Picked up a bottle of batch 4 recently, after enjoying some other Beam limited releases this year. I knew it didn't get great reviews at release, but had heard that the later batches were better. So let's see. Nose - dried oak, peanuts, cinnamon, cherries, vanilla, and barrel spice. Pretty typical KC bourbon nose. Palate - A bit thin for 100 proof, with peanuts, oak caramel, vanilla and baking spices. Some vague fruit notes. Finish is more of the same, but does not stick around long enough to coat the palate. So it's a pretty good bourbon, and representative of the Knob Creek profile. It's just not worthy of Limited Edition status (or price). This actually reminds me quite a bit of the Knob Creek 12 yr that started shipping this year. Maybe the 2001 is a little drier/oakier (but not much). The problem with that is the 12yr is readily available for half the price. So in that regard, this 2001 is a miss for me.
