Notes

Made 2 4L/1# starters

9.5ml of acid - had to take out 1.5g. of acidified water because we overshot the strike temp. so not all of the 11.5g was acidified in the end. Still brought us down to 5.1 - not sure why so low.

Brought the IBUs down from 28 to 25.5 this batch - discuss...

Starting G - 1.082
Ending G - 1.008
Pre-boil - 1.040
OG - 1.046

Got it into the fermenter at about 75 - took it to 55 with glycol chiller over 6 hours. Pitched all starters and will let it come back up to 60. Activity apparent in about 10 hours. Holding firm at 60-61. Was down to mid-teens in 6 days so raised to 68 for 2 days then started the crash - beer at 1.011 or so.
