How Long Does Vinegar Last?
Vinegar keeps indefinitely in the pantry, opened or unopened, and does not need refrigeration. Cider, wine, rice and balsamic vinegars taste best within about 2–3 years of opening; white vinegar does not change.

Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Vinegar is a dilute solution of acetic acid produced by fermenting alcohol, and it is acidic enough to preserve itself. Distilled white vinegar is essentially unchanged for decades. Wine, cider, rice and balsamic vinegars stay safe just as long, but they may turn cloudy, throw sediment, or grow a harmless jelly-like vinegar mother, and their flavor can slowly fade.
How to store vinegar
- Keep the cap tight. Vinegar does not spoil, but with air exposure it slowly loses acidity and aroma and is more likely to form a mother.
- Store it in a cool, dark cupboard in glass or the original plastic bottle. Never keep vinegar in metal containers, which it will corrode.
- Strain out a vinegar mother through a coffee filter if it bothers you; the vinegar underneath is fine to use.
- For home canning and pickling, use commercial vinegar labeled 5% acidity, not homemade vinegar or a very old opened bottle of uncertain strength.
- Refrigerate homemade infused vinegars made with fresh herbs, garlic or fruit and use them within a few months.
How to tell if vinegar has gone bad
- Vinegar essentially does not spoil. A slimy, jelly-like disc or strands in the bottle is vinegar mother, which is harmless cellulose and bacteria.
- Cloudiness or sediment in cider, wine or balsamic vinegar is a cosmetic change and not a safety concern.
- A weak, flat taste with little sharpness means the acidity has dropped; fine for dressings, but do not rely on it for pickling.
- Visible mold in a flavored vinegar containing fruit, herbs or garlic. Discard that bottle.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

| State | Fridge | Freezer | Pantry |
|---|---|---|---|
| Opened | Not recommended | Not recommended | Indefinitely |
| Refrigerating or freezing is harmless but pointless. Flavored vinegars with fruit or herbs are best within 6 months. | |||

Not safe = perishable: no more than 2 hours at room temperature (1 hour above 90°F / 32°C). Not recommended = possible, but quality suffers or it serves no purpose.
Frequently asked questions
Does vinegar go bad?
No, not in any way that affects safety. Vinegar's acidity prevents harmful microbes from growing, so it keeps indefinitely without refrigeration. Distilled white vinegar is practically unchanging. Other vinegars may become cloudy, develop sediment or lose some flavor over the years, which are changes in appearance and taste only.
What is the slimy blob floating in my vinegar?
It is a vinegar mother, a mat of cellulose and harmless acetic acid bacteria. It forms most often in unpasteurized or opened cider and wine vinegars. It is safe. You can strain it out and keep using the vinegar, or leave it, or use it to start a batch of homemade vinegar.
Does apple cider vinegar need to be refrigerated?
No. Apple cider vinegar, including raw unfiltered types sold "with the mother," is self-preserving and belongs in the pantry. Refrigeration does not extend its safety. Keep it capped and out of sunlight, and expect more cloudiness and sediment over time in unfiltered vinegar.
Can I use vinegar after its expiration date?
Yes. The date on vinegar is a best-by date for peak flavor and color, not a safety limit. White vinegar can be used for cooking and cleaning indefinitely. For canning and pickling, where acidity matters for safety, use a reasonably fresh bottle labeled 5% acidity.
Does balsamic vinegar go bad?
Balsamic vinegar does not become unsafe, but supermarket balsamic is at its best within about 3 years of opening. After that it may taste flatter or form sediment. Balsamic glazes and creams are different: they contain added sugar and thickeners, so follow the label, which usually gives a much shorter period.
