The wort before boiling was 1.046, I have forgotten to measure it after brewing. That was late Saturday, by mid-Sunday it was at full swing with Safale US-05. I came back after three days later to find airlock pretty still. Measured today - 1.010. I think it's not normal, but can't see what I need to adjust right now. The temperature is 22C, nothing extraordinary. Following a series of setbacks with stuck fermentations, I have aerated the wort with a fishtank air pump before seeding the yeast, but I don't see how this could have speeded the fermentation so much. Should I let it be and, seeing no change in SG in three-four days, just prime and bottle? Or try and drive SG lower? I saved a bit of dry yeast, does it make sense to propagate this in a bit of wort and sugar and add to the barrel, seeing that 1.010 may be a bit high in case it decides to resume the game in the bottles?
