Olive trees can live up to an impressive 2000 years, but the oil produced by the fruit certainly has a shorter shelf life. Sometimes referred to as a juice, the best olive oil is harvested once a year with great care, as the olives are handpicked. This makes it one of the best oils you can keep on hand, though if you do not like the taste, there are plenty of others to choose from.
There is a big difference in the types of olive oils available, and all have different flavor profiles and health and baking properties. For those seeking the highest quality, extra virgin olive oil stands at the pinnacle of the olive oil grading scale. We will discuss the best way to store this, as it is the most sensitive one!
How To Store Olive Oil?
To maintain the numerous health benefits and flavor of olive oil, you gotta store it properly. Incorrect storage can lead to rancidity, which not only affects the taste but also diminishes the quality.
Always store olive oil in a dark and cool space. Heat, light, and oxygen are the archenemies of olive oil, so shield it from these elements to preserve it. For this reason, the best kinds of olive oil will be sold in dark glass bottles – they prevent the light from getting in and oxidizing the oil!
When choosing the perfect place for your olive oil, it’s best to:
- Keep olive oil away from heat sources such as stoves, ovens, and the top of the refrigerator.
- Prevent exposure to direct sunlight and fluorescent lighting, as they can hasten the degradation process.
- Minimize air contact to reduce oxidation and maintain the oil’s antioxidants.
Olive oil can also be stored in the fridge, but this tends to go cloudy and affect the texture quite a bit, making it difficult to pour. However, if you don’t have anywhere cool to put it, the fridge might be your only option.
Can You Freeze Olive Oil?
Yes, it is indeed possible to freeze olive oil. In fact, when the temperature drops to around 54 degrees Fahrenheit, olive oil starts to solidify. As it reaches about 10 degrees Fahrenheit, it fully freezes. In the United States, most refrigerators are typically set at around 40 degrees or slightly below, while freezers are kept at 0 degrees.
Freezing olive oil is a good idea if you have a fresh batch of extra virgin that you know you won’t use very fast. You can portion the oil out using ice cube trays and pop them in the freezer, then just remove as many as you need to use when it is time.
The chemical composition of each olive oil batch can vary slightly, depending on factors like the type of olives used, the harvesting process, and any refining that was performed. Consequently, the solidifying and freezing temperatures may differ from one batch – and even one bottle – to another.
When olive oil solidifies, it does not do so all at once; it goes through stages. Initially, the liquid becomes cloudy, thanks to the solidification of triglycerides and naturally occurring waxes. These particles give the oil an opaque appearance. If the olive oil is left in cool temperatures for an extended period, the entire bottle will eventually solidify and turn opaque.
How To Defrost Olive Oil
To defrost frozen olive oil, the safest approach is to allow it to thaw naturally at room temperature until it reverts to a liquid consistency. This may take several hours, depending on the temperature. You can expedite the process by immersing the frozen olive oil package in warm water.
Do not use the microwave or the stovetop to thaw or melt the olive oil, as this may alter the taste and odor of the oil. Avoid leaving opened olive oil bottles in warm areas, as they can easily spoil due to oxidation.
How Long Does Olive Oil Last?
There are a lot of variables when it comes to how long olive oil lasts. For instance, refined oils and olive pomace oil will have a longer shelf life. Extra virgin olive oil, on the other hand, has a limited life span. It reaches peak freshness when closely aligned with its harvest date and progressively loses freshness over time. Dark glass bottled olive oil is typically good for 1.5 to 2 years or 1 to 1.5 years from its harvest date, as indicated on higher quality oils.
Upon opening the bottle, proper storage becomes crucial to prevent faster expiration. As a general guideline, it is recommended to use opened olive oil within 60 days or up to a year at most. Quite a broad timeline!
Optimal storage conditions can prolong the shelf life of olive oil, lasting between 18-24 months. Freezing the oil significantly extends this period without compromising its characteristics or quality.
How To Know When Olive Oil Is Rancid?
Since extra virgin olive oil is prone to speedy oxidization, trusting your eyes and nose to check the quality before dumping it onto your salad is super important!
If you keep your olive oil in a refillable bottle, it can speed up the spoiling process. If they are not cleaned properly or if old oil is continually replenished with new oil, the fresh oil can be affected, spoiling all of it.
Good olive oil should smell almost a little grassy. Bad olive oil smells like old rubber or overused frying oil. You may also notice color changes. Once opened, a good olive oil should remain a light green or yellow, while a bad one may darken and develop a brown tint.
While eating a little rancid olive oil is not likely to make you ill, it doesn’t taste good. It can vary from stale and flat tasting to sour or bitter, as opposed to the fresh and peppery taste of good olive oil.
FAQs
