Well, storing rice vinegar is fairly easy. Unopened bottles can be stored at room temperature without worry it might affect the quality.

Make sure to choose a place away from a window or any sources of heat like air vents or radiators. The pantry works best, but kitchen cabinets work as well – just choose one away from the stove.

Once you open the bottle, you should follow the manufacturer’s instructions. Some state that the rice vinegar is fine at room temperature, but some say it should be left in the fridge.

Either way, follow the manufacturer’s recommendation for the best results. If you damaged the label and can’t check it anymore, just store it in the fridge after opening.

    • Transfer the liquid into a freezer-safe, airtight container
    • Leave overnight in the fridge to thaw.

The Shelf Life Of Rice Vinegar

Lpc Does Rice Vinegar Go Bad

Rice vinegar can go bad in specific situations, we have already concluded. Even the quality can be affected after a while. How long is that while?

To be fair, rice vinegar comes with a best-by or a best-before date printed on the label. What does that mean?

The best-by date is a manufacturer’s guarantee that the product in question will retain the same quality up to that date. After the specified date passes, the product will probably not go bad.

To be honest, the quality usually remains the same for quite some time, provided that the food item is stored correctly. The best-by should simply be taken as an estimate.

Rice vinegar will stay safe for around five years past the production date. That’s around three years past the best-by date if kept at room temperature.

How To Check If The Rice Vinegar Has Gone Bad

Unfortunately, rice vinegar can go bad, and it will usually go bad at the worst possible moment. On the other hand, proper storage will make sure that it doesn’t go bad anytime soon.

So, the first thing to do to check the wellness of your rice vinegar is to look at the liquid. Because of acidity, vinegar is not likely to grow mold or mildew, but it can happen. Also, any changes in the color are a sign that the vinegar has gone bad.

If you’re not sure about the state, even if the color is fine, a sniff test is a good tell-tale sign your rice vinegar is no longer good. If it smells rotten or just unpleasant, discard it!

The same thing applies if it tastes bad or off. The safest thing to do is throw it out!

However, if you notice that the liquid is cloudy, don’t be alarmed. As long as there are no changes in color, smell, or taste – it’s fine. Cloudiness appears because it’s stored away for a while, nothing else.

Never, under any circumstances, should you use rice vinegar that’s gone bad. Rice vinegar releases peroxides after it’s kept for a long time.

Peroxides are toxic compounds and they can give you food poisoning. Be careful and always check the state of your vinegar before you add it to meals!
