What I was looking at is at 30 ibus, it's a 1:1 bu:gu ratio, which is IPA level ratios.
My comment about the smoke is that smoke tends to intensify bitterness and adds a bit of astringency (further increasing that perception of bitterness).
I know you brewed it already at 27 ibus, which is a .9 bu:gu, and a step toward what I was thinking. I'm sure it will be good, I was just throwing out what I thought might help take it up a notch, that's all.
Prosit!
