I contributed to this campaign on Indie gogo. The fermenter now has roughly 7.9 gallon capacity. My question is about ideal volume to put into this fermenter. I have been using 6.5 gallon buckets with 5-5.5 gallons of wort in them. Can I safely just increase my batch size to leave roughly the same head space? Basically, what would be the maximum volume you would try to ferment with 7.9gallon max capacity? Assuming that my BruGear boil kettle shows up soon, once I have both, I can have a batch size up to and beyond the capacity of this fermenter, and with some of the recipes I have been making, I would like to get a little more out of a brew day. Any thoughts you all might have would be most appreciated.
