Mold or yeast?

[powerpunk5000]

Fermenter was sanitized using starsan. Dry yeast was sprinkled in mouth of carboy

Looks like mold or other unintended growth to me from the photos.

Never seen yeast do that but I suppose it is possible.

Really? It showed up only 2 or 3 days after it was brewed. And the carboy was sanitized well

A moist food rich environment so yes... Two or three days is a long time. Consider how rapidly the yeast took off.

Could have been any number of causes if it is mold or some other bacterial growth. The stopper, a funnel or other device used to get the wort in the bottle, it was touched inside, already contaminated wort going in the bottle too even just the air.

Could be wrong of course. I'm not there to get a better look. Maybe someone else has encountered something similar and can shed some light on it.

Everything was pretty well sanitized I thought. But I took a paper towel and soaked it and wiped it out regardless. It didn't have a funky smell to it so I'm not sure. It also didn't appear to be fuzzy so I think it was just yeast, just wanted a 2nd opinion

Hard for me to say. Does it look fuzzy at all? I have never seen that before and I fermented in glass carboys for many years.

No it don't look fuzzy, do you sprinkle dry yeast right in?

I do. Did you shake it after you added the yeast? It could just be some yeast growing on the rim of the carboy...hopefully.

That's definitely yeast and not mold. Some of it got stuck to the side when you sprinkled it.
