Mash Guidelines

Amount	Description	Type	Start Temp	Target Temp	Time
3 gal	add pumpkin puree with strike water.	Strike	169 °F	155 °F	45 min
0.75 gal	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

Notes

Reusing yeast from a previous brew.

Add pumpkin purée to mash with grains.
Mash 90 minutes at 153F.

Boil 75 minutes, add pumpkin pie spice and maple syrup at flameout with remaining hops.

Ferment at 51. Add vanilla beans for lagering.
Plan to lager for about 11 weeks to have ready for season.
Honestly, I plan to only add 1 vanilla bean for lagering. 3 beans for 11 weeks seems like too much vanilla.
