6:45 Flame on. Heating mash and Sparge water.
7:14 Kettle strike temperature is 175 °F. Draining to the mash tun.
7:20 Drained. Mash tun strike temperature is 166 °F. I’m going to let it drop a few degrees before doughing in.
7:25 Mash tun strike temperature is 163 °F. Doughing in.
7:31 Mashing at 151 °F.
8:51 Mash complete. Ending temperature was 152 °F. Vorlauff and lauter.
8:45 Lauter complete. Collected just shy of 3.5 gallons. First running gravity is 1.062 SG (1.056 SG at 98 °F).
8:52 Sparging. Kettle Sparge temperature is 174 °F. Mash tun Sparge temperature is 158 °F. Vorlauff and lauter. Second running gravity is 1.025 SG (1.017 SG at 108 °F).
9:04 Sparge complete. Collected a total of 6-7/8 gallons. Reasonably, that puts the first and second runnings at 3-7/16 gallons each. Boil gravity is 1.044 SG (1.041 SG at 83 °F).
9:11 Flame on. Heating wort to boiling.
9:44 Boiling. Waiting for hot break to subside.
9:50 Hot break has subsided. Adding bittering hops.
10:30 Added flavor hops.
10:35 Added Irish moss and chiller.
10:40 Added yeast nutrient.
10:45 Added aroma hops.
10:50 Flame out and chilling.
11:30 Chilled. Whirlpool and let settle. Original gravity volume is 5-7/8 gallons. Original gravity is 1.053 SG (1.051 SG at 74 °F). Target was 1.046 SG.
11:50 Draining to the carboy.
12:09 Drained. Rocking to aerate.
My yeast is Wyeast 1764 Rogue Pacman with a manufacture date of July 9, 2012. According to Mr Malty, that implies 50% viability. I made a 2-quart starter a few days ago, which means I should have about 2/3 of the yeast I need. 🙁 I need to do these calculations earlier. I could have made a bigger starter or used more yeast packs. This isn’t going to be a very good yeast experiment. This is also the yeast that it took 8 days for FedEx to deliver to me, so who knows how stressed it was to start.
So here’s the plan. I need 226B cells. My starter has about 150B. I have 2 more smack packs that should each give me 50B cells for a total of 250B.
1:18 Everything is cleaned and put away.
The fermentation temperature is not set yet.
Sunday, October 7 Kegged. Final gravity 1.016 SG (1.017 SG at 48 °F).
