Apple cider vinegar (ACV) is a popular natural remedy and ingredient in many recipes. However, like any other food product, it can go bad if not stored properly or if it’s past its expiration date. In this article, we’ll explore the signs of spoilage, the shelf life of apple cider vinegar, and how to store it to maintain its quality.
Understanding Apple Cider Vinegar
Before we dive into the signs of spoilage, let’s understand what apple cider vinegar is and how it’s made. Apple cider vinegar is a type of vinegar made from fermented apple cider. The fermentation process involves converting the sugars in the apple cider into acetic acid, which gives the vinegar its characteristic sour taste and aroma.
Apple cider vinegar is a natural product that contains a variety of compounds, including acetic acid, antioxidants, and polyphenols. These compounds are responsible for its potential health benefits, such as reducing inflammation, improving digestion, and boosting the immune system.
Signs of Spoilage
Apple cider vinegar can go bad if it’s not stored properly or if it’s past its expiration date. Here are some signs of spoilage to look out for:
Off Smell
One of the most obvious signs of spoilage is an off smell. Apple cider vinegar should have a sour, tangy aroma. If it smells strongly of ammonia, bleach, or has a sour smell that’s overpowering, it may have gone bad.
Slime or Mold
Check the surface of the vinegar for any signs of slime or mold. If you notice any visible growth, it’s best to err on the side of caution and discard the vinegar.
Cloudy or Murky Appearance
Apple cider vinegar should be clear or slightly cloudy. If it’s become cloudy or murky, it may be a sign of spoilage.
Sediment at the Bottom
Some apple cider vinegars may have a small amount of sediment at the bottom of the bottle. However, if the sediment is excessive or has a strange texture, it may be a sign of spoilage.
Taste
If you’re unsure whether the vinegar has gone bad, try tasting it. If it tastes sour or bitter, it’s likely still good. However, if it tastes strongly of ammonia or has a strange, unpleasant flavor, it may have gone bad.
Shelf Life of Apple Cider Vinegar
The shelf life of apple cider vinegar depends on several factors, including the storage conditions, the quality of the vinegar, and the packaging.
Unopened Apple Cider Vinegar
Unopened apple cider vinegar can last for several years if stored properly. The shelf life of unopened apple cider vinegar is typically:
- 2-3 years at room temperature (68-72°F/20-22°C)
- 5-7 years in the refrigerator (39-41°F/4-5°C)
- 10-15 years in the freezer (-18°C/0°F)
Opened Apple Cider Vinegar
Once opened, apple cider vinegar can last for several months to a year, depending on the storage conditions. The shelf life of opened apple cider vinegar is typically:
- 6-12 months at room temperature (68-72°F/20-22°C)
- 1-2 years in the refrigerator (39-41°F/4-5°C)
How to Store Apple Cider Vinegar
To maintain the quality and shelf life of apple cider vinegar, it’s essential to store it properly. Here are some tips:
Store in a Cool, Dark Place
Apple cider vinegar should be stored in a cool, dark place, such as a pantry or cupboard. Avoid storing it near direct sunlight, heat sources, or moisture.
Use a Tight-Fitting Lid
Make sure the lid is tightly sealed to prevent air from entering the bottle. This will help prevent spoilage and contamination.
Keep it Away from Strong-Smelling Foods
Apple cider vinegar can absorb odors from nearby foods, so it’s best to store it away from strong-smelling foods like onions, garlic, and fish.
Refrigerate After Opening
Once opened, it’s best to refrigerate apple cider vinegar to slow down the fermentation process and prevent spoilage.

What are the signs that apple cider vinegar has gone bad?
Apple cider vinegar can go bad if it is not stored properly or if it has been contaminated. Some common signs that apple cider vinegar has gone bad include an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to err on the side of caution and discard the vinegar. Additionally, if the vinegar has been exposed to heat, light, or oxygen for an extended period, it may have degraded in quality and lost its potency.
Another sign that apple cider vinegar has gone bad is a change in its color or clarity. Fresh apple cider vinegar is typically a clear, amber-colored liquid. If it has become cloudy or developed an unusual color, it may be a sign that the vinegar has gone bad. However, it’s worth noting that some types of apple cider vinegar, such as those with a mother of vinegar, may naturally have a cloudy appearance. In this case, it’s best to check the vinegar’s smell and texture to determine if it has gone bad.
How long does apple cider vinegar typically last?
Apple cider vinegar is a fermented product that can last for a long time if stored properly. Generally, apple cider vinegar can last for up to 5 years if it is stored in a cool, dark place, such as a pantry or cupboard. However, the shelf life of apple cider vinegar can vary depending on factors such as the acidity level, storage conditions, and handling practices. If you store apple cider vinegar in the refrigerator, it can last even longer, typically up to 10 years or more.
It’s worth noting that apple cider vinegar is a self-preserving product, meaning that it has natural antimicrobial properties that can help prevent spoilage. However, this does not mean that it is invincible to contamination or degradation. To ensure the longest shelf life, it’s best to store apple cider vinegar in a clean, airtight container and keep it away from heat, light, and moisture.
Can I still use apple cider vinegar if it has gone bad?

Label the container with the date and contents, and then store it in the freezer at 0°F (-18°C) or below. When you’re ready to use the vinegar, simply thaw it in the refrigerator or at room temperature. Note that frozen apple cider vinegar is best used within 6-12 months for optimal quality and potency.
Is it safe to consume apple cider vinegar that has been contaminated with mold?
No, it’s not safe to consume apple cider vinegar that has been contaminated with mold. Mold can produce toxins that can cause illness, and consuming contaminated vinegar can lead to health problems. If you notice any mold growth on the surface of the vinegar or in the container, it’s best to discard it immediately.
However, if you’re unsure whether the mold is harmless or not, it’s always best to err on the side of caution. Check the vinegar’s smell and texture to determine if it has gone bad. If it has an off smell or slimy texture, it’s likely that the mold has contaminated the vinegar and it’s not safe to consume. In this case, it’s best to discard the vinegar and purchase a fresh bottle.
Can I make my own apple cider vinegar at home to ensure its quality and potency?
Yes, you can make your own apple cider vinegar at home to ensure its quality and potency.
