Timothy Taylor Boltmaker; supreme champion beer of Britain in 2014. Wheeler recipe; was sad to hear he died recently. Although I tend to prefer Belgian styles, I can't pass up the supreme champion. Got to.
Volumes fully tied down, all steps. Have hit target pH right on the head on my last 3 brews; got that tied down now too. I cheated on the brewhouse efficiency, with 66% in my recipe, so oops, I overshot SG by 5 points. I'll probably start to be more honest with that in future recipes, maybe -2%, just in case. I actually hit 74% brewhouse, and 86% mash.
One other variable I'm just starting to get to grips with, is boil off rate. I boil outside and have been seeing anything between 13% to 26%. I now realise that this is linked to time of year, so almost certainly, ambient temperature. I now realise that to get to grips with this, I must record both boil off rate and ambient temp. Anyway, based on the records I do have, I guessed 14% today and actually hit 13.7%. Yes, very precise, but the point is, I got very close. So I hit exactly 23l in the fermenter.
Can you tell I'm a bit of an analyst?
