The quest to enjoy barrel proof products continues as another worthy contender steps up: Nose: lite sweet caramel and toffee, sweet pineapple and hints of mango with rich butterscotch, entirely appealing, if slightly unusual. Front: A load of butterscotch lemon, rich toffee and tobacco bitters help balance the sweetness and some of that legendary barton barn door oak peeks through near the end. At the top some caramels, brown sugar starches and fruit notes can be detected along with some black peppery heat and clove and kitchen spices. Finish: a bit rough as the richness tapers into some nutty wood after taste, nothing too harsh or unpleasant, just nothing like the smooth sweet start to this proofy liquid and the hearty middle bite it offers. Considerably less heat at the end than might be expected. Having a chance pickup of the 1792 Single Barrel on the cheap and given it is a single barrel and Bartons upper level product, I couldn't pass this one up and now I'm glad I didn't. Bottled at 98.x proof there is a good bit of flavor packed into this Bardstown offering and while some of the 1792 bottles are less than remarkable, the barrel strength is enjoyable if not quite on the high level as some of the BT and SunBeam barrel proof products. Worth picking up below 50-55ish or as a bar whistle wetter. Broke out an Archetype Axis Mundi for this sampling, the Axis is an amazingly smooth stick.
