Expiration & Storage Tips
When does olive oil expire?
Unopened olive oil should stay fresh for about one to two years when stored in a cool, dark place. However, it's always a good idea to check the 'best by' date on the label to ensure freshness. Once opened, the oil typically lasts about six months if stored correctly. If you choose to freeze olive oil, it can extend it’s life by several months and the quality or taste should not be affected. Just be aware that at freezing temperatures, olive oil may solidify or turn cloudy, but it will regain its normal appearance once defrosted at room temperature.
How do you tell if olive oil is bad?
How to tell if olive oil is off can sometimes be a bit tricky as it doesn't grow mold or turn visibly bad like some other foods. The best way to know for sure is by smelling and tasting it. If the oil has a rancid or sour smell, or if it tastes bitter, stale or off in any way, it's likely gone bad. Quality olive oil should smell fresh, fruity or slightly grassy, and shouldn't leave a greasy or waxy aftertaste.
Tips for storing olive oil to extend shelf life
• Keep the oil stored in a cool, dark place away from heat and light, which can degrade its quality. A pantry or kitchen cabinet that stays below room temperature and is away from the stove or other heat sources is ideal.\n\n• Use dark glass or tin containers for storage. They keep light out better than clear containers, helping to maintain the oil's quality.\n\n• Always screw the cap back on tight after each use to protect it from exposure to air, which can also degrade the oil.\n\n• If you've opened a bottle of olive oil, try to use it within six months for optimal flavor.
