American IPA – All Grain


General Info

Formulated to be similar to Anchor Libery Ale. Not strictly according to style - OG and ABV levels are below the BJCP guidelines.


Single infusion mash. Pitched yeast from my stash. Racked to primary and took OG reading. I’m a bit disappointed in the efficiency I achieved this time around. Next time, investigate options to boost efficiency - possibly a better base malt (April 21, 2007).

Racked to secondary and added dry hops (April 29, 2007).

Racked to keg and added 1/3 cup of corn sugar to prime. This one will be "natually" conditioned in the keg, a first for me. We’ll see how it goes. The hop aroma was very evident and, I must say, mouthwatering when I was racking to the keg. Took FG reading and set in the basement to condition cool for the next three to four weeks (May 9, 2007).

Notes for next time:

  • Increase the crystal malt to adjust color. Needs to be a bit more on the amber side and no soooo pale.
  • Increase bittering hop addition and dry hops.
  • Increase base malt and/or add Munich/Vienna for more body. Dextrin would also work.
