Ok so I just brewed a 5 gallon Caribou Slobber all grain batch two days ago (actually yielded 5.5 into the fermenter so I'm happy with that. I didn't buy the kit from Northern Brewer I just went to my LHBS and got exactly what I needed.

There's the grainbill and my setup is BIAB no sparge with a pump recirculating throughout the whole mash time, on the burner, along with me stirring a lot too. I started with 7.5 gallons of strike water and after my 60 minutes at 153 were done I lifted the bag out and squeezed and got a preboil volume of 7. Only lost a half gallon to absorption. Anywho...after that my volumes and numbers don't matter because I'm posting this to question my conversion efficiency. I was astonished to see that I got a preboil gravity of 1.050. After I plugged it into brewersfriend.com brew house efficiency calculator it says I have a conversion efficiency of 99% I kept rechecking it and refreshing the page and sure enough...99%. Any one have this happen? View attachment ImageUploadedByHome Brew1447438371.584249.jpg
