Eruption in fermenter

[Conservidave]

This is the same batch of beer that i posted with no activity for two days. Four days after i pitched yeast and had a gravity of 1.012 wednesday, i come home from work thursday and find the air lock full of what looks like yeast and trub with the same splashed on top of the fermenter lid. I have used US-05 in many of my beers
and it usually finishes in 3-4 days but i've never seen anything like this. Im fearing i have a wild yeast infection or worse, bacteria. Any thoughts.......?

Dave,

Smell it first, and if it is okay taste it. You are probably fine.

If it tastes like vinegar it is acetobacter, which converts alcohol to acetic acid (vinegar), but I kind of doubt it. I bet it smells fresh and bready, which is what the yeast should taste like. RDWHAHB!

Warm it up to about 70° and give it a swirl.
Walk away for a week and then it'll be ready to bottle.
I'm sure your beer is fine.
Yeast has a way of taking care of things.
