I've got this on tap now, and it's not exactly great. No flaws from the process, but the popcorn flavour is rather overpowering. I think if I were to repeat this (and I have no real plans to), I'd drop the popcorn to just 0.5lbs.
I won't be at the next two meetings due to other things getting in the way, but I might send a growler along for you all to marvel at its mediocrity
