Notes

400B cells in 6 gal fermenter.

120sec of pure 02.

10g chalk + 8ml LA to mash, 2g chalk to sparge.

2.5 year old Warrior hops = much lower bitterness than estimated? As low as 25 IBUs.

Significant autolysis flavors - believed to be from sitting in primary for 2 months at high ABV.
Autolysis update - extra yeast in fridge also seemed to kill itself with no extra effort, which makes me think the yeast was stressed to begin with and not the fault of sitting in primary, although it didn't help.
