Rice vinegar is a popular ingredient in Asian cuisine. It enhances the flavor of dishes by adding a mildly sweet and sour flavor.
Most times, rice vinegar is used in sushi rice and dressings. It is also used as a sweetener in various dishes.
Most people in the United States do not use rice vinegar as often as other vinegar varieties. Therefore, it is one of those ingredients that tend to last for a long time.
If you bought a bottle of rice vinegar months or years ago and are unsure whether it is still safe to consume since you had stored it in your pantry, you may be wondering; do you have to refrigerate rice vinegar?
The simple answer is that you do not have to refrigerate rice vinegar. Naturally, rice vinegar has high acidity levels.
Therefore, it can last for several years, even when you store it in the pantry. However, its quality may start to deteriorate after a few years, so you may be forced to discard it.
This article will discuss everything you need to know about rice vinegar, including its shelf life, proper storage, and signs of spoilage.
What is it?

Rice vinegar is a product of fermented rice water. During the fermentation process, sugars in the rice are first converted to alcohol, then to vinegar.
Although rice vinegar is acidic, it has a somewhat sweet flavor. Compared to white vinegar, it is quite mild.
Therefore, it is a good addition to salad dressings, marinades, and several dishes that require a little bit of acidity. You can also use rice vinegar to enhance the flavor of herbs, fruits, and spices.
Rice vinegar has a light color. Therefore, it does not change the color of dishes you add it to. This feature makes it a go-to ingredient in Asian cuisine.
Rice vinegar shelf life.

Rice vinegar has high acidity levels. Therefore, it is naturally not a conducive environment for mold or bacteria growth. Therefore, the shelf life of rice vinegar is very long.
A few people suggest that you can use rice vinegar indefinitely. However, this does not mean that it does not change or go bad.
With time, the quality of rice vinegar starts to deteriorate, and it eventually becomes unpalatable.
If you store rice vinegar properly at room temperature, it will maintain its good quality for up to five years. If you store it in the refrigerator, its quality will remain intact for approximately ten years.

Note that every rice vinegar bottle has a best by date. The best by date does not necessarily mean the rice vinegar is no longer safe to use.
You can use it several months past the best by date as long as its quality is good and there are no signs of spoilage.
Generally speaking, rice vinegar does not have an exact shelf life. The dates we have discussed above are simply estimates of how long it will retain its good quality.

How to properly store rice vinegar.

For rice vinegar to maintain its good quality for a long time, you must store it properly.
It would be best if you stored rice vinegar the same way you store other vinegar varieties. Place the bottle in a dark and cool place. Additionally, you should ensure that it is far away from any sources of heat or light.
I highly recommend storing rice vinegar in your pantry. If you don’t have one, you can always store it in your kitchen cabinet.

You must seal the bottle tightly after every use since its quality will deteriorate faster if you frequently expose it to air.
Sealing the bottle tightly will ensure its quality remains intact.
Once you open the bottle of rice vinegar, you should follow the manufacturer’s storage recommendations.
Some suggest you refrigerate it, and others suggest you store it at room temperature. Generally, rice vinegar is a shelf-stable product. That means that you can safely store it at room temperature.

If the rice vinegar bottle label does not suggest that you refrigerate once you open the bottle, you can safely store it in your pantry or kitchen cabinet.
However, if you are sure you won’t use the rice vinegar within five years, store it in the refrigerator to extend its shelf life.

Does rice vinegar go bad?

A recent study by the Vinegar Institute revealed that the shelf life of rice vinegar is almost indefinite.
The reason for this is that rice vinegar is highly acidic; hence it is self-preserving.
Despite this, rice vinegar can go bad when stored for an extended period. You will notice certain changes that indicate the vinegar may no longer be safe to use.
Read on to see the various signs that your rice vinegar has gone bad.
Signs that your rice vinegar has gone bad.

As discussed above, the shelf life of rice vinegar extends way past its best by date. You can safely use it weeks past the best by date.
However, you must ensure that the rice vinegar is still of good quality before using it in your dishes.
Here are a few signs that your rice vinegar is no longer safe to use.
- Color change
If you notice a color change in your rice vinegar, the chances are that the quality of the vinegar has started to deteriorate. I suggest you discard it.
- Weird smell

Naturally, rice vinegar has a sharp smell. However, it should not have an off or rotten smell. If your vinegar smells rotten, it may no longer be safe to use.
- Change in flavor
If there is no change in color or smell, but you still aren’t sure whether the rice vinegar has gone bad, taste it.
If the taste is somewhat bitter or it just doesn’t taste good, the chances are that it is no longer safe to use, and you should discard it.
Note that the quality of rice vinegar deteriorates with time, and it becomes less palatable.

Conclusion
Unless your manufacturer specifically suggests that you refrigerate rice vinegar, you do not have to.
You can safely store rice vinegar in your pantry since it is a self-preserving product.
