If you love cooking Asian food, like we do, you probably have a bottle of rice vinegar that has been sitting in your cupboard for a while.

But does rice vinegar go bad?

Rice vinegar doesn’t go bad in the traditional sense (in theory), but most brands advise using it within two years for it to be at its best.

Vinegar is an ingredient that is commonly used to preserve other ingredients. This is why it has such a long shelf life.

However, it’s essential to know when it is past its expiration date if you want it to be fresh and flavorful.

In this article, we are going to tell you everything you need to know about rice vinegar and exactly how to store it, so it stays fresh for as long as possible.

If you’re ready to learn more, let’s get to it.

What Exactly is Rice Vinegar, and What is it Made of?

Rice vinegar, or rice wine vinegar, is a popular seasoning used in many Asian Cuisines.[*]

It is sweet but citrusy with a hint of rice wine flavor. It is most often used in stir-fries, dressings, sushi, and sauces. 

Its ingredients, like with most vinegar, are pretty simple.

It is made from [*]:

1. Fermented Rice

Rice is the base ingredient that sets this vinegar apart from the others.

It is fermented using the second ingredient:

2. Acetic Acid

Acetic acid ferments the rice to create this vinegar.

It also gives the vinegar its signature zing. Acetic acid is the same acid that you find in other varieties of vinegar like white spirit and balsamic.

3. Rice Wine

Rice wine is added in small quantities to help convert the sugars into alcohol and from there in acetic acid. It also gives the vinegar a hint of sweetness.

4. Water

This simply forms the body of the vinegar to dilute it to a consumable level.

Does Rice Vinegar Go Bad?

Rice vinegar doesn’t go bad in the traditional sense, but will lose its potency after its indicated expiration date.

If you happen to have a bottle on your shelf that you are wondering about, there are a few things to look out for:

Fresh rice vinegar will be:

1. Fresh in Flavor

It has a sweet but very tangy flavor with a hint of the rice wine used to make it.

When it is fresh, a little goes a long way because this vinegar is so potent.

2. Clear, Bright Color

Fresh one will be clear to slightly pale yellow in color.

You can maintain this color by storing away from harsh sunlight.

How Do You Know If Rice Vinegar is Bad

Once it’s gone past its expiration date, rice vinegar will not have the same potency or color.

It will not go off or mold in the way other products might but it will show signs of age in other ways.

There are a few ways you can tell that your vinegar is past its best:

 1. Loss of Flavor

Rice vinegar past its expiration date will have a less potent flavor.

It will not taste bad, but won’t have the same zingy sweetness you would expect. 

This will affect the flavor of whatever you are cooking and possibly throw it out of balance.

2. Discoloration

Over time, the pale yellow color of the vinegar may darken.

This may indicate that it is past its best, but it won’t be dangerous to use. 

How Long Does Rice Vinegar Last?

Rice vinegar has an average shelf life of two years. [*]

It may be hard to tell whether it has gone off or not but that’s where the expiration date comes in.

The expiration date doesn’t indicate that the vinegar is off but instead that its acidity levels will have decreased. After this expiration date, the flavor will be compromised.

How To Store Rice Vinegar?

We suggest storing rice vinegar at room temperature in a cupboard.

Storing vinegar in the fridge will not harm it, but it will take up unnecessary space in your fridge.

Here is a step by step guide on how to best store rice vinegar:

Step 1: Keep it in its original bottle

Most rice vinegars come in a well-sealed glass bottle, so it is best to keep them in the original packaging.

However, if you buy it in bulk, it may come in a plastic bottle. If this happens we recommend transferring it to a clean, sealable glass jar.

Step 2: Place in a dark cupboard

It is important to keep your vinegar away from sunlight or heat.

This may cause the vinegar to lose its flavor more quickly. 

A dark cupboard or pantry will keep it away from light and keep it at a steady temperature.

Step 3: Always close the cap tight

Contaminants are one that can cause rice vinegar to go bad.

To prevent anything from getting into it, make sure you close the lid tightly every time you use it.



So now that you have been thoroughly immersed in rice vinegar, what can we take away from this?

  • Rice vinegar has a shelf life of 2 years.
  • It can be stored at room temperature in a dark cupboard
  • Eating bad rice vinegar will not make you sick

Rice vinegar is a pantry staple that, we think, all good home cooks should have in their kitchens. We hope this article has been helpful and motivated you to stock up on some zingy rice vinegar.
