Rice vinegar is milder than most vinegars, but it still has enough acidity to be self-preserving. Treat it the same way you treat your other vinegars: sealed, cool, dark. It will last for years.
How to Store Rice Vinegar
Store in a cool, dark place with the cap tightly sealed. Refrigeration is not necessary. Like all vinegars, the acidity preserves it indefinitely. Seasoned rice vinegar (with added sugar and salt) has the same shelf life as plain.
How to Tell if Rice Vinegar Has Gone Bad
Look for these signs that rice vinegar has spoiled: rice vinegar does not truly spoil. cloudiness or sediment is normal. the flavor may become slightly stronger over time.
The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.

Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been.
