Notes
Made starter at 3:30 PM on 12/24/09. 150gm DME in 1.5L. Temp at start of mash closer to 151F, dropped to ~148F over 75 minutes. Boiled for about 75 minutes. Pitched yeast at 5:00 PM. Perhaps to cold of a temp (~62F)? Fermenting actively as of 10AM 12/27. Put heater in and temp to 66F. Nothing in blow-off yet. Blow-off very active on 12/28 for entire day. Slowed down 12/29. Temp at 70F.
Took sample on 1/2, gravity of 1.024. Switched to airlock. Bubbles about 2-3/minute, appears to still be fermenting. Yeast still on surface. May need up to 4 weeks in primary.
Kegged on 1/16/10. Some bubbles came from inside siphon (?CO2 coming out of solution versus oxygen). Will attempt to cold condition for at least a month before tapping. First day at 30 psi. Then switched to 14 psi on 1/17. Garage temp probably between 50-55F. On 1/31/10 put in kegerator. Temp is probably around 38F.
Tapped 5/18/10
RIP 9/17/10
