Wow the whole HELP QUICK thing really worked didn't it?
I took your guys advice and pitched it. Like I said, it smelled like yeast with no weird funky smells, and the upside is that this growler is my "yeast starter" growler so nothing goes in there except yeast. Though I do store it open to the air, which I won't do any longer, and haven't used it in a month or two, I'm hoping that all other good brewing practices prevail and I can have a batch of great beer.
Thanks for the help guys!
