15 gallons of honey maybe you mean lbs?
I've got a mini brew of this on, just in a 2l plastic bottle. 1.5lb of honey, no tea (couldn't find it either), 5 fireballs in secondary, and I'm gonna put a cinnamon stick in it shortly. I imagine it will taste rank, but it's mainly for a friends birthday in June so hopefully all goes well!
I look forward to hearing how your 5gl brew goes!
