Does red wine vinegar need to be refrigerated?

Red wine vinegar does not necessarily need to be refrigerated after opening, as its high acidity level acts as a natural preservative. Keeping it in a cool, dark place such as a pantry or kitchen cabinet is generally sufficient to maintain its quality. However, if you live in a particularly hot or humid climate, refrigeration can help prolong its freshness and flavor.

Here are some additional tips for storing red wine vinegar:

- Always keep the vinegar in its original bottle or a clean, airtight container to prevent contamination and preserve its flavor.

- Avoid exposing the vinegar to direct sunlight, as this can affect its taste and quality over time.

- If you notice any changes in the appearance, smell, or taste of the vinegar, discard it for safety reasons.
