Brewed the day after the "Rapture" May 21st. A big, cellar-able beer seemed appropriate for such a near miss with the end of days.
In anticipation of massive blowoff, I split the batch into two primary fermenters for extra head space. Each 2.5-2.75 gal half got its own 6 gal carboy, and within 36 hours each vessel had 6"-10" high krausen. After about a month, each half was holding at 1.030 so I racked them together into a secondary vessel for bulk aging and added ~2 ounces of medium toast oak cubes that I'd soaked in bourbon for 2 months. I wanted less bourbon than say KBS, but enough that its noticeable.
I was really happy with the gravity sample: very complex roasty, chocolate, coffee, viscous like oil, roughly 12% ABV. Bottling this one in the fall, then I may take it to my folks' place to hide it from myself until next fall.
(split fermenters about 12 hours after pitching)
