Thank you to everyone for the replies. We just brewed a brown yesterday and hit all of our target gravities. The problem we were having with efficiency (55% the last few batches to 70%) seemed to stem from sparging way too quickly. Went from 5 minutes to 1 hour.
I believe the primary problem...
Thank you for the quick responses. Next brew we do we will carefully measure volume, let the wort cool before taking SG reading, carefully noting the temp, and fully mixing before taking a sample. And go from there.
Happy brewing
Thank you both for the response. I agree that temp could have been a factor, but to be off that much is odd. But my 2 concerns are. 1) I checked both measurements with a refractometer;has been calibrated. 2) my efficiency would have to be horrible to use that much grains and still come out that...
Help to figure out why our ending boil gravity is the same as our beginning boil gravity. All grain. Quite confused. All gravity was checked with hydrometer and refractometer
