I brewed Orfy's Hobgoblin yesterday. I had a problem with my mash. I started with 3.5 gallons @ 165, added the grains, expecting to stir it down to 152, and the mash dropped to 138!
I had put the grains in the freezed because they had some bugs (not buying from that supplier again.) I completely forgot to take that into account when I started my brew day. So, I put freezing grains in my MLT, dropping my mash temp too low. Stupid!!
So, I removed 1/3 of the mash to the kettle and brought it up to as close to 170 as I dared, and then re-added it to the MLT, stirred and checked. I got 152 and it held for the full hour.
So, I'm not sure if this can be considered a decoction or not, but what are the implications of my screwup? Should I be okay? It's already blown off and made a mess, so I know it's fermenting well.
