Notes

Brewed 07/18/2019

Mashed at 152 F. Had to stir for 5 min to get down to 152 F from 153 F. I had to mash around 1 qt/lb to fit water and grains in the kettle together.

Cooled to 64 F, pitched, and let rise to 67 - 68 F. Fermented at this temperature for two weeks. The beer was crashed for a couple of days @ 38 F, then transferred to a serving keg. Beer was kegged 1 day @ 30 PSI, 1 week at 12 PSI. Targeting 2.5 vol as carbonation will be reduced slightly when bottling.

-------------------------------------------------------------------------------------------------

A quick half-pint taste was very good after only a few days in the keg. The beer has notes of bitter chocolate. The bitterness may fade slightly with time. For the next batch I might reduce IBUs to low 60s.
