I have two batches of cider that need more flavour, and being a juice producer as well I have quite a lot of pasteurized apple juice from last year still. I have tried adding a little juice to the two ciders, and they do become quite nice with only a small percentage of juice added. Both have been sitting for too long before first racking, one spontaneous fermenting and one with EC-1118. Can I add pasteurized juice to the cider after sterile filtration using 0,2my plate filter and get a stable product? I plan to carbonate and bottle in champagne bottles.
