I'm making a cyser, and it's in the secondary, but the carboy seems to have some sort of residue that's formed on the inside. I made sure to sanitize everything, what's growing inside my carboy? Is my cyser ruined?
The photo makes it look more white and pronounced than it looks in person, fwiw. I think its the flash. Or maybe it went down overnight? Seems unlikely, but idk... It doesn't seem as bad now as it did last night, but I can't be sure.
