Color is burnished copper, maybe not quite as dark as I'd expect for the age (but then again it's 'only' 100 proof). Nose - Dark and earthy with leather, oak, vanilla, tobacco, clove, cinnamon;  some caramel lurking underneath, but it's not a particularly sweet nose. Definitely has that WT funk note. After breathing for a bit, I get some dark cherry and red apple. Palate -  medium mouthfeel, slightly oily. Starts with burnt caramel, vanilla, black tea, leather, and oak; also some clove, a bit of cinnamon. There's a smoky note in there as well. Not really getting much fruit on the palate, maybe some baked/spiced apples.  Medium finish is fairly dry, with notes of oak, cocoa powder, and pepper lingering. I've enjoyed all of the Master's Keep releases, and this one is no exception. It's been a while since I've had Decades, but I remember it being a bit richer/sweeter while this one is drier and more complex. There's a dried leather note in this BiB that reminds me of RR2002. I'm deducting a quarter point based on the price (which I feel is reasonable in the current market but certainly not a 'value'), and for the fact that I think that the proof is holding it back from it's true potential.
