My friend recently ended up pushing his airlock gasket through into his mead and then dumped it out.
It was all sanitized and fine, but he didn't have an extra.He could have covered it with saran wrap or something and bought one the next day. I pretty much was like, what?
Roll with your mistakes or ask questions before doing anything drastic. If it gets infected somehow, then dump it. If your sanitation is good, you shouldn't have much to worry about. That was at least 6 pounds of orange blossom my friend dumped out.
Started brewing February 2012. Still brewing.
