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.

Rice vinegar 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.

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 rice 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.

What is the Best Way 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.
