I brewed a batch of cider mead. Once fermentation was done, I put it in the fridge to let the sediment settle, and to let it clarify. After a few days, these weird bubbles formed in the sediment, along the edges of the fermentation jar:
Also notice that the sediment above is a slightly different shade than below. I have never had this happen before.
My thoughts: The different colours in sediment are the differences between the yeast sediment and the cider sediment (yeah, some got through). I'm guessing that the bubbles are maybe caused by trapped gas, maybe fermentation wasn't as done as I thought (maybe I need a better hydrometer)?
Has anyone ever seen anything like this? Any suggestions as to what I should do? Should I just stir it up, let it sit, and then bottle it?
