Mash Guidelines
Amount Description Type Start Temp Target Temp Time
12.5 qt add pumpkin puree with strike water. Strike 169 °F 153 °F 45 min
3 qt this addition is mainly because of the crappy way my MLT holds temperature. Expected about 11 degree loss after 45 minutes, adding here to bring back to 153F for second 1/2 of mash. Infusion 212 °F 153 °F 45 min
5.25 gal estimate 4.75g needed to hit pre boil volume, adding 5+ so MLT doesn't run out during sparge. Grain bed will collapse. Fly Sparge 185 °F 169 °F 50 min
Starting Mash Thickness: 1.15 qt/lb
