Quad-berry wine infected.

[Pyg]

It has been years since I made berry wine.
I have been checking the wine daily and squeezing the berry bag.
Today I noticed some big bubbles on my krasuen.
If this was in my batch of beer I would be worried.
I did use a combo of home grown & store bought berries (black-blue-straw-rasp)
Is this an infection? Or just gas bubbles?
Can I just hit with a dose of K-meta/sorbate when he ferment is done?
I thought wine was more tolerant to infection than beer?

This looks perfectly normal to me.

It looks ok. If you're really worried, if it's been about 5 days, you could squeeze the bag completely and rack to the carboy now, if the SG is 1.030 or under. That would ensure it would be better protected.
