I recently made a 6 gallon batch of blueberry beet wine. Fermentation went fine, when spg dropped to .994 I degassed added sorbate and metabisulphate, then I added super kleer. I noticed in the carboy after 2 days heavy skum and crud formed at the top of the car boy and flowed out the airlock? This is the first time ive used super kleer and have never had this happen before with sparkloid powder, any thoughts?
