This was an impulse purchase. I didn't know much about it, other than that I've generally had good experiences with other Jefferson's products in the past. So instead of a backstory, here are some stats: This bottle is from Batch 4, Bottle No. 03209. It's bottled at a Jefferson's standard 45.1% ABV and is, obviously, finished in rum casks for an unspecified length of time. Nose: Vanilla, toffee, caramel, brown sugar, and butterscotch. A bit of molasses and sugar cane imparted by the rum cask. Some cherry sweetness and cocoa. A bit of Some pumpkin spice, and very, very mild baking spice. Fairly standard bourbon nose with a slight rum twist. Palate: The molasses and sugar cane are out in full force here. The vanilla, toffee, brown sugar, caramel, and butterscotch notes are now accompanied by milk chocolate and hazelnut. Some graham cracker and toasted marshmallow. More of the pumpkin spice, and a bit of ginger and cinnamon toward the tail end. This is some tasty stuff. Finish: Finish is all spice. At first it's more ginger, then a rush of cinnamon, black pepper, clove, nutmeg, and clove. Vanilla sweetness throughout. It's medium-long, which is very respectable considering the relatively average ABV. This was quite a surprise. I purchased it on a whim, without much expectation, and I've got to say this is damn fine stuff. It's the first rum cask-finished bourbon/American whiskey I've tried, and I've got to say that it is a fine combination when properly executed. At $70, I'd say it was a worthwhile purchase. I wouldn't pay any more, but I feel that it performs well in comparison to others at this price point. The highlight is the palate, but it's really good stuff from start to finish. The classic bourbon profile collides with a nice dosage of rum cask influence, making for a damn fine product. Highly recommend for bourbon fans look to break the mold. It's also a fine way to introduce a friend to whiskey in general. Damn good stuff.
