a fantastic point @ironshield! i will update the post now, but will also answer you here: we use apple cider vinegar (with the mother still in it; just an organic brand that hasn't been pasteurized, although pasteurized will do). that's just what we have on hand. you can also use rice wine vinegar or other vinegars you may have (balsamic for an adventurous palate, though it may overtake the local plants). Vinegar used for cleaning isn't recommended, but the other vinegars at your local grocery in the food isle will likely all work!!

Thank you! I'm sure cider vinegar would taste a lot better! @ironshield
