If you make pickles, you may find that you have leftover pickling brine. Can it be reused? That depends on how it was originally used.
If the vegetables were soaked or heated in the pickling brine prior to filling the jars, it CANNOT be reused for another batch.
- Once vegetables are heated or soaked, pH changes
- Produce absorbs brine
- Pickling brine becomes less acidic
If the vegetables were raw packed into jars, then the pickling brine was added, it CAN be reused for another batch.
