I currently have 6 gallons of apple juice and yeast fermenting away for the last 6 days. We did not add campden powder at the start or anything else. Please could someone help me with the next stages?? Do we wait for the bubbles to stop and then take a gravity reading? Will I add campden powder after fermentation? How will I bottle the cider what's the process and what needs to be done??? Total newby and really in meed of some help. Don't want to mess it up. Thanks
