You might be wondering, how long does olive oil last? It’s a good question, and one that even I’ve asked myself a few times when I found an old bottle stashed away in the pantry. Olive oil is a kitchen staple, and like all foods, it does have a shelf life. Let’s walk through how long olive oil typically lasts, how to store it properly, and how to tell if it’s gone bad.
How Long Does Olive Oil Last? Here’s What I’ve Learned
So, how long does olive oil last? Generally, an unopened bottle of olive oil can last between 18 to 24 months from the bottling date if stored properly. Once opened, the clock ticks a bit faster. Opened olive oil will last around 12 months before it starts to lose its freshness.
But here’s the thing I always keep in mind: these are just guidelines. The freshness of your olive oil can vary depending on factors like the type of olive oil and how you store it.
How to Store Olive Oil for Maximum Freshness
If you want to make sure your olive oil lasts as long as possible, proper storage is key. I always store my olive oil in a cool, dark place, like a cupboard or pantry. Avoid storing it near heat sources like the stove or in direct sunlight.
Here’s what I do:
- Keep the bottle tightly sealed: This helps prevent oxidation and extends the life of your olive oil.
- Use dark bottles: Olive oil usually comes in dark glass bottles for a reason. They protect the oil from light exposure, which can cause it to go rancid faster.
Does Olive Oil Go Bad?
Yes, even though it’s a natural product, olive oil can definitely go bad. If you’re wondering how long does olive oil last, it’s important to know the signs of spoilage. In my experience, bad olive oil will have a sour, musty smell, or even a bit of a metallic taste. Trust me, you’ll know when it’s off—it won’t taste or smell the same as fresh olive oil.
How to Tell If Your Olive Oil Has Gone Bad
I use a couple of simple tricks to tell if my olive oil has gone bad:
- Smell it: Fresh olive oil has a grassy, fruity aroma. If it smells sour, like crayons or putty, it’s probably past its prime.
- Taste it: A taste test will tell you a lot. Fresh olive oil has a rich, smooth taste with a slight peppery finish. If it tastes stale or off, it’s time to replace it.
Extra Virgin vs. Regular Olive Oil – Which Lasts Longer?
When asking, how long does olive oil last, you’ll want to consider the type of olive oil you have. Extra virgin olive oil tends to have a shorter shelf life than refined or regular olive oil because it’s less processed. The extra virgin variety is best used within 12 to 18 months unopened and about 6 to 12 months once opened.
Can You Use Olive Oil After the Expiration Date?
In my kitchen, I always check the “best by” date on the olive oil bottle, but that date is more of a guideline than a hard rule. If you store it well, olive oil can still be good a few months past the expiration date. Just make sure you do the smell and taste tests to ensure it’s still fresh.
Final Thoughts on Olive Oil Shelf Life
Knowing how long olive oil lasts is important to make sure you’re always using it at its best. Whether drizzling it over salads or using it in cooking, fresh olive oil enhances flavors and adds richness to dishes. Keep it stored properly, use it within a reasonable time, and you’ll always enjoy the benefits of this versatile oil.
