There is floating debris in my mead—Is this a cause for concern?
Some context: I fermented honey water with Red Star Premier Blanc wine yeast, nearly 4 weeks ago. Two weeks ago, I transferred the mead into another carboy for secondary fermentation, added in toasted oak chips, and a Campden tablet. 1 week ago, I removed the oak chips, and transferred the mead into a new carboy. The mead still has not cleared up, and I just noticed some floating debris with bubbles. Is this just yeast that got kicked up, and is this normal? Thanks for your help!
