March 9th, 2011: Murderface v0.1

Ingredients and Batch Size

Fermenting Log

  • 03/09/2011 23:15: Sugar has been dissolved and diluted into 2x 12.5L. 3kg of sugar each batch. Sean C
  • 03/10/2011 00:15: Specific Gravity of Murderface-1 = 1092 (target = 1090). Sean C
  • 03/10/2011 00:15: Specific Gravity of Murderface-2 = 1091 (target = 1090). It is thought that the specific gravity is off a bit due to temp only (27C & 28C). Sean C
  • 03/10/2011 00:15: Me is tired. And me forgot the yeast. Me is too tired to go home and get it and come back and pitch it, so I'm a gonna let it sit for the night. Sean C
  • 03/12/2011 19:00: Yeast was dosed to both tanks (90g total, 45g each tank). Tank Murderface 1 appears to be darker than Murderface 2, and I can't get some of the chunks of yeast to dissolve. This may be because it took awhile to pitch into tank 1. In the future, pitch yeast and start stirring real fast bitches. Sean C
  • 03/12/2011 19:00: Murderface #1 temp: 68F Sean C
  • 03/12/2011 19:00: Murderface #2 temp: 69F Sean C
  • 03/14/2011 18:00: Murderface #1 temp: 72F lilia (and yeasty! Looks like bad disso @ the beginning didn't do many bad things Sean C)
  • 03/14/2011 18:00: Murderface #2 temp: 74F lilia
  • 03/16/2011 2:00: Murderface #1 temp: 72F lilia
  • 03/16/2011 2:00: Murderface #2 temp: 72F lilia
  • 03/17/2011 00:10: Murderface specific gravity = 990. Close to done! Sean C

March 2nd, 2011: DAVROS v0.1

Ingredients and Batch Size

  • Yeast type & origin: Gert Strand, Black Label (Malmo, Sweden)
  • Theoretical %ABV: 14-17%
  • Sugar Source: C&H Cane Sugar
  • Target Size: ~25L

Fermenting Log

  • 03/02/2011 20:05: C&H Cane Sugar has been dissolved and diluted to 2x 12.5L. Temps: 24.5C, 25.5C. Confirmed ready to pitch yeast.
  • 03/02/2011 20:50: Yeast was pitched and shaken to dissolve into a cloudy solution. Specific gravity of each tank = 1.090 (exactly equal to yeast maker's recommendation).
  • 03/03/2011 23:59: Davros tank 1&2: 72 degrees Miloh
  • 03/04/2011 13:13: Davros tank 1&2: 72 degrees Miloh
  • 03/07/2011 00:01: Davros tank 1&2: 68 degrees Miloh
  • 03/08/2011 20:35: Davros tank 1: 67C, specific gravity = 984.5 (target range = 984 - 987). Its done! Sean C
  • 03/08/2011 20:35: Davros tank 2: 67C. specific gravity = 984.0 (target range = 984 - 987). Its done too! Sean C
  • 03/09/2011 22:35: It was attempted to filter Davros through a medium porosity fritted glass funnel. Filtration was so slow that it was unbearable, and little clearing was taking place. It was left unfiltered, and will be cleared instead using a flocculating agent. Sean C
  • 03/11/2011 19:00: ~1/4oz. of Polyclar 10 (slurried in 1 cup warm water) was split between the two Davros tanks in order to speed up the clarification process. Visually, it appears that the yeast is slowly settling. Sean C
  • 03/14/2011 18:40: zomg! Its clearer-ish! Probably will be OK enough for Wednesday. Tastes like communion wine on steroids (like a super-tanked Jebus...I think that's a good thing). Sean C
  • 03/16/2011 21:00: Filled 22L RBF with ~12L wash. Wash is still hazy, but I'm sick of waiting. Should heat @ 90% power on both variacs to avoid waiting all day to heat. Expect ~1hr. Sean C
  • 03/16/2011 22:30: Column has equilibrated, and distilling has begun @ 65% variac power. Sean C
  • 03/16/2011 23:40: ~600mL distilled. Sean C
  • 03/17/2011 01:00: ~1200mL distilled. Specific Gravity = 824 (87.5% ABV). Stopping distillation, retaining tails in 22L RBF. Still ~12L wash remain to be distilled Sean C
