White vinegar is not used that frequently in cooking; therefore, people always find their long-stored bottles in the pantry.
Once they find these bottles, they get confused about whether they should use them or do white vinegar go bad.
No matter how long you have stored the bottle, it will look fine but be sure not to use it immediately.
That is because prolonged storage makes the white vinegar prone to bacteria and contamination.
Therefore you must check the vinegar before adding it to your recipe to avoid any damage.
White Vinegar Shelf Life Explained
The shelf life of white vinegar is quite long because of its acidic nature - the same acidic protection helps explain balsamic vinegar shelf life guide.
This helps the vinegar to avoid bacteria, fungi, and other contaminations.
You can keep white vinegar even for an extended period; the only difference is that one can feel its taste.
The quality and taste of the vinegar will degrade over time, but this does not mean that it will not go bad.
When vinegar comes in contact with external factors, it deteriorates faster than before.
Thus the only way to keep your vinegar safe and preserve its quality is to keep it safe from external factors.
You have seen that store-bought vinegar bottles come with a best-by date, but these are not expiry dates.
These dates indicate the period until the vinegar gives a strong taste and its quality is top-notch.
However, after that, the process of oxidation increases its pace, and the vinegar declines in quality.
The vinegar is expected to last more until the bottle is unopened because it's entirely sealed.
However, when the bottle is opened, then you will not be able to preserve the flavor of the vinegar as long as air and moisture will make it bad in a short span.
How to Tell if White Vinegar Has Gone Bad?
- Foul Smell
One cannot tell if vinegar is bad as the signs are not that clear, and you need a close examination for that.
One thing you can notice is the smell of the vinegar because the smell becomes sour or unusual if it has gone bad - the same sniff test applies to red wine vinegar spoilage signs and storage.
So you just need to sniff the vinegar, and you will know whether it still contains that quality.
- Discoloration
Another noticeable change that you can find is a color change.
If you find that the color of the vinegar is not similar, then before then, it has been contaminated; you should discard it.
If you keep storing the bottle for a more extended period, the color will begin to turn a little yellow, so if the color of old found vinegar contains a yellow shade, you should discard it.
- Take a Sip
If you have examined the vinegar's color and smell and it's not different from before, you can taste it.
Use a tablespoon and take a sip of vinegar to see if there is any difference in taste.
Because of the extended storage, the vinegar will not be that strong, and its taste will change.
How to Store White Vinegar?
- Store in a Cool and Dry Place
When storing white vinegar, be sure the place you select is cool and dry.
That is because water or any other liquid causes moisture and will make the vinegar go bad.
Thus it will be good to store the vinegar in a cool and dry place, like a kitchen cupboard.
- Seal the Bottle Tightly
The store-bought vinegar can be stored for an extended period because it is adequately sealed.
But once the lid of the bottle is opened, it gets a lot of exposure to air and moisture.
Therefore you should seal the bottle correctly or transfer it to an airtight container if the original bottle is not sealed properly.
- Avoid Storage in Heat
White vinegar is acidic; thus, it must not be kept in heat or direct sunlight.
Although it can be stored at room temperature easily by heat, excess heat makes it contaminated.
Therefore, you should not place it near the stove or a place in the pantry that is prone to sunlight.
