Store olive oil in a dark or opaque container (or if its in a clear container, in a dark place). When olive oil is exposed to sunlight, its quality is degraded. Prolonged oxygen exposure will also overpower those natural protectants and cause rapid degrading that leads to rancid olive oil. You know your olive oil is rancid if it smells and tastes like crayons.
