Brewing a Belgian mocha stout, fermented 2 weeks in the primary. One week ago, I racked it into the secondary onto 4 oz. of cacao nibs packaged by Northern Brewer. Sanitized my secondary fermenter and siphoning/racking equipment as usual. I assumed that the cacao nibs, packaged in the oxygen-barrier foil pouch, would be sterile and ready for use. Was I wrong?
One week after adding the cacao nibs, I have this white powdery-looking mass floating on the surface of the beer. I've only brewed once before with cacao nibs (also from NB, in a foil pouch), and I don't remember anything like this. See attached photo.
Would appreciate hearing from anyone that recognizes whatever this is. Thanks.
