Notes

Brew Day 17.3.2019 - St Patty's Day!

Collected 12L of wort at end of boil. Required 4.5 bottles of the Aquina, leading to slightly higher sulfur content than desired.

OG 1.061 short of the recipe, which called for 1.065. This is surprising since I also put in a bit more DME than my recipe called for. I must have left quite a bit in the grain bag. But I'm surprised I didn't get more from the sparge.

PH of wort was 5.45, fairly close to the expected mash PH of 5.5.

Temperature readings
60: 155.1
52: 156.2
44: 155.3
34: 155.7
26: 151 -> at this point I applied heat
20: 155
7: 152 -> at this point I applied heat
0: 153.3
