Also, I don't know what happened, but although my last two lodo no-sparge batches hit 73% efficiency (down from the low 80s with a batch sparge), today's brew was only 63%. Maybe it was the oatmeal.
I still hit 1.053 which will be fine, but I'm seriously considering setting up a 240V RIMS later this year. I'll have to call an electrician and see if that's a possibility.
