Should you refrigerate aged white wine vinegar?

Here's why:

* Low pH: Vinegar is naturally acidic with a low pH, making it an inhospitable environment for bacteria growth.

* Age & Fermentation: Aged white wine vinegar has already gone through a long fermentation process, which further reduces the risk of spoilage.

* Preservative: Vinegar contains acetic acid, a natural preservative that inhibits bacteria.

However, there are some exceptions:

* Unpasteurized Vinegar: If your white wine vinegar is unpasteurized, it's best to refrigerate it to ensure freshness.

* Opened Bottle: Once a bottle of vinegar is opened, it's a good idea to refrigerate it to maintain its flavor and quality over time.

In summary: While refrigerating aged white wine vinegar is not strictly necessary, doing so won't hurt and can help extend its shelf life.
