1st time brewer:
It's been 6 hours since I added the yeast and I'm seeing lots of foaming and seperation of my pear bits from the rest of the ~~mead~~ melomel. Should I be concerned?
I don't have experience with mead/melomel. But it looks like you have too little headspace? For beer I would leave 1/3 of the vessel for headspace so the foam doesn't go through the water lock. I think the seperation is normal
