I just went into my guest bathroom where I have 3 batches fermenting away and noticed the thick smell of fermenting beer. My first thought was that one of them had started back up again vigorously, but upon further inspection I discovered the lid to my Christmas ale had completely popped it's seal. About 36 hours ago I took a SG reading and I am almost 100% positive I sealed the lid up, but now I am not sure.
I took a look inside and saw that the krausen was gone, but there where lot's of tiny floating white spots that look suspicious to me, check out the link below for a pic.
Take a look here
I'm sure it's nothing, but if there is a problem I want to brew a replacement batch right way. Thoughts? Could this be an infection? Thanks for the help.
