Does raw organic apple cider vinegar need refrigeration?

Here's why:

* Naturally Preservative: Apple cider vinegar is naturally acidic, with a pH level of around 2.5-3.5. This acidity inhibits the growth of most bacteria and molds, acting as a natural preservative.

* Unpasteurized: Raw, unfiltered apple cider vinegar is not pasteurized, meaning it hasn't been heated to kill bacteria. This is why it contains beneficial bacteria and enzymes, known as "the mother."

* Low Water Activity: The high acidity and low water activity in raw apple cider vinegar create an environment unfavorable for microbial growth.

However, there are a couple of things to keep in mind:

* Storage: While refrigeration isn't strictly necessary, it can help prolong the shelf life and preserve the beneficial bacteria.

* Exposure to Heat: Prolonged exposure to high temperatures can degrade the quality of the vinegar and affect its flavor and aroma. It's best to store it in a cool, dark place.

In general, raw, unfiltered apple cider vinegar will last for a long time at room temperature, but storing it in the refrigerator can extend its shelf life even further.
