Anyone know what this stringy substance could be inside half of my ice cider bottles? I've attached a picture. It looks like a strand of spaghetti. At first before I disturbed the bottles it was one long string. I clarified it with Kieselsol and Chitosan. Sorbate was added, and 60 ppm of SO2. Could it be bacterial, despite this much SO2, or a protein? It was bottled in February.
Thanks,
Rob
