I bottled this about month ago and now I have a white film ring at the top of the bottles. These have not been pasteurized. No idea what this is. ideas?
Kinda blurry but too me it almost looks like micro bubble foam like in a steamed milk for espresso based drinks.
How long have they been bottled, have you opened any?
How did you sanitize these bottles? And is every bottle like this? Last time I had film like that it was an infection (did not affect all my bottles - so I assume I had some that were not completely clean).
I would open one and try it to make sure you don't have vinegar.
My bottle conditioned cider also had this white film although not nearly as bad as what you have pictured. A few swirls and it wasn't noticeable when drinking it and it still tasted great. I cant tell if bottles from the keg have it too but they also taste amazing.
