Mold at the top of the carboy's neck? (newbie brewer )

[SPARKLE]

7 days after fermentation, I noticed that there are spots of (mold??) at the top of the carboy's neck. Will this ruin the batch?

It is weird because there are no spots on the surface of the cider, Is this the start of an infection?

Doesn't look like mold...looks like krausen from fermentation.

It does not look like mold to me, looks like krausen from the foam during fermentation. Unless there are white, blue, green, red or orange "furry" spots your probably ok.

I would clean the airlock as it looks like krausen in that too. It may plug the airlock.

You could carefully clean the krausen if you want to. Use a sanitized paper towel. I would suggest its not really necessary the krausen should dry.

That’s pretty normal. I don’t see anything worth worrying over.
