Sunday 29th October - Mashed in at 63.5C. 30 minute infusion before turning turning on the heat and heating to 67.5 for a second 30 minute infusion. Mash out at 71C. End of mash pH = 5.35.
Whirlpool/Hopstand addition added after wort cooled to 80C. Stirring every 5 mins. Total duration around 20 mins before cooling the wort down to pitching temp and transferring to corny fermentor. Saved 1/3 of the 71B starter for future use and pitched the remaining 2/3 at 20C. Fermentation temp should be low. Ambient temp in the basement is currently 18C. So will ferment in the fridge set to 17C.
A crawling fly had got into the starter. Fished him out but hope this doesnt mean another infected batch... Starter tasted very estery, but had a slight phenol whiff to it that really reminded me of the dumped batches :(
OG = 1.059. Approx 20L. Blow off activity observed after just a couple of hours.
Tuesday 31st October - Blow off activity significantly reduced (1 bubble every 30 seconds). Added a small BT DH charge and capped the corny fermentor.
Sunday 5th Nov - Transferred to purged DH keg on top of 7.5 g/L Mosaic
Tues 7th Nov - Cold crash started
Wed 8th November - Transferred to serving keg. pH = 4.69. FG = 1.020(!). 5.1% ABV
Good not great. Phenol(?) off taste still there in a smaller amount? or is this just a fruity ester / champagne / wine yeast style flavour
Rebrew
