How to store oils: Tips for preserving taste and quality
Oil is an everyday kitchen staple, but can we store it properly? It might seem simple—we place it on a shelf or in a cabinet and use it when needed. However, some types of oil require special storage, and their taste and quality can quickly change if not kept under the right conditions.

We often overlook whether we're storing oils correctly, yet their quality and freshness significantly impact the taste of our dishes. Improper storage can lead to faster oil oxidation, causing it to lose nutritional value and potentially develop a bitter taste.
Which oils should be kept in the refrigerator?
Not every oil requires the same storage temperature. Most of us store vegetable oil on the kitchen counter or in a cabinet, but some oils are best kept in the refrigerator to maintain their freshness and beneficial properties. Examples include cold-pressed oils, such as flaxseed oil, evening primrose oil, and walnut oil. These oils are sensitive to light and temperature, and storing them in a warm location can cause them to spoil quickly.
Flaxseed oil, known for its health benefits, should always be kept in the refrigerator. It is rich in unsaturated fatty acids, which are highly susceptible to oxidation. Exposure to light and heat can cause it to lose its nutritional value and even alter its taste. The same goes for other cold-pressed oils—their delicate structure requires cooling to maintain freshness longer.
Which oils can be kept outside the refrigerator?
Canola oil, sunflower oil, and olive oil are more stable and can be stored at room temperature as long as they are kept away from direct sunlight. To protect them from oxidation, they should be stored in dark, airtight bottles. Although olive oil is relatively durable, long-term storage in warmth should be avoided; it's best kept in a cool, dark place.
Oil components, such as fatty acids and vitamins, are sensitive to light and air exposure. Therefore, we should always ensure that the bottle is well-sealed after use to preserve its quality and health benefits for longer.
Why is it important to know how to store oils?
Proper storage of oils is crucial for their quality and taste. Poorly stored oil can quickly lose its properties and even taste bitter. Cold-pressed oils, rich in valuable omega-3 fatty acids, are particularly sensitive and require refrigeration to enjoy their full flavour and health benefits.
If we've been storing all oils in one place, it's worth considering moving some to the refrigerator. This can not only extend their freshness but also improve kitchen results.
