Everything I read says it is a micro-derm infection- white, powdery membrane floating on the secindary.
It was just a couple bubbles, with a white powdery insides look, in the third time I used the yeast, but it was/is still good beer. Now, after 2 weeks in secondary, it is a film over the whole top, streaks extending up the sides. I sucked some of the top layer into a glass to sample, not good. I guess I'll dump it. Or maybe I'll rack carefully from the middle and sample it agian, nothing to lose, I can always dump the bottles and wash them. I already dumped the saved yeast cake.
I didn't do any thing to save the yeast betwen batchs except bottle some of the cake, as if it were beer, and then refirgerate the few weeks 'til makeing a starter for the next batch.
But, just what is micro-derm? I can't find any scientific use of the term, except for facial scrubs, and homebrewing. Is it a contracion/abreviation of dermatophytes, nail fungus? er what?
