Olive oil is a staple in many kitchens today. However, many people may not store it correctly. Proper storage is vital for several reasons. Follow this guide to keep your extra virgin olive oil tasty until the last drop!

Where to Store Your Olive Oil?
Olive oil needs to be kept away from heat and light. The best place to store your olive oil is in a cool, dark area, like a cupboard. Avoid placing it near the stove or oven, where heat can affect the oil. It’s also important to keep olive oil in an opaque bottle to prevent light exposure.
Oxygen can also negatively impact olive oil. Make sure the bottle is tightly sealed when not in use to minimize oxygen exposure. It’s advisable to choose a bottle size that you can consume within 3-4 months. Avoid refilling bottles, as this adds more oxygen and leaves residues at the bottom.
Why Is Proper Olive Oil Storage Important?
Olive oil is extracted from ripe olives, making it essentially a fruit juice. Improper storage can alter its flavor. If not stored correctly, olive oil may become rancid, giving an unusual and unpleasant taste to your dishes. Even a small amount can spoil the flavor of your meal. Additionally, rancid olive oil emits an unpleasant odor that can affect the overall taste of your dishes.
Extra virgin olive oil is known for its antioxidant properties and high levels of healthy polyphenols and monounsaturated fats. However, these benefits diminish when the oil goes bad. Proper storage is crucial to maintain its quality. A bottle of extra virgin olive oil usually has a harvest date indicated. If kept away from heat and light, it can remain unopened for up to two years. According to the International Olive Council, the best-by date is up to 24 months from the bottling date. Once opened, regardless of whether it's before or after the two-year mark, the olive oil should be consumed within three to six months.

Tips for Maintaining Olive Oil Quality
To ensure your olive oil remains fresh and flavorful, consider the following tips:
Choose the Right Container: Use dark glass or tin containers to protect your oil from light.
Store in a Cool Place: Keep your olive oil in a pantry or cupboard away from heat sources.
Seal Tightly: Always close the bottle tightly after each use to limit oxygen exposure.
Avoid Large Containers: Opt for smaller bottles to reduce the amount of air exposure each time you open it.
