Does Olive Oil Expire?

Most olive oils can last 18–24 months from the time they're bottled, while extra virgin olive oils may last a bit less — around 12–18 months. Beyond this time, it will go rancid. To avoid this, store it in a cool, dark place and toss it if the best-by date has passed.

How do you know if olive oil has gone bad?

"When it's bad, it doesn't smell fresh and fruity. If it smells waxy, like crayons, it's gone." If you're having trouble going by scent alone, swirl a bit in your mouth. You'll know it's rancid if it's generally unpleasant and overly greasy.

What happens to olive oil when it expires?

Is it OK to use expired olive oil? It depends. Cooking with rancid olive oil won't make you sick like eating spoiled meat would, but it's likely lost any nutritional value or antioxidants. Also, it will definitely make your food taste weird.
