Problems with mash temps. used 13.88 qts at 161 F added to 9.25 lbs of grain (71F) resulted in 147F (liquor may have cooled during mash in, add faster next time) added 4 more qts at <161 resulting in 149F. Added 2.3 qt boiling water to reach 151F (math said to add 1.3qt). pH 5.2
Sparged at 160 (15 min rest) by using 2 gal boiling water. Stuck sparge due to low sparge water temp. Possible hot-side oxidation during sparge by constantly blowing in output line of mash tun to unstick sparge. Sparge pH 5.7 (used tap water)
Used a 2-qt yeast starter with 6 oz DME and .25 Tsp yeast nutrient (71F). Pitched fresh yeast to starter 23 hrs before pitching starter to wort. Ferm started in 6 hrs.
Tastes Excellent. Nice body. Good balance. Sad its gone. I saved 3 bottles for competition.
Base beer for future Milk stout, Coffee Stout, and Cherry Stout. Hence the name Primordial. Still just a great simple dry stout by itself.
