used 3 month old yeast, didn't start by tues, so added new pack of us05 tuesday afternoon. fermentation started Wed.
Based on boiling 7.40 gallonsliters at 1.044 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.050. You were planning on an OG of 1.050 so you are right on track. Nice job!
