Comments

Added lactose at 15 minutes until the end of the boil. Cooled to 68°, racked to primary, and pitched 5 oz. yeast from a slurry (April 5, 2008).

Spilt this batch into two at secondary. Racked one as is. To the other, 6 cups of strong Sumatra coffee was added. Obviously not attenuated fully yet, so it was moved to a warmer room (April 12, 2008). Fermentation seemed to peter out at 10 days. Added 10 crushed tablets of Beano to get things going again (April 20, 2008).
