Soo I have several jars of kombucha I made almost a year ago. I stored them in the fridge (though recently my roommate said I should get rid of my 'pets' and so they've been sitting outside for almost a week now (in mason jars)). They don't look contaminated (no greenish/weird colored mold), but most smell strongly of yeast in a not good way, even when they were in the fridge. If anyone has worked in a fly lab, it smells strongly like the fly food (which I think is brewer's yeast??) and made me nauseous thinking about that. Should I just chuck them? I feel bad since I've stored several mothers in some of the containers, and they still look as they did a year ago, really thick and healthy :/ Should I just start with new SCOBYs? Are they contaminated with 'wild yeast' or other random bacteria I can't see? Thanks.
