Recommended Storage The ideal storage of essential oils is to keep it refrigerated, as the fridge keeps the components that make up the oils at their optimal levels. If you don't have space in the fridge, you can keep it in a cool, dark place. Essential oils have a shelf life of one to five years. You should however replace essential oils after three years to gain the most benefits out of the essential oils.
