Olive Oil That hasn’t been Kept in the Refrigerator Runs the Risk of Going Rancid Very Quickly.
Olive oil can be stored for up to 24 months at room temperature; extra virgin olive oil, on the other hand, can be stored for up to 18 months. Neither type of olive oil needs to be refrigerated; in fact, doing so may hasten the process by which it deteriorates.
Olive oil should be stored in a cool, dark location. Cooking oil, on the other hand, is not the same as olive oil and should not be treated in the same manner. Cold temperatures increase the likelihood that olive oil will become cloudy and solidify. There is a discernible difference in both taste and appearance.
