How To Store Olive Oil Once Opened? (3 tips to help your olive oil last longer)

Allow me to ask you a question… Where do you keep your olive oil? It’s alluring — and extremely handy – to store oil right next to the stove, within arm’s reach, but is it really the ideal spot?


Olive oil is a pantry essential that we use virtually every day, and whether you have a normal work-a-day oil or a luxury bottle of extra-virgin, the key to making sure it lasts is appropriate storage (ain’t that the truth).

Keep oil away from the stove and other heat sources. Olive oil can solidify and become cloudy when refrigerated. This doesn’t affect health or nutrition.


3 Tips To Keep Your Olive Oil lasting Longer (thank me later)

1. Store Olive Oil in the Right Containers


Try using a ceramic cruet. A ceramic cruet is especially useful for preserving olive oil since it not only shuts out light and air, but the thick ceramic sides help block out heat too. If you’re going to use a cruet, though, you have to wash it thoroughly before you refill it each time. Otherwise, you’ll be mixing older oil in with your fresh oil, which will of course impair the oil’s flavor. I really enjoy having a pour spout on my bottle of olive oil—it simply makes pouring it into a skillet so much easier—but I was scared it could let too much air in. The amount of air that comes in via the little aperture of the pour spout is not any worse than the amount of air that gets in every time you open your bottle of olive oil. You can acquire one of the spouts that has a cover on top for even greater air protection, albeit the ones with the tiny metal flap over the top are not actually air-tight.


2. Use That Bottle Up Within a Month


Light, air, and heat all contribute to the destruction of olive oil, she observes, particularly oxygen. The instant you open a bottle of olive oil (just like a bottle of wine), oxygen starts flooding it, and the deterioration process begins. How soon the oil gets rancid depends on numerous things, though, including where and how you keep it and the temperature of your kitchen. Try smelling the olive oil right after you open it and before every subsequent use—just like you’d sniff an open bottle of milk before using it to be sure it’s still fresh. You’ll know when your olive oil is turning rancid when you notice that it because it’ll start to take on a more crayon or Band-Aid scent. If you’re plowing through olive oil rapidly in your kitchen, storing it near to the fire is not the worst thing you can do—in fact she also stores her everyday cooking oil right by the stove, in a porcelain cruet with a pour spout.


3. If You Must Buy in Bulk, Go for a Bag-In-Box Option


Extra virgin olive oil may be costly, and it might be tempting to buy it in the largest bottle possible to save money. But the bigger the container, the more time the oil is going to be exposed to air, heat, and light until you finish it all up. That’s why, if you want to buy olive oil in bulk, try buying a bag-in-box container, which helps prevent air exposure. You’ve certainly seen this style of packaging for boxed wine, but it’s relatively new for olive oil. Keep your eyes open for it though—some places do carry it, and you can also order it online. If you keep the bag-in-box in a cold, dark spot, and decant the oil into a ceramic cruet (that you’ve cleaned thoroughly before refilling), you’ll be following all the recommended practices for how to preserve olive oil. (Just make sure you know you’re genuinely going to go through the full bag-in-box within a couple months before you make the commitment.)



Protect it from light

Extended exposure to light can decrease the quantity and quality of the antioxidants contained in olive oil. Olive oil should be bottled in dark glass or tin to cut down on light exposure. It should also be stored away from direct light as exposure to light substantially shortens the shelf life of extra virgin olive oil.


What is the Best Storage Temperature for Olive Oil?

The optimal temperature for keeping olive oil is 57°F, however, a regular room temperature of 70ºF works quite well provided the olive oil is stored in a dark environment where the temperature is reasonably steady.


Olive oil will harden at 36ºF, but it will revert to a liquid form as soon as the temperature rises. In colder weather, olive oil may get hazy, especially if the temperature of the storage space goes below 50ºF.


Do Flavored Olive Oils Have Different Storage Rules?

Some flavored olive oils have additives that may require refrigeration in order to preserve them. Others may not require refrigeration due of the procedure used for making the olive oil, thus it is essential to read the label carefully.


It is typically not safe to manufacture your own flavored olive oils at home and preserve them for any period of time…


Some flavoring ingredients may increase the growth of microorganisms and may only be properly introduced with commercial techniques. You may, however, produce handmade flavored olive oils if they are utilized quickly and any excess oil is disposed away.

3. What oil won’t solidify in fridge?


Canola oil doesn’t harden in the fridge, so marinades and salad dressings will stay free-flowing for preparation in advance.


4. Does avocado oil solidify in the fridge?


Opened avocado oil will normally keep for around 8 months when kept in the refrigerator. Refrigeration may cause the avocado oil to become hazy and harden, but this will not damage the quality or flavor – once the oil is brought back to room temperature, it will revert to its natural consistency and color.


5. Does sunflower oil solidify in the fridge?


Oils rich in polyunsaturated fats (like Sunflower Oil) harden in temperatures below -22˚ F (-30˚ C). Therefore, It is stated that if a monounsaturated fat like EVOO doesn’t solidify in the fridge, then it must be contaminated with a polyunsaturated fat that likes to remain in a liquid condition.



Final Thoughts

So, what did we learn in class today? Once opened, we now know to keep olive oil in a dark place away from the stove and other heat sources…


Refrigerate any remaining oil, but be in mind that cold temperatures can cause olive oil to solidify and become cloudy. This has no bearing on the health benefits or nutritional value.


Additionally, prolonged exposure to light can reduce the quantity and quality of antioxidants in olive oil. To reduce light exposure, olive oil should be bottled in dark glass or tin.


It should also be kept out of direct sunlight, as light drastically reduces the shelf life of extra virgin olive oil. Enjoy the rest of your day, always stay safe, and treat others with kindness and respect. Until next time!
