This is a clone of Stone Goto IPA. The recipe was taken from Jennifer Talley’s book, “Session Beers”.
Overall this turned out to be good beer but did have some issues.
- It was not bitter enough. Relative to the original , this brew did not have the same sharp bitterness. I found the addition of some isomerized hop extract made a significant improvement.
- Needed more dry hops. After a couple of weeks in the keg after dry hopping, the aroma significantly decreased. A second dry hop addition brought the beer back to life.
- Darkening. This is not the first time I have seen highly dry hopped beer turn dark. I believe oxidation to be the problem
- The desired Mash-in temp of 68 actually turned to be 72. This dropped to 68 over the course of the mash but it is a problem. The beta-amylase enzyme converts between 54-65 which ,means I probably only converted the alpha-amylase. This could account for the poor efficiency and chill-haze that I am seeing.

Notes
| BREW ISSUE: I should preheat the sparge water before the end of the mash. It would save a lot of time. SOFT ISSUE: Kettle power still not being sent to the client periodically. SOFT ISSUE: No boil progress displayed SOFT ERR: Gravity not showing on graph Removed 7 samples (700mL) HARD ERR: Flow Fermenter In seems broke. HARD ERR: Is kettle outlet temp in the right spot? Dry hopped on 4 June @ 2000. |
