The nose of Old Forester 100 Proof Bourbon is, as you would expect, a little bit richer than the 86-proof Old Forester version. The nose is more oak forward intermingled with some light brown sugar. The aroma is almost a perfect blend of the two. After a sip, you can smell the ethanol.
The palate centers around a little bit of honey brown sugar and a black pepper mix. Some clove as well. At 100 proof is when you really get to sense the Brown-Foreman profile. I didn't discern as much caramel as I did with the 86-proof Old Forester during this tasting. The palate has a little bit of viscosity, not much.
The finish is surprisingly short, but the oak and pepper mixture carries through to the finish.
