You can't technically call this a bourbon, but it's basically a bourbon with a twist - it's aged in used bourbon barrels instead of brand new ones. But the result is you have a lot of the same bourbon notes you're used to, the corn, the oak, the vanilla and peppery rye. But putting it in used barrels gives it this unique profile that you're not used to with a standard bourbon, and I love it for that reason. The pepperyness is smoothed out and the vanilla notes feel a little amplified. You get a little less of the dry oaky flavor, it's still there but less dry and biting. Sweeter than a standard bourbon, but not overpoweringly so. This stuff is great, I'll be coming back.
