Is the brown foam wild yeast?

[Cdustin22]

This is my first time brewing and im learning at every step what not to do.
I over filled my fermentation vessel and the foam is getting into my air lock can i take liquid out? its been two days since i added the yeast so im not sure if its about to go down. My next question is if i have a wild yeast infection the top of my foam is brown.

Look up “blow off tube” to learn how to avoid, or remedy, the overflow situation.

As for the the brown color; it’s normal. That’s just suspended hops and other trub being pushed up by the vigor of fermentation.
