I'm about to start my apple mead. Yesterday I mixed everything up for this 3 gallon batch and added 3 SMS campden tablets. After 12 hours I added the pectic enzyme and not it's 12 hours later and time for the yeast. When I opened the bucket there was a bubble looking thing in the center. It doesn't smell bad but call me a noobie but I just want to make sure this isn't infected. Could this just be from stiring in the pectic enzyme or caused by the pectic enzyme and/or campden tablets?
I'm going to pitch the yeast and give it a whirl but I figured I might as well ask otherwise I'll find out after a while how it tastes.
