Olive oil does go bad after a while. It might look like it will last a long time, but because it's made from olives, it naturally goes bad over time. The aging process changes the oil's taste, how fresh it is, and its health benefits. Whether it's extra virgin or refined olive oil, the best way to keep the quality and keep rancid oil from ruining your food is to store it correctly.

How Long Does Olive Oil Last?

Some olive oils go bad after a while. Most of the time, an olive oil bottle is good for 12 to 24 months after it was picked. But how you store olive oil has a big effect on how long it lasts and how fresh it is.

• Extra Virgin Shelf Life: Extra virgin olive oils typically last 12–18 months.

• Refined Oils: Since it goes through more steps, refined olive oil can last up to 24 months.

• Unopened Bottles: Olive oil that hasn't been opened will last longer, but it will still go bad over time.

• Opened Oils: Once the oil is opened, it starts to lose its natural antioxidants because it is exposed to oxygen.

• Check the Date: On the label, you should always look for a best-before date or harvest date.

What Shortens Olive Oil's Lifespan?

There are a few things that can make olive oil go bad faster. The oxidation process starts as soon as air, light, and heat hit the oil. This process will go faster if the storage conditions are poor.

• Light Exposure: The oil breaks down when it's in direct sunlight or a bright kitchen.

• Heat Sources: Putting olive oil near stoves or other warm appliances makes it age faster.

• Air Contact: When the bottle is opened, oxygen gets in, and oxidation takes place.

• Packaging: Oils in clear bottles or containers made of plastic break down faster. Tin or dark glass should be used.

• Storage Tip: Keep olive oil in a cool, dark place at all times, like a cabinet or pantry.

Is Expired Olive Oil Safe to Use?

Small amounts of expired olive oil aren't bad for you, but they won't give you the health benefits or flavor of new olive oil. If you don't use good olive oil, your dish will turn out badly, and you won't get the health benefits of extra virgin oils. While you don’t need to worry about getting sick, it’s better to cook with oils that are still fresh.

Can Rancid Olive Oil Make You Sick?

Old oil typically doesn't cause acute illness, but prolonged intake of rancid oils may have negative health implications due to degraded compounds. However, the healthy fats and antioxidants that make olive oil good for you are lost during the oxidation process. Also, olive oil that has gone bad can ruin the taste of your food.

• Taste Issues: When olive oil goes bad, it makes other foods taste bitter and greasy.

• Health Impact: When oil is oxidized, it loses its natural antioxidants and is less good for you.

• Safe but Unpleasant: It can be used to cook, but it won't make salads or bread better.

What Happens If You Eat Expired Oil?

While consuming a small amount of expired oil is unlikely to be harmful short term, it may lack health benefits and degrade flavor. Bad olive oil may smell like crayons, putty, or stale nuts, not typically like rotten eggs, which indicates sulfur compounds not present in olive oil. Spotting signs of spoilage helps keep your food and dishes safe.

• Smell Check: Bad oil will smell waxy, like glue or crayons.

• Taste Test: Don't use it if it tastes bad, bitter, or old.

• Visual Signs: Check for cloudiness, strange colors, or seals that are broken.

• Storage Tip: If you don't use oil very often, buy smaller bottles to maintain its freshness.

Is Olive Oil Good After 5 Years?

Even if it's not opened, most olive oils won't taste good after five years. Even if the bottle is closed, the oxidation process is still going on slowly. The oil's taste, smell, and antioxidants are mostly gone after five years. It might still be safe, but it's not good enough for cooking or salads.

Can Properly Stored Olive Oil Last 5+ Years?

It doesn't happen often, but some oils might last longer in ideal conditions. So keep olive oil somewhere cold and dark, away from heat, light, and air. Still, most producers say you shouldn't keep it that long.

• Ideal Storage Conditions: That means cool (around 55°F), no light, and containers that are tightly closed.

• Container Choice: Do not use plastic containers. Instead, use dark glass or metal tins.

• Fridge Storage: Refrigeration can cause extra virgin olive oil to solidify temporarily, which is harmless and reversible at room temperature. Give it some time to warm up again.

What Makes Old Olive Oil Unusable?

There are clear signs that the olive oil is no longer good. After 24 months, the food is more likely to go bad, especially extra virgin olive oil. Don't use it if it smells or tastes bad.

• Rancid Smell: If it smells like wax or putty, it's gone bad.

• Loss of Flavor: Doesn't taste good or have bad smells = expired.

• Appearance Changes: Damage could be shown by oil that is cloudy or thick.

• Use Elsewhere: Some suggest reusing mildly expired olive oil for non-edible purposes like polishing wood, though this should only apply to mildly degraded oils and not those with mold or microbial spoilage.

What Are Three Signs Your Olive Oil Is Spoiled?

Olive oil can go bad even if it looks fine on your counter. Oil doesn't last forever because it is a natural product made from olives. The oil breaks down when it comes in contact with air, light, and heat. This makes it less healthy, less tasty, and less effective. To keep your food safe and fresh, you need to know how to spot bad oil.

The Smell Test

There's a simple way to tell if your olive oil is still good: smell it. The aroma of fresh olive oil is nice and fruity. If you smell something strange or waxy, that's a red flag. Olive oils lose their natural smell and may start to smell funny when they go bad.

• Smell Clue: If the olive oil smells bad, like crayons or putty, it's no longer fresh.

• Air Exposure: The smell changes because air breaks down the fats in the oil.

• Container Tip: Store olive oil in a tight, sealed container to protect it from air.

• Storage Reminder: Keep it somewhere cool and dark, never on the counter near heat.

Look and Taste Changes

Fresh olive oil should be green or golden and taste clean and smooth. It changes both how it looks and how it tastes when it goes bad. In cold weather, it may cloud over or solidify, which isn't always a bad thing. But if it smells or tastes bad, throw it away.

• Taste Check: If the oil tastes old, bitter, or metallic, it's no longer good.

• Visual Sign: Cloudiness in a warm room could mean that the food has gone bad, not just that it was stored in the cold.

• Color Changes: If it's a darker color than usual, it might be old or broken.

• Use Your Senses: Smell, taste, and look can all help find spoilage.
