Brewday Notes:

Hydrometer reads 1.02 in tap water. Subtract .02 for adjustments

45 g / 100ml starter with WLP677 in sous vide at 40C for 4 hours before starting mash

2.2L to 58C in yellow stock pot. Strike temp: 52C

Heated 2.2L to 88C in separate pot
Strike temp: 66C (yeasties was about right, brewtarget underestimated!)
pH: 5.67
After 15 minutes, pH reads 5.68. Added a few drops lactic acid, dropped to 5.52

Refractometer reads 10.1 or 10.2 after 30 mins (corrected: 9.5°, SG 1.038)

Apparently I was supposed to do a beta-glucan rest at 43C for 30 minutes, not a protein rest at 51C. Hmm.

Batch sparge in 2.0L @ 90C, then top up to 7L
Refractometer reads 12.3 after 60 minutes (corrected: 11.59°, SG 1.047)

Exactly 5L out of 6.4L put in. 1.4L absorbed in 1140g grain.
10.1° plato final runnings (corrected: 9.5°, SG 1.038)

Topped up with 2L to 7L boil. 8.6° plato boil gravity.
Hydrometer reads 1.034, corrected is 1.032. (yeasties and brewtarget predicted 1.032)
8.6P == 1.0343. Correct would be 8.1°P. Wort correction factor 8.6/8.1 = 1.0617 (read from photo using first line with blue tint)
