Does olive oil expire?

Olive oil is an essential product in Mediterranean cuisine and culture, recognized for its flavor, nutritional properties and versatility. However, one of the most frequently asked questions about olive oil is whether it expires. Here we clear up all your doubts.

Olive oil expires: Yes or no?

Technically, olive oil does not “expire” in the traditional sense, as do other perishable foods. Instead of having a strict expiration date, olive oil has a best-before date, which indicates until when the product retains its optimum properties of flavor, aroma and quality.

Although it does not become a hazardous food after that date, its quality may decline significantly over time. This is because olive oil, like any fat, is susceptible to oxidation and rancidity processes. Factors such as exposure to light, heat and oxygen can accelerate this deterioration.

The best-before date for olive oil

The best-before date is usually between 12 and 24 months after the oil has been produced. This period may vary depending on the type of oil (extra virgin, virgin or refined) and how it has been stored.

In the case of extra virgin olive oil or EVOO, it is the highest quality oil and has the longest shelf life due to its content of natural antioxidants, such as polyphenols. If stored correctly, it can maintain its quality for about two years.

It is important to note that the best-before date is a guideline. If the oil is kept in a cool, dry and dark place, it is possible that it will remain in good condition even after that date.

How do we know if the oil is good?

Although olive oil does not expire in the literal sense of the word, it can deteriorate. Here are some tips to identify if the oil is still good or if it has started to lose its properties:

1. Observe its appearance: fresh olive oil usually has a color that varies from green to golden, depending on the variety and the production process. If you notice that the oil has a cloudy color or abnormal sediments, this could be a sign of deterioration.
2. Smell the oil: the aroma of olive oil is one of its most distinctive characteristics. A fresh oil should smell of fruit, freshly cut grass or almonds, depending on the variety. If you detect a musty or musty smell, it is likely that the oil has begun to oxidize.
3. Taste its flavor: the flavor of extra virgin olive oil is unique: it can be fruity, bitter or spicy. If you notice a metallic, cardboardy or simply unpleasant taste when tasting it, it is a sign that the oil is in bad condition.
4. Check its texture: an oil in poor condition may become more vicious or lumpy. Although this is not as common an indicator as taste or aroma, it is another sign that the oil may have lost its properties.

To extend the shelf life of your olive oil and always enjoy its maximum quality, always store it in a dark, cool place, away from stoves or windows, use suitable containers such as dark glass or stainless steel and close the container tightly after use to minimize contact with oxygen.

Conclusion on whether olive oil has an expiration date

In short, although olive oil does not expire like other foods, its quality can deteriorate over time, especially if it is not stored correctly. The best-before date is a useful guide, but the most important thing is to pay attention to the signs that indicate whether the oil is still fit for consumption.
