A few weeks ago I harvested my grapes, cherriesc and plums, crushed them and put them in a couple of fermenters for a couple of weeks. Last weekend I pressed the remaining juice out of the fruit and put it all in a carboy to continue its job. Everything looked good for a couple of days and then last night I found what I am hoping is just yeast, but would like some confirmation. I haven’t seen yeast look like this before, but I am not familiar with this particular yeast. Floating on top looks like large chunks of sponge or upholstery foam. Airlock smells normal, this doesn’t look anything like any molds I have seen or flowers of wine or anything.
I don’t recall which yeast I have in there, just asked for a yeast for a red. I can check when I get home if that helps.
Here is a picture of the stuff in question.
Thanks for any insight you may have.
