Mold or fermentation not touching the edge of the carboy

Your Mold or fermentation is not touching the edge of the carboy due I would imagine to the dished bottom or side form of the carboy, which is forming the interesting looking krausen. Looks like yeast ...

Dark liquid floating in secondary fermentor

I'm reasonably certain its beer ;) Even a pale ale looks dark in a carboy when it clears. Your yeast is settling to the bottom and in that process the beer at the top is clearing. But this beer is ...

Primary Fermentation - Mold or Yeast by product?

I was once told that a general rule is any white infection is salvageable as a sour if you so choose, any green must be dumped. Personally I hate sours and will dump all infections, and that's ...

Mold on Cider is it unsafe after boil

It's difficult to know for sure. There are many, many kinds of mold out there, some are harmless, and some are toxic. I'm hoping someone can chime in who knows more about mold than I do, but here ...
