Some kind of wonderful! I finally had my last pour out of this bottle last night and it was bittersweet. So great to enjoy but so sad it was the last pour. The nose is really good, the palate is great, and the finish dances around as long as you could hope for. Though the proof doesn't satisfy the chest thumpers, I think the absence of the typical GTS heat allows so many more subtle flavors of 15 years of age to come through. I've had alot of great bourbons, but this one fits my tastes perfectly and I don't think I'll ever forget it.
