I am an amateur brewer just cooked my third batch ever three days ago. This time with a couple of friends (which also bought the ingredients from a place I haven't before), so this time I used a different recipe, the one the new store gave us. That recipe had A LOT of sugar in it, and so as I feared, after one day in the bucket, due to extremely violent fermentation about a liter of mead was spilled, probably with a big part of the yeast. I see some signs of fermentation although it doesn't look very active.

What should I do? Is the batch ruined? Should i just wait and see?

Thank you!
