I bottled a stout quite a few months ago that didn't turn out quite right so I've let it sit for awhile hoping it would get better. Today I grabbed a bottle and noticed a whiteish ring around the inside at the top where the beer level is. I looked at the rest of my bottles and they all have it. I swirled one around and pieces of the ring came off the bottle and were floating in the beer. It seems odd that it's in every bottle and only around the top where the beer stops.
Any idea what this is?
