Infection fermenter

[Jan.vidal]

Hello,

A couple of days i found this behind in my fermenter it seems like an infection.
But iam not sure.
It is the first time i used the fermenter i cleaned it with pbw and sanitized it with star san but no passivation. The krausen ring looks black.
And under the krausen ring it really looks like an infection. I sanitized very well.
What do you guys think?

Sorry for my bad english i'am from belgium

The black krausen ring is a fairly commonly reported thing with stainless steel fermenters, particularly new ones. It may be due to some manufacturing residue. That said, I have two stainless steel fermenters, but I have never seen this in mine. I did clean them very thoroughly before their first use though.

And under the krausen ring what does it look like?

It looks a little odd, but it might just be yeast with some of the black, oily residue mixed in. How does the beer taste?

I think it didn't taste odd
I bottled it either way. But under the krausen is were i worry a lot about.

Was there a pellicle (like a skin) floating on top of the beer when you transferred it?

The black ring would concern me more then the possibility of a pellicle. I don’t know what that could be, but in 15 years of brewing I’ve never seen one.

It looks like the residue from oil they put on these ss fermenters to me. Did you do a hot water rinse after you soaked in pbw?

BTW- welcome to HBT !

This is how it looked liked at the top but this is after racking the beer

I'm no expert, but that doesn't look good. How does it smell?
