Neat: Comes in with the rye heat, and lingers for quite some time with that spice in the finish. Slightest bit of ethanol on the nose. 1-2 ice cubes: Complete game changer. Nose is butterscotch. Taste is caramel for days. But still finishes with that longer lasting rye spice. I typically do neat for anything less than barrel proof...but honestly I enjoy this more with a little water or a couple small cubes.
