Barrel 20-0468 Has a strong alcohol nose, mixed in with vanilla, caramel. For a 110 proof it was surprisingly mellow. Room temperature neat, was boozy but sweet. Caramel, vanilla towards the front, going to heat, spice, woodsy. Felt it was very balanced. So one bourbon cube impression didn’t change it drastically. Cuts out most of the sweetness on the front end, so now the peppery spice and burn is more noticeable. Seems like it ramps it up a notch.
