Pils is lagering, I'll keg it in a couple of weeks. But I'm confident enough I brewed another yesterday with the same 153°F/170°F program. Once again, excellent yield, same iodine test result. I think I gave both a couple extra minutes at 170, and this time I didn't even keep the sparge temp up to 170 and everything looks good. I'll report back here when I tap it!
