Can Vinegar Go Bad?
Vinegar cannot go bad as it is self-preserving because of its acidic nature and can last indefinitely without refrigeration. However, if kept for a very long time, its quality, freshness, and texture may suffer but there will be no effect on the taste and the vinegar remains harmless.
As already mentioned, vinegar does not spoil, but it can lose some of its qualities over the years, especially if it has not been stored properly. While nothing happens in the normal sense of the word, most types of vinegar lose quality over time.
Because of this, the vinegar itself does not spoil, and it can be used without harm to oneself. Plus, vinegar doesn’t need to be refrigerated, so you can store it in your pantry or closet without worrying about it going bad.

It’s very unlikely that balsamic vinegar has gone bad enough to hurt you (unless it’s been stored incorrectly, but you’ll definitely know it’s a bad dressing). Commercially produced balsamic vinegar has a best-before date but still has a relatively long shelf life if stored properly.
The typical shelf life is over 20 years, but the truth is that with proper storage, you can use traditional balsamic vinegar for longer. You might be surprised to learn that balsamic vinegar dressing can retain its best quality for up to three years when stored properly, but even after that period, it can be used indefinitely.
Stored properly, apple cider vinegar will usually keep its best qualities for about two years, although it can be used safely almost indefinitely. Red wine vinegar retains its best quality for about two years after opening but can be used safely indefinitely.
Can vinegar be used after the expiration date?
Vinegar has an indefinite shelf life and can be safely used for eating, cooking and cleaning even after the expiration date. The acidity of vinegar means that it is “self-preserving and does not require refrigeration”, and theoretically vinegar has an indefinite shelf life, even after the bottle has been opened.
The acidity of vinegar makes it naturally self-preserving, which is why many bottles of balsamic vinegar improve with age and are sold after ageing. According to the Vinegar Institute, “Due to the acidic nature of vinegar, vinegar is self-preserving and does not need to be refrigerated”.
While balsamic vinegar is at its peak for the first three years (as long as the lid is tight), the bottle can be passed down from generation to generation and is still safe to drink.
How to store vinegar?
As long as you keep the bottle away from light and heat, and keep the lid on, you can be sure your vinegar is fine. As you can see, the best thing you can do for your balsamic vinegar bottle is to store it in a dark place, keep it at room temperature, and cap the bottle tightly. It is best to store vinegar in its original airtight container in a cool place away from heat.
Proper storage of vinegar will help keep it looking its best because it will help reduce evaporation and possible contamination. When vinegar is stored for a long time, its colour may change slightly, and this is normal. Luckily, there are a few steps you can take to keep your vinegar fresh so it stays delicious and retains its natural acidity even past its stated expiration date
| Vinegar | Lasted time |
| Balsamic vinegar | Last for up to 3 years |
| Apple cider vinegar | Last for 2 years |
| Ride wine vinegar | Last for 2 years after opening |
However, if you’re using expired vinegar for cooking, the recipes probably won’t taste as good as they would with fresher ingredients. It’s a good idea to look out for any warning signs that your vinegar may have gone bad (described below). With all the reasons why a bottle of vinegar can be put to good use and enjoyed, there’s also no reason to worry about the vinegar going bad.
As for vinegar spoiling in the sense that it could harm you, the answer is no: drinking expired vinegar is unlikely to result in negative health or safety effects. In fact, vinegar can last indefinitely if you store it properly, preserving its freshness, acidity, and flavour.
Due to the fermentation process that produces vinegar, all varieties have a fairly long shelf life, but the specific shelf life of vinegar depends on the type of vinegar and storage conditions. Malt vinegar also keeps indefinitely, although its quality will begin to deteriorate after two years and may become cloudy.
You can strain the cloudy vinegar to remove some of the sediment and it’s still safe to use, but it won’t taste like a colder bottle. If your bottle of vinegar is already cloudy, dull, or less acidic, even if the vinegar is outdated, you can still use it to clean or add to your fruit and vegetable wash, to control weeds, or to use a cloth.
Do not store vinegar near a dishwasher or stovetop, as constant temperature changes can cause acidity to deteriorate more quickly. Refrigeration can change the taste over time, and moisture added to the refrigerator will cause water to condense inside the bottle, diluting the balsamic.

Vinegar will still be safe to eat for the last three to four years, at least a couple of years, but it won’t taste as good when it comes to taste.
For flavorful vinegar like balsamic, which is a delicious addition to salad dressings, you can track the “open date” on the bottle and replace it after two years, just to ensure the best taste. Manufacturers recommend consuming rice vinegar according to the “use by” date on the bottle to experience the full flavour and quality of the vinegar, but it will likely last up to ten years after that date.
Can you get Sick from Old Vinegar?
Using vinegar after its expiration can lead to unfresh, low quality, and potency. But, whether vinegar goes bad in the sense that it may hurt you is not a question—using expired vinegar leads to any health- or safety-compromising effects.
Can bacteria grow in vinegar?
The bacteriostatic and bactericidal impacts of vinegar were investigated on food-borne pathogenic bacteria, including enterohemorrhagic E. coli. A 0.1 percent quantity of acetic acid in the vinegar reduced the development of all strains tested.
