Batch 13: Brewed July 7, 2023. OG: 1.041 FG TBD. ABV TBD%.

The OG target was 1.07 to 1.076. Very disappointing actual OG. After reading many home brewer posts, my best guess is that too little mash water was used (~2.5 gallons) and too much sparge water (~5.25 gallons) to get to the 7 gallon start boil volume.

Adjustments planned for next batch:

1. Start mash with at least 5 gallons.
2. Measure gravity during mash. Continue at 15 minute intervals until gravity increase stops.
3. Mash 1st 30 minutes at 152F.
4. Mash 2nd 30 minutes at 154F.
5. Mash remaining time at 156F.
