I haven't checked the gravity yet - need more sanitizer - but I noticed last night that one of my ciders has small little bubbles. Doesn't seem to be much airlock activity if any (but haven't watched it like a hawk) but bubbles accumulating in the carboy neck.

I started this cider in Sept.
Racked once
It's still cloudy thanks to some under ripe apples I believe
pH-3.6
TASTES so great (fave so far)

It's sitting at 12C/53F - which hasn't changed (chance it could have been 51 for a short period with the cold snap)
Used wlp775

I did need to shift the carboy over a bit to make room for another.

Could it be malolactic fermentation or is it just co2 being released?

It could also be MLF...apples have malic acid.. But it could be that as various particles drop out of suspension the CO2 in the liquid nucleates around those particles and nucleation enables the gas to collect and the collecting gas may have enough energy to be expelled from the liquid.
