This cider should be refrigerated for longer-term storage. It should keep for one year refrigerated—check for signs of spoilage, such as mold or off-smells. It may keep unrefrigerated for a short period (up to a few weeks), but the extra liquid from the pomegranate and oranges can dilute the vinegar enough to allow microbial growth. If you are making the recipe just for yourself, I recommend using a fourth of all the ingredients (yielding about 16 ounces [480 ml] of fire cider, or 1 pint).
