Something that looks like yeast in my airlock

[SanAntone]

Any thoughts? Beer has been fermenting 4 days and I just notices some yeast looking substance in my airlock but there wasn't beer everywhere so it doesn't look like an overflow.

Yeast.

You had just enough krausen at highest activity to push a bit of foam / yeast into your airlock. Really common.

It's probably...yeast.

Assuming you did what you should (and put either vodka or starsan-water in your airlock), it shouldn't make too much of a difference. Clean it out and pop it back in.

Sometimes just the CO2 pressure is enough to push some yeasties into your airlock, which then to stick together in the liquid...

Thanks! That's a relief
