Hi all,
I am a few weeks into MLF, in the beginning I noticed both my carboys airlock levels showed a positive pressure from inside the carboy, meaning there is some outgassing happening. Now one still shows positive pressure and one negative pressure which I thought was odd.

Is there reason to read into these levels or should I not concern myself with them too much, I was just worried I may have a leak somewhere and I do not want to have any issues with oxidation of the wine.

Thank you all your any advice/help.

John

My vote is temperature change. When I put wines through MLF they are full to 1/2" below the bung. At times when the temps swing upward wine sometimes gets in the air lock.
