Vinegar is one substance that has come a long way. It has documented history from different parts of the world and an equally diverse number of variants and preparation styles.

Vinegar is a common ingredient in Asian delicacies, and a visit to any Asian grocery shop will show you just how much variety is available today.

But like with anything else you may wonder, does rice vinegar go bad?
Well, there are instances where it becomes unfit for consumption and detrimental to your health; different reasons cause this.
So, while rice vinegar is beneficial, you need to know how it can be harmful if it gets spoilt, the right ways to store it, and all the signs of “badness” to watch out for.
What is Rice Vinegar anyway?
As long as you are interested in cooking, skin care, or some forms of DIY, then you are familiar with the word “vinegar”.
Originally a French word, it means “sour wine”, and if you have sampled some of it, you can attest to its tart flavor.
This substance is the resulting product when food that contains sugar is fermented to drinkable alcohol, then fermented even further into vinegar.
According to science, vinegar is an aqueous solution which has acetic acid occupying about 5-20% of its total volume.
The acetic acid is a product of the fermentation of sugars, and oxidation of ethanol by acetobacter; a particular bacteria concerned with producing acetic acid. It also contains trace amounts of flavor chemicals.
Rice vinegar, like its name implies, is a product of the systematic fermentation of rice water.
It is a spice used in cooking different meals, from barbecue ribs, salad dressing, and even sushi rice.
How to Store Rice Vinegar Properly?
Rice vinegar is an acidic compound that does not easily support the bacterial or mold growth necessary for decay, and so it has a long shelf life.
But this does not mean that it is immune to rotting. You need to take better care with its storage.
So, unless you intend to use up all your rice vinegar at a go, here are some tips to help you:
- Best place to store unopened or opened containers of rice vinegar is in your pantry.
- If no pantry is available, store in a dry place at room temperature.
- Ensure that you keep your rice vinegar away from direct sunlight and heat.
- Storage of rice vinegar should only be in glass, Stainless Steel, wood, or food-safe plastic. Do not store in metals like brass, copper, aluminium, or iron.
- After opening up a bottle, keep it tightly sealed.
- Refrigerate your rice vinegar once it is close to its expiry date, or if you intend to use it for more than five years.
- Freezing is not necessary, as it waters down the acidic tang after defrosting.
- Also, if freezing, ensure that you make use of a freezer safe container, as the glass can easily shatter at freezing temperatures.
Does Rice Vinegar Go Bad? How Long Does Rice Vinegar Last?
Due to its acidic nature, it is a widespread opinion that rice vinegar does not go bad, but the truth is that with time, it can lose its acidic quality.
It is used as a preservative for several perishable foods, so it has properties that allow it last long even after its best by date.
When not stored correctly, rice vinegar can lose its exciting taste and quality. That happens due to the exposure of vinegar to air, from which it absorbs water.
That, in turn, encourages the growth of acetobacter that further breakdown the acetic acid into water and carbon dioxide; diluting its flavor.
Rice vinegar does not have an exact shelf life, and it has this in common with other types of vinegar, including Cider vinegar.
The dates given by manufacturers as the expiry date is simply an estimate of how long the vinegar would stay fresh.
This date is usually set to two (2) years after its date of manufacture.
Even though rice vinegar is less acidic than most variants, with proper storage, it can last as long as you want.
An unopened bottle of rice vinegar has an expected shelf life of over ten years, while an opened bottle has a shelf life of over five years.
