How do you store olive oil to maintain its freshness?

Created on 7th Jan 2023

In simple terms, the two main enemies of olive oil are oxygen and light, with temperature also playing a part. Exposure to any of these will lead to a reduction in quality of the olive oil. As such, EVOO should be stored in a cool, dark place, away from heat and light. Exposure to air can also lead to oxidation, so it's best stored in a sealed, opaque container (just like the Pomora tins!).

Proper storage of Extra Virgin Olive Oil (EVOO) is crucial to maintain its quality, flavour, and nutritional benefits. See here for What is Extra Virgin Olive Oil?.

Here are some guidelines on how to store EVOO (Extra Virgin Olive Oil):

Cool and Dark Location:
Store EVOO in a cool, dark place, away from heat sources and direct sunlight. Exposure to light and heat can accelerate the oxidation process, leading to a decline in the quality of the olive oil. All Pomora olive oil is stored in this way, in a darkened room under fixed temperature control.

Opaque Container:
A container that is opaque or tinted protects the olive oil from light, just like all Pomora tins. No light can penetrate through tins, unlike some glass bottles.

Airtight Seal:
Ensure that the storage container has an airtight seal to minimize exposure to air. Oxygen can contribute to the oxidation of the oil, affecting its flavour and nutritional properties. Pomora deliberately use smaller 250ml tins (opposed to 500ml, 1L, 5L etc) so as to maintain the quality of the olive oil, once the tin is opened. If your EVOO comes in a larger bottle, consider transferring a smaller amount to a dispenser with a pour spout to help minimize the exposure to air each time you open the bottle.

Avoid Temperature Fluctuations:
Keep the Extra Virgin Olive Oil at a consistent temperature and avoid drastic temperature fluctuations, as these can also impact the olive oil's quality. Ideally, store it in a small room, pantry or cupboard away from the the oven and stove.

Check the Expiry Date:
Pay attention to the expiry date on the olive oil tin or bottle. While EVOO has a longer shelf life compared to some other oils, it is still a perishable product, and using it within a reasonable time frame ensures freshness and quality of flavour.

Avoid Refrigeration:
While refrigeration can extend the shelf life of some oils, it's generally not recommended for Extra Virgin Olive Oil. Cold temperatures can cause the oil to solidify and develop a cloudy appearance. Storing it in the refrigerator may also alter its flavour.

By following these storage guidelines for EVOO, you can help preserve the quality and flavour of your Extra Virgin Olive Oil. It's important to note that the shelf life of EVOO can vary depending on factors such as the quality of the oil, storage conditions, and the time since it was opened. Using the oil within a reasonable timeframe after opening is generally recommended for the best culinary experience. All Pomora olive oil stands up in this regard, but please do bear the storage of olive in mind.
