Notes

Tuesday 29th September.
Mash start 0830 with 4kg Gladfield Ale malt and 1kg Gladfield Redback Malt at 67C.
Start recirculating at 0925 with HLT temp at 72C. Finish temp 72C.
Start sparge ( water treated with 1 tsp Gypsum, 1/2 tsp Epsom ) and pump to Kettle at 10.10. Fire up gas at 1020 with 20L and collect 31L. Add 15gms Pacific Gem in spider at 1044. Boiling at 1046. Add 15gms Citra and 15gms Mosaic at 1210. Flame out at 1218. Start cooling 1220 Add 40gms Zythos at 80C. 60C at 1225, 44C at 1230, 30C at 1240, 20C at 1300.
22/23 Litres after boil.
Start runoff to MJ Fermenter at 1300 - collect 21L.
OG 1050/51 = 70% efficiency. Pitch yeast MJ36 Liberty bell at 1430.
Light bubbling at 2100. Fast start.
Wednesday 30th bubbling really well smell is good.
Thursday 1/10 at 1500 bubbling almost stopped - add 50gms Zythos as dry hop and give a bit of rotate back and forth to get pellets to hopefully drop and stimulate a bit of bubbling to purge o2.
Sunday 4/10 put into fridge at 5C.
Thursday 8/10 - after a few days at 5C and tasting and smelling slightly vinegary now absolutely delicious. Rack into Keg1 and collect 19L and 2 x 500ml bottles.
Gravity 1020??? Gravity if doesn't drop = 4.07% and goes up .26% for every 2 degree increment. 1018 = 4.33% 1016 = 4.59% 1014 = 4.86% 1012 = 5.12%.
