A Toast from CJ in J

I finally did it.

I brewed my second batch of CJ’s JPA.

I did not want to tie up the whole day brewing, since it was Memorial Day weekend, so I got as ready as possible the night before and start as early as possible in the morning.

Here is the recipe as I made it:

I formulated this recipe to produce five gallons (19 L) of beer for packaging. I assumed a loss due to trub of a half-gallon in the fermenter and another half-gallon in the boil kettle. That left six gallons (22.7 L) at the end of the boil. I assumed a boil-off rate of about one gallon per hour, which means I needed seven gallons (26.5 L) at the start of the boil for a 60-minute full-volume boil. I adjusted the ingredient amounts accordingly to achieve the desired gravities, bitterness, and pitching rates. I assumed the use of bagged pellet hops for all hop additions. I use the Rager formula for calculating bitterness and the Morey model for calculating beer color.
