My BOMM is a month since pitch. It has been at 0.096 for over a week. I put it on a slow stirplate yesterday until bubbles stopped surfacing. On the stir today (or off, for that matter), no bubbles are surfacing in the carboy, but it's pushing gas thru the airlock at what seems to be a pretty constant rate.
Yes, I know: Airlock activity does not necessarily indicate active fermentation.
So, if the yeast isn't making CO2, where is the gas coming from?
And does stable gravity alone indicate "finished", despite the gas production?
