1st grain father brew. Started it at the shop, finished at home. Found out that it has a safety switch on the bottom
Based on boiling 9.20 gallonsliters at 1.070 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.078. You were planning on an OG of 1.078 so you are right on track. Nice job!
