geri Campden tablets are sulfites. It is k-meta or Na-Meta in pill form- one tablet per gallon. If you havent added any campden/k-meta lately, be sure to add it now. Then add the k-sorbate to prevent renewed fermentation after sweetending. Next sweeten to the desired amount. I let it sit for a few days just to make sure it hasn't started fermenting again. If all is still well and still, then bottle.
