I know.. air lock activity does not = fermentation.. change in air temp ect can cause expansion of the beer to cause a airlock bubble. Lack of airlock activity could be just a leaking bucket lid... ect.
BUT.. in my temp controlled fermentation chamber that holds to within 1 deg f I have two 5.25 gal batches of beer fermenting (well I would have thought done fermenting).
Blue Moon clone at day 31
OG 1.052
Todays gravity is 1.011 (temp corrected) with a recipe target of 1.012
and
JG American IPA at day 30
OG 1.055
Todays gravity is 1.025 (temp corrected) No recipe target FG as I made this one up with some help...
I suspect it is the JG American IPA at day 30 that is still working.. but not positive.
Both used blow off tubes in to a glass jar of starsan.. and one of them suckers is still fermenting and blowing bubbles every few hours.
Im popping lids today to get Hyd readings and install standard airlocks.
Though with releasing all trapped C02.... I don't expect air lock activity anytime soon.
I'll check gravity again on thursday and we will see what we see.
The question is.... in a temp controlled fermentation chamber (68deg f ) I can see the yeast doing clean up duty... but active fermentation producing enough co2 to bubble an air lock every few hours?
