Let me start by saying that I double checked every one of my readings, and am extremely confident that the readings are not a mistake. That being said, what went on today with my efficiancy?
I brewed Jamils dark mild, set with my normal brewhouse efficiancy of 71%. I checked my "efficiancy into boiler" in beersmith, and it was 104%!! WTF. I ended up with 8.25 gal of wort at 1.031. Like I said I double checked all of the measurements and data entries, and it came up the same. At the end of the brew, my OG was 1.043 (expected 1.033), with a brewhouse efficiancy of 87.5%. That is the highest efficiancy I have ever had.
Some things worth noting:
crush shouldn't be an issue, as I bought three batches the same day, at the same place, using the same mill and the efficiancy on the other 2 were 69% and 71% (which is my avg).
equipment was definitely different on this batch. I followed flyguy's tutorial for cooler conversion on my 5 gal igloo. I didn't want to use my 10 gal since it was such a small grain bill (6.75 lbs). It is using a stainless braid.
I got a new 15 gal brew pot, and today was the inagural run. Having the bigger kettle did allow me to collect more wort, which should have helped my efficiancy some, but I didn't think that much.
So is 104% even acheivable? Logic tells me the only ways were if the gravity reading was wrong, the volume reading was wrong, or the grain bill was larger than entered into beersmith. I anticipated an improvement in efficiancy with the ability to collect more wort, but brewhouse from 71% to 87%? And the 104% into boiler is driving me crazy. I'm happy that my efficiancy improved, but that was one hell of a jump.
Do you guys have any ideas on this?
