Does Vinegar Go Bad? (2023)

FAQs

Does Vinegar Go Bad? ›

Vinegar does not expire. Consuming "old" vinegar will not harm you, the way other old food items might, but the flavor and quality will certainly change over extended periods of time. Though there's no expiration, there is a sort of "sweet spot" for vinegar storage, and it varies by the type.

Contrary to “when in doubt, toss it out,” there is no need to toss out older vinegars. They are safe to use but may change over time. If the change is too bothersome for food preparation, vinegar past its prime can still be used for cleaning, weed control, fabric softening, and dying to name a few.

According to The Vinegar Institute, “vinegar's shelf life is almost indefinite” and due to the high acidity of the product, it is also “self-preserving and does not need refrigeration.” Phew. This infinite shelf life applies to unopened and opened bottles of vinegar of all kinds.

Can any bacteria live in vinegar? Yes, they can, but would need anaerobic conditions. Many anaerobic bacteria, like Clostridia, can growth using acetic acid (the mean component in vinegar) as carbon and energy source. Acetate is reduced to formic acid or ethanol depending pH, and releasing hydrogen.

The only real side effect from leaving vinegar to its own devices is that its acidity will gradually decrease over time, making it less potent. This is why a "best by" date can be found on the bottle, but it's still perfectly fine long past that — it isn't an "expiration date," by any means. Vinegar does not expire.

If you're noticing a general cloudiness in your vinegar, that's your signal to buy a new bottle. “When the vinegar starts getting cloudy, or the flavor is off, then oxidation has significantly changed the quality of the product,” explains Regusci. “But I wouldn't say spoiled, I would say low-quality.”

Once opened and exposed to air, however, harmless “vinegar bacteria” may start to grow. This bacteria causes the formation of a cloudy sediment that is nothing more than harmless cellulose, a complex carbohydrate that does not affect the quality of the vinegar or its flavor.

So how long is vinegar good after the expiration date? Surprisingly, the answer is indefinitely. In terms of how long vinegar can safely be used to cook and clean with, it truly will never go bad.

In addition to cloudiness or sediment, vinegar may develop a slimy substance called a “mother,” which may look and sound scary but is actually harmless. As its name suggests, the mother can even be used to make a new batch of vinegar. So, we can keep those bottles of vinegar in the pantry for another year, or longer.

Can you eat mother of vinegar? ›

What: Slimy strings and globs at the bottom of a jar of vinegar. What it is: They may look gross, but these little blobs of goop are what's known as “mother of vinegar”—essentially, they're clumps of the bacteria and yeast combo that turns alcohol into vinegar. Eat or toss? Eat!

And if you get my drift, acetaldehyde in concentration smells a lot like acetone. So the acetone smell is what happens when the reaction to make vinegar isn't completely finished. Many bacteria just make acetaldehyde and then start creating the pungent odor.

White vinegar is made by fermenting sugar cane extract or by combining acetic acid with water. Whilst distilled vinegar can be made from any type of vinegar, with more ethanol separated from the base mixture. You can use both types in tasks like cleaning, cooking, medical and laboratory tasks.

What is floating in my apple cider vinegar? ›

“It's a little bit of sediment from the apples themselves, and it's also vinegar mother,” which is a natural by-product of the fermentation process. “The vinegar mother grows over time, and that's usually the swirly stuff that people see at the bottom of the bottle.”

A thick, gelatinous layer is formed by the acetic acid bacteria on the surface of the vinegar. This layer is known as 'The Mother' because it is the catalyst that gives rise to the vinegar.

A vinegar mother is a gelatinous disc that looks like a slice of wobbly raw liver. It's composed of a form of cellulose and acetic acid bacteria (mycoderma aceti) that develops on fermenting alcoholic liquids, and turns alcohol into acetic acid with a little help from some oxygen in the air.

Is Vinegar More Effective Than Bleach? Vinegar truly is better than cleaning with bleach when it comes to killing mold. The EPA does not recommend using bleach to kill or remove mold, except in special circumstances. In most cases, “a background level of mold spores will remain” after the application of bleach.

Bleach kills virtually every species of indoor mold that it comes into contact with including mold spores which leaves a sanitized surface making it resistant to future mold growth.

Yes, ammonia is a strong mold killer. In fact, many commercial mold cleaning products contain ammonia. It's stronger than vinegar and is similar to bleach in terms of potency, although make sure to never mix two together — ammonia and bleach react to produce toxic fumes.

Apple cider vinegar is simply a vinegar made from apple juice or apple cider. It comes in two versions: filtered and unfiltered. The difference between the two is the “mother,” which is a somewhat murky collection of cellulose and acetic acid bacteria that's removed when the vinegar is filtered.
