So a blend of 11, 15, and 21 year old bourbon bottled at 56.37%. I'm sure there are some mixes of their different types but frankly I don't know a lot about four roses and I generally don't care for their bourbon. Nose - sweet vanilla, pine, some cinnamon, some kinds of pie crust and marmalade, leather, oak, shoe vanish. You really get that there's an old whisky in here. An almost dusty antique oak note. Water brings out vanilla and spice and pushes the dusty oak back just a bit, no real change in the notes I get, just how they come across. Taste - Cinnamon apple pie, oak, spices, vanilla. There are 3 or 4 transitions from sweet up front to a light spicy and lightly hot finish, but then it has a second finish where the spices come even stronger, and then a 4th just lingering spicy oak note. Water much like the nose brings a bit more sweetness out but doesn't change the transitions and spices over leathered oak and all the cinnamon apple pie like notes. Overall, this whisky has changed my mind on Four Roses. The complexity here is completely off the charts. it brings all the characteristics of good old well aged bourbon, the leather, that deep vanilla, that high quality oak note, and then it brings with it the punch and the fire of younger whisky (not so young as to be rot gut of course). I'm absolutely impressed with four roses here, now if they can just make more of the older stuff and less of their regular line up. I'm going 4.25 here. An outstanding bourbon, but lets not go crazy yet here.
