How to Tell if White Wine Vinegar is Spoiled

Because white wine vinegar is highly acidic, it resists spoilage very well. However, there are some signs that can indicate your opened or unopened bottle of white wine vinegar has spoiled:

  • Change in color – Vinegar should maintain a pale, translucent appearance. Yellow, brown, or cloudy discoloration may indicate spoilage.
  • Strange odor – Vinegar normally has a tart, acidic smell. An unpleasant or moldy odor is a red flag for spoilage.
  • Texture changes – Spoiled vinegar may become slimy or develop a strange texture.
  • Mold – The growth of mold, yeast, or bacteria colonies signals spoiled vinegar.
  • Strange taste – Vinegar should taste tart and acidic. A bitter, unpleasant, or very weak taste could mean spoilage.

If your white wine vinegar exhibits any of these characteristics, it is best to discard it.

Is Expired White Wine Vinegar Safe to Consume?

In most cases, white wine vinegar is still safe to consume even after its expiration date, provided it has been stored properly and shows no signs of spoilage. Here are a few factors to consider:

  • Acidity level – The acidity of vinegar prevents microbial growth and spoilage. As long as the acidity level remains stable, vinegar has a long shelf life.
  • Storage conditions – Unopened bottles of vinegar stored in a cool, dry place are likely still good after expiration. Vinegar stored in hot, humid conditions is more prone to spoilage.
  • Container seal – If the bottle or container seal is intact and has not been opened, the product inside has extra protection from spoilage.
  • Sensory evaluation – Look, smell and taste the vinegar. If nothing seems off, it is likely still good to consume.

The FDA advises that unopened, commercially bottled vinegars can be used 1 to 2 years after the expiration date, if stored properly. Once opened, vinegars have a shorter shelf life of 6 months to a year.

Uses for Expired White Wine Vinegar

As long as expired white wine vinegar shows no signs of spoilage, it can be safely used for many cleaning and cooking purposes, including:


  • Natural all-purpose cleaner – Mix 1 part vinegar to 1 part water and use for cleaning countertops, floors, windows, mirrors, appliances and more.
  • Removing soap scum and hard water stains – Apply white wine vinegar directly and scrub.
  • Disinfecting surfaces – Wipe down surfaces with undiluted white wine vinegar to kill bacteria.
  • Descaling kettles or coffee machines – Boil equal parts vinegar and water to remove mineral deposits.
  • Unclogging drains – Pour 1/2 cup baking soda down the drain followed by 1/2 cup vinegar. Cover and let fizz for 30 minutes before rinsing with hot water.


  • Vinaigrettes and salad dressings
  • Marinades for meat, fish and vegetables
  • Deglazing pans to make sauces
  • Pickling fruits and vegetables
  • Poaching eggs

Because it is acidic, vinegar brings brightness and balances flavors in many dishes without compromising food safety.

Other Uses

  • Natural fabric softener – Add 1/2 cup to laundry rinse cycle.
  • Glass cleaner – Mix equal parts white wine vinegar and water in a spray bottle.
  • Pet odor remover – Lightly spray on carpets and pet beds and let sit for several minutes before blotting.
  • Weed killer – Spray undiluted vinegar on unwanted weeds.

How Long Does Unopened White Wine Vinegar Last After Expiration?

Unopened white wine vinegar has a shelf life of 1 to 2 years past its printed expiration date if it is stored properly, according to the FDA and other food safety sources. To maximize shelf life:

  • Store vinegar in a cool, dark pantry or cupboard away from direct sunlight and sources of heat.
  • Keep the bottle or container tightly sealed.
  • Refrigerate vinegar after opening to extend its shelf life.
  • Keep vinegar in its original container if possible.
  • Discard vinegar that develops any signs of spoilage like changes in color, texture or odor.

With proper storage, unopened white wine vinegar can maintain quality and remain safe for use for up to 2 years after the printed expiration date. However, it is always best to evaluate the product visually and by smell before use after this time period.

Can I Use Expired White Wine Vinegar for Cooking?

Yes, you can safely use white wine vinegar that has passed its expiration date for cooking, as long as it shows no obvious signs of spoilage. Its highly acidic nature prevents foodborne pathogens from growing.

Here are some common uses for expired white wine vinegar in recipes:

Vinaigrettes and Salad Dressings

The acidic tang of vinegar brightens up salad dressings. Combine expired white wine vinegar with oil, herbs, shallots, garlic and other ingredients for flavorful vinaigrettes.


The acid in vinegar tenderizes meats and infuses flavor. Use expired white wine vinegar to marinate chicken, beef, fish and vegetables before grilling or roasting.


Preserve fruits and vegetables with an acidic white wine vinegar brine. Pickled foods keep for months in the fridge.


Deglaze a pan with white wine vinegar after cooking meat or vegetables. Scrape up browned bits and reduce to make a flavorful pan sauce.


Add white wine vinegar to poaching liquid for delicate foods like eggs or fish. This helps coagulate the proteins for light, silky textures.

As long as it has been properly stored and shows no discoloration, strange smells or texture changes, expired white wine vinegar can be substituted in any recipe calling for vinegar without sacrificing safety or quality.

Should I Taste Expired White Wine Vinegar Before Using?

It is advisable to taste a small amount of expired white wine vinegar before using it in recipes or for cleaning purposes. A quick taste test can confirm if the vinegar has maintained its expected tart, acidic flavor or if any off-flavors have developed.

When tasting old vinegar, look out for the following:

  • Tart, acidic flavor – Properly stored white wine vinegar should still taste bright and acidic even when expired.
  • Bitter flavors – A bitter taste could indicate spoilage or the development of compounds like acetic acid over time.
  • Muted, weak acidity – Vinegar that is flat or seems diluted may have lost some of its acidic power.
  • Moldy or strange aftertaste – An unusual flavor could signal microbial growth or interaction with the container.

If the vinegar passes the taste test with no off flavors, it should be fine for cleaning or cooking. However, if you notice anything unappealing during tasting, it is best to discard the vinegar.

Does White Wine Vinegar Go Bad?

Yes, white wine vinegar can eventually go bad if stored improperly for a very long time. Signs of spoiled vinegar include:

  • Cloudiness or sediment
  • Mold growth
  • Strange colors or textures
  • Unpleasant odors
  • Loss of acidity
  • Flat or rancid taste

While vinegar has an extended shelf life due to its acidity, extreme age or poor storage conditions can allow contamination and spoilage by bacteria, yeasts, and molds. Exposed oxygen can also cause vinegar to lose its acidic bite over many years.

Properly stored, unopened white wine vinegar may remain good 1-2 years past its printed expiration date. Opened bottles have a shorter shelf life of about 1 year. Any vinegar showing signs of spoilage should be discarded.

How to Store White Wine Vinegar

To maximize freshness and shelf life of white wine vinegar, follow these storage tips:

  • Store vinegar in a cool, dark place like a pantry or cupboard away from heat and sunlight.
  • Refrigerate opened bottles for up to 1 year of shelf life.
  • Keep vinegar in its original bottle if possible.
  • Seal the container tightly between uses.
  • Check vinegar periodically for any signs of spoilage like cloudiness or odor changes.
  • Use clean utensils to remove vinegar from the bottle to avoid introducing bacteria.

With proper storage, unopened bottles of white wine vinegar can retain quality and safety for more than 2 years past the printed expiration date. This allows you to stock up on vinegar when it is on sale while maintaining optimal freshness.

The Bottom Line

Expired white wine vinegar is likely still safe and effective for cleaning, cooking, and other uses. Its high acidity prevents most microbial growth. Look for changes in appearance, texture, aroma or taste to determine if vinegar has spoiled over time. With proper storage, white wine vinegar can be safely used well past its expiration date within 1-2 years if sealed and up to 1 year if opened.
