Can apple cider vinegar go bad in the fridge?

In this concise guide, we will answer the query, “can apple cider vinegar go bad in the fridge?” We will also discuss what apple cider vinegar is, if you have to store it in the fridge, and how long apple cider vinegar lasts.

Can apple cider vinegar go bad in the fridge?

No, apple cider vinegar cannot go bad in the fridge.  While store-bought apple cider vinegar has to carry expiration dates (usually a two years period), because the Food and Drug Agency (FDA) requires expiration dates to be stamped on the bottle, apple cider vinegar doesn’t actually expire.

Apple cider vinegar is acidic. A substance’s acidity is measured using the pH scale, which spans from 0 to 14. A pH of less than 7 indicates acidity, whereas a pH of higher than 7 indicates basicity. The major component of apple cider vinegar is acetic acid, which has a strongly acidic pH of 2 to 3.

This acidic nature of apple cider vinegar ensures that it is self-preserving, which implies that it is unlikely to be contaminated with food-spoilage microbes and can resist the process of food spoilage. 

Therefore, you can still consume apple cider vinegar well after its labeled expiration date.

What is apple cider vinegar?

Apple cider vinegar is simply vinegar derived from fermented apple cider. It has a strong acidic taste and is frequently used in marinades, salad dressings, chutneys, and as food preservatives. It’s also excellent for curing veggies.

This multipurpose pantry staple is said to provide a plethora of health advantages, including loss of belly fat, anti-diabetic effects, a natural laxative, blood pressure reduction, antimicrobial effects, cardioprotective effects, as well as decreasing the risk of cancer.

You can make apple cider from crushed apples. It can be left in its raw state (with a murky appearance) or pasteurized and filtered into pure apple juice (with a golden appearance). 

During fermentation, which can last 1 – 6 months, yeast breakdowns some of its inherent carbohydrates to alcohol. At this point, the result is the alcoholic cider (also known as applejack).

Fermenting for a second time will convert apple cider to apple cider vinegar. Apple cider contains about 1-8% of alcohol, which acetobacter – a beneficial bacteria – converts to acetic acid. It is acetic acid that gives the vinegar its distinctive sour and acidic flavor.

Do you have to store apple cider vinegar in the fridge?

No, you don’t have to store apple cider vinegar in the fridge. As mentioned, apple cider vinegar is self-preserving. In fact, vinegar is used as a preservative for other foodstuffs, like salad. So it does not need refrigeration. You can store it in a dark cupboard or the pantry, out of direct sunlight.

The label on your store-bought apple cider vinegar bottle is the first place to look for information. You don’t have to store it in the fridge unless it says “refrigerate after opening.” Vinegar is sour and fermented (in a way – spoilt); thus, it will not deteriorate under room temperature.

How long does apple cider vinegar last?

Apple cider vinegar will last for as long as the expiration date and for many years after. For example, manufacturers of Bragg’s Apple Cider Vinegar report that owing to its attributes, their product can be safely used for several years after its best-by date.”

Keep in mind that this does not imply that the vinegar will remain unchanged. Vinegar may have altered appearance as it matures, such as becoming murky or precipitating. At the bottom of the bottle, you may detect murky sediments or threads.

This change is mostly due to air exposure, which occurs every time you access the vinegar and generates citric acid and sulfur dioxide. These compounds may impact how it tastes or contributes to a dish, but it has a negligible effect on the nutritional content or shelf life of apple cider vinegar

Besides, there’s rarely a reason to toss an old bottle of ACV. If you don’t like the taste of expired apple cider vinegar, use it for cleaning purposes instead. It’s still one of the healthiest products on your shelf!

Besides, there’s almost never a need to throw away any expired or old bottle of apple cider vinegar. If you dislike the flavor of the old vinegar, you can use it for cleaning alternatively!
