Need roughly 20.5 gallons of water, 14.5 in mash plus about 6 for sparge. Estimate about 6 gallons absorbed by grain, so this should leave about 14.5 left for boil. Only need 13 for pre-boil volume, so could reduce amount of sparge water by 1.5 gallons, but best to be safe. This will give a 1.25 qt/pound ratio during mash. To do a more effective sparge, could use 8-10 gallons and then just do a longer, more vigorous boil.

1/5/2020 4:13 PM over 5 years ago	+9	Other			1/5/2020 4:37 PM over 5 years ago	Fermentation started about 24h after pitching (3 packs of Nottingham, 2 of S-04 rehydrated and pitched into 2 carboys). Required a blow-off tube and had violent ferm activity for about 3 days (making a mess, even with blow-off tube). Fermentation stalled on Jan. 1, so raised temp. A day later, continued to raise temp to 68, frequent agitation of the fermenter, but stayed at about 1.054, far too high for desired FG of 1.029-1.035. Raised temp again to 70F, sprinkled on some alpha-amylase. Next day (Friday morning), added yeast nutrient mixed in boiling water. Gravity is now around 1.040 and steadily declining, with continued slow airlock activity. Will likely settle at around 1.035 this week.

Slight bourbon and oak flavor, will become more pronounced with time. This will need quite a bit of time conditioning to get into its own as it has tons of hop and dark roasted malt flavors that need to mellow. Reasonably thick mouthfeel and beautiful tan/brown head. Very tasty already!
