Ok everybody. Here's the deal. I brewed a beer two days ago that I thought would easily end up in the 1.080 range. It's a cross between the Midwest Power Pack Porter and Oatmeal Stout. They milled the grains, and I ran them through my newly built corona just for extra measure.
This is what I ended up with going into the fermenter. I mashed with close to 10 gallons at 164 to get the mash to 150. My thermometer seemed to be slow to read, and only got up to about 147. I mashed for about 80 minutes because I forgot to put the oats in for about 20 minutes. First running during fly sparging were 1.084. I sparged with 6 gallons at 170. I missed final runnings because it finished draining before I realized it. I had about 12 gallons at the start of the boil. I added the pound of brown sugar about 10 minutes before the end of the boil. I ended with 9.5 gallons in the fermenter at 1.068. According to that calculator, thats only about 55% efficiency into the fermenter. What gives?
