Expiration & Storage Tips
When does extra virgin olive oil expire?
An unopened bottle of extra virgin olive oil (EVOO) usually remains at peak flavor for about 18 to 24 months from the time of bottling, or usually a year from the purchase date. Once opened, EVOO should ideally be used within three to six months for best flavor. Despite these guidelines, it's good to note that EVOO doesn't 'expire' in the traditional sense, but its flavors start to deteriorate and lose their freshness after the recommended span. Freezing olive oil is also an option, which will extend the oil's life by several years, although it can affect the texture and flavor slightly when thawed.
How do you tell if extra virgin olive oil is bad?
Check for a sour smell or taste, as this is an indication that the oil has turned rancid. The oil might also look a bit cloudy if it's going bad. Remember, good EVOO should have a fresh, fruity, grassy or peppery smell and flavor, it should not smell stale or old. Additionally, its color can also indicate its status. While color can vary from green to golden, a particularly dark color could suggest the oil is old, but don't use this as the only indicator. Always trust your nose and your taste buds!
Tips for storing extra virgin olive oil to extend shelf life
• Store the oil in a cool and dark place, ideally in a pantry and away from heat sources like the stove or oven.
• Make sure the EVOO bottle cap is tightly sealed after each use to minimize exposure to air.
• If available, consider storing your oil in a dark glass or tin container to protect it from light that can degrade its quality.
• Limit the oil's exposure to oxygen. Use smaller bottles if possible or transfer the oil into a smaller bottle as you use it.
• If you choose to freeze your olive oil, pour it into an airtight container leaving some space for the oil to expand as it freezes.
