There is a layer of foam on top of a cranberry wine I'm making that's been
there for 2 days. Usually I'm finding this foam only lasts about a day for
most of my kits (this one isn't a kit). Am I at a risk of something growing
on top with all this foam? I didn't put any bentonite in at the start,
should I have? Is it ok to stir the foam in? Thanks.
