I am new to mead and I am only about 6 weeks into my first batch. A white frothy substance started to form on the surface of my mead and I was told by someone that works at my local brew store that it is mold and that I should rerack the mead asap leaving the mold behind. As soon as I bagan siphoning the mead out some of the mold started sinking. Not knowing what else to do I put some crushed campden tablets in the second carboy with the mead. Should this prevent future mold from growing?
