To maximize shelf life, olive oil should be stored in a cool, dark place and kept tightly sealed at all times. While there is no strict timeline on how long you can keep an olive oil once it has been opened, our recommendation is to use all of the oil within a few months. Some people ask if it’s good to refrigerate olive oil. Research suggests that repeated heating and cooling, as would happen with refrigerating between each use, puts too much stress on the oil and doesn’t extend the shelf life. Olive oils degrade naturally over time, and an olive oil past its prime will eventually become rancid. Ensure your olive oil has a fresh aroma before every use. If your oil does not have a fresh (olive) fruit smell, throw it away, and head to your local store.
