Decided to use Columbus as the bittering hop. Last time I brewed this I mashed too high and only used Citra hops. So trying a slight variation.
The IBU has come out far too high on this calculator. Was looking for 65. See how it turns out.
The OG came out at 1080 which is far too high so boiled a litre or water and let it cool then added to the fermentor around 2 hours after pitching yeast. Took another OG reading and came out at 1070 (better)
Added Gypsum to last 10 mins of boil. My water is quite soft.
Mash temp was 155
Fermentation temp 64-68. I don't have any temp control at the moment so hopefully stay around that.
