I'm afraid that I may have a bit of an issue with A.Niger in a batch of mead.


Can someone ID the culture with these photos?

Thanks in advance.

Looks like yeast foam to me. I get that about every third batch. It does no harm, just rack and leave it behind.

My rule of thumb is that if it doesn't smell or taste bad, it isn't infected.

Many thanks to ScottS and Oscaar for taking a look at this for me.

I was horrified to find these floating in my carboy, yet puzzled because there was no "off" odor. When the foam or whatever showed up, they were all very symmetrical with a very distinct six pointed star surrounding a distinct central circular formation.

I was afraid I'd done something badly in my equipment sterilization.

Many thanks again. I'll let you know if things change significantly with it.
