I just brewed a sour mash Kentucky Common yesterday. I mashed in 50% of the grain bill at 150F on Tuesday, and let sit for 48 hours. Yesterday morning, the temp was 87F. I brought the remaining strike water to boil, and added it to the mash tun, which brought the temp up to 134F. I got my 3 gallon pot out, drained about 2 gallons from the mash tun into the pot, and brought that to a boil. Then added it back to the mash. The temp was almost dead on, at 151F. From there, brew day was just like any other.
Fun batch of beer, I just hope it turns out good.
