jack, but more intense and--dare I say--beautiful: banana, caramel, vanilla, milk chocolate, berries, a touch of citrus and some varnish (though not unpleasantly so). But the aftertaste, the way it sits in your throat, is just brutal soggy wood, sour fruit, bitter corn, sour oak. Tremendously unpleasant. I've sampled from a few different barrels (as well as from the duty free-exclusive Silver Select), but they all seem to share the shockingly unpalatable finish.
