I just started my first simple cider. Just juice and notty yeast in there.
Its been fermenting about 48 hours, and already seems to be calming down. Still bubbling quite a bit, but the foam is dying down.
I used a 6.5 gallon carboy for 5 gallons of juice, for room if it bubbled up, but that didn't happen, so there's lots of room at the top.
I was planning to keep things in the primary for 3 weeks. Is this risky with all that space? Should I grab a 5 gallon carboy and rack to it after a week or so?
