Cider vinegar
If your cider has an olfactory defect-or worse, taste- everything is not lost: turn it into vinegar! Simply replace the bubbler on the carboy with a breathable fabric and then forget the container in a corner of the house or attic for at least 6 months. That's it, the trick is done! You just have to get started on the preparation of marinades.
If patience is not part of your qualities, add a few drops of unpasteurized vinegar to speed up the process. As with the kombucha, a mother visible to the eye will form in vinegar. It will be used to speed up your next vinegar.
Many grandmothers confirm that apple cider vinegar is excellent for digestion. Just swallow a tablespoon before the meal. It's also excellent for the day after the well watered watch (this is a youth secret).
