How long does olive oil last after opening the bottle? Does olive oil go bad after opening?
An unopened bottle of olive oil lasts about 18 -24 months when stored in ideal storage conditions. The shelf life of the oil remarkably drops when the bottle is opened.
Permeation of oxygen is the main reason the quality of the oil stays fresh for a short time, 1-2 months.
This is the reason an open bottle of olive oil should be consumed within a few weeks’ time.
