What are these bubbles?

[QuiQuog]

This is a FWK Baby Super Tuscan that finished fermenting on Oct 21st ‘23 with a SG of 0.994. It’s been sitting in bulk since then, with 1 addition of kmeta at 3 months. I was looking at it a few days ago since I’m planning on another addition when I noticed the bubbling. I didn’t degass since I’m planning on bulk aging for a year, so I’m wondering if this could be co2, since the temperature has warmed up lately. I’ve just never seen it this active at 6 months. Then again, I’ve never skipped degassing.

Edit: I guess we can’t post video? Instead, I’ll post a picture of the airlock showing the liquid to one side. The movement of the bubbles looks like the end stages of fermentation. The small headspace is also evidence of the higher ambient temperature.

An increase in temperature would potentially eject CO2 out of suspension.

Could be related to changes in barometric pressure. I don't think it is a cause for concern.

Over a month later and it's still bubbling. I'm not concerned though, I'm just curious. Is it possible that it's still degassing? Could it be something else? I get conflicting information on whether there are visible signs of MLF, like bubbling, but I strongly doubt it's that anyway since I added kmeta at 3 months. It's just hard to imagine that it's still visibly degassing after 7 months.

how much sulphite did you add and what is the wine volume?

I put 1/4 tsp in a 6gal carboy. I guess it's worth noting that the bubbles have stopped at this point.

My airlocks always change level depending on the weather.
