Apple Cider Vinegar

The reason why apple cider vinegar does not require refrigeration is due to its high acidity level, which acts as a natural preservative. This means that even if you leave your bottle of apple cider vinegar out on the kitchen counter for an extended period of time, it will remain safe to consume.
Additionally, refrigerating apple cider vinegar can cause it to become cloudy or develop sediment at the bottom, but this doesn’t affect its quality or potency. In fact, some experts argue that storing apple cider vinegar in the refrigerator may even diminish its health benefits.
