Olives are typically reaped in the fall so that the newest olive oil will have a yield date from the most current autumn season.
Suggestions for how long does olive oil last or will stay refreshed differ by manufacturer.

While oxygen molecules can enable us to stay healthier and hopefully stay alive longer, antioxidants themselves do not live. After time oxidation will start, indicating the oil will disintegrate down. This occurs more speedily when they are revealed to light and air, which is the reason organizations such as the California Olive Oil Council suggest selecting oils that are packaged in dark glass or tin bottles.
