How long does olive oil last?
The shelf life of olive oil can depend on several factors, including its type (also known as grade), method of treatment, and storage conditions.
Olive oil is not strictly regulated by the FDA, USDA Grading standards are set.
Olive oil is the most common type of food store:
Extra Virgin Olive Oil (EVOO): The most popular choice known for its rich flavor and high quality. Widely available and used for dressing, soaking and light cooking.
Pure (virgin) olive oil: A blend of sophisticated olive oil and virgin olive oil, often sold simply as “olive oil.” It has a mild taste and is commonly used for general cooking.
Light olive oil: Despite its name, it has few calories. A refined oil with a neutral flavour, perfect for high-heat cooking.
Infused Olive Oil: A variety of seasoned olive oil by adding herbs, spices, fruits or other ingredients after the oil has been extracted. It is often used to lightly rain over salads, soak bread, or throw it on pasta dishes.
Extra virgin olive oil usually lasts for 6-12 months. Sophisticated (processed) olive oil, if properly stored, lasts approximately 12-18 months from the opening.
General guidelines for olive oil storage
| Types of olive oil | Unopened shelf life | Opened shelf life |
| Extra virgin olive oil | 12-24 months | 6-12 months |
| Pure (virgin) olive oil | 18-24 months | 6-12 months |
| Light olive oil | 12-18 months | 3-6 months |
| Infused olive oil | 6-12 months | 3-6 months |
How olive oil spoils
Like other foods, olive oil can deteriorate over time.
Includes signs of olive oil spoilage:
Olive oil can oxidize and oxidize, resulting in an unwanted taste and smell.
Includes notable signs:
odor: It has a waxy smell instead of a fresh, grassy scent.
taste: Bitter, metal, or old flavors.
Colors and Textures: Discoloration, turbidity, or accumulation of sediment in the bottle.
If you notice any of these signs, it is best to throw away the oil. Vigorous olive oil can lose its health benefits and develop harmful free radicals.
Factors that influence the freshness of olive oil
Several factors affect the time that olive oil remains fresh, including:
temperature: Heat speeds up the oxidation of olive oil and breaks down faster. Store at 50-70°F (10-21°C).
Light exposure: UV rays break down healthy fats, use dark bottles, and store them in pantry.
time: Olive oil loses its quality over time, even if it is not open. It is best to use within 18-4 months from the harvest date.
Oxygen Exposure: Air breaks down the quality of olive oil. Always keep the bottle tightly sealed.
Processing method: Extra virgin olive oil ruins faster than refined olive oil due to its high polyphenol content.
Whether you’re using extra virgin olive oil, refined olive oil, or infused olive oil, proper storage is key to maintaining flavor and nutritional quality.
How to know if olive oil is fresh
Unlike wine, olive oil does not improve with age. It is best to be consumed freshly to enjoy its optimal flavor and health benefits. There are several important ways to know if olive oil is fresh.
Taste and smell: Fresh olive oil should have a fruity aroma and peppery flavor. Sour olive oil may smell like crayons or have an old, bitter taste.
Harvest date: Though not essential for the FDA, many high-quality olive oil producers have harvest dates and a “Best by” date on their labels so that consumers can rate their freshness. This will tell you when the olives are harvested and help you measure the freshness of the oil.
package: Choose olive oil in a dark glass or stainless steel container to protect it from light and air.
Is olive oil still having health benefits after its expiration date?
According to California Olive Oil Council:
As the oil ages (after its expiration date), antioxidant nutrients decrease, but there is no change in the fatty acid profile. Therefore, in terms of antioxidant nutrients, the health benefits of EVOO can be reduced, but its overall benefits do not disappear completely.

So, if the oil has passed the label expiration date, but still tastes fresh and smells, it may still be healthy.
Proper storage and handling
Storage Guidelines
- Keep olive oil in a dark and cool place and avoid storing it near a stove or window.
- Use an airtight container to minimize air exposure.
- Do not store olive oil in plastic for a long time. Glasses and tin are the best.
Do I need to refrigerate the olive oil?
Some people refrigerate olive oil to extend shelf life, but this is not necessary unless you live in a hot climate.
- Strong Points: Refrigeration slows down oxidation.
- Cons: Cold temperatures cause the olive oil to become cloudy and thick, but return to normal at room temperature.
If you want to refrigerate olive oil, the choice is up to you. However, you may need to warm it up before use.
How to extend the shelf life of olive oil
To keep olive oil fresh for longer:
- Store properly according to the above guidelines.
- Use a dark glass bottle to limit bright exposure.
- If you don’t use olive oil frequently, buy a small amount.
- Avoid excessive air exposure. Always keep it firmly sealed after use.
