Wood-pressed oils are pure, unrefined, and chemical-free, making them the perfect choice for a healthy lifestyle. However, since they lack preservatives, proper storage is essential to maintain their freshness, aroma, and nutritional benefits.
In this guide, we will share expert tips on how to store wood-pressed oils correctly and prevent them from going rancid.

Why Proper Storage is Important?
Unlike refined oils, wood-pressed oils retain natural nutrients, but they are also more sensitive to:
✔️ Light – Can break down nutrients and cause oxidation.
✔️ Heat – Speeds up the oil’s degradation process.
✔️ Air Exposure – Leads to rancidity and loss of health benefits.
✔️ Moisture – This can lead to spoilage or fungal growth.
To keep your oil fresh for longer, follow these best storage practices.
1. Choose the Right Storage Container
The container plays a major role in preserving oil quality. Here’s what you should use:
✅ Glass Bottles (Dark-Colored) – Brown or green glass bottles protect the oil from light exposure.
✅ Stainless Steel Containers – Ideal for long-term storage as they prevent oxidation.
✅ Ceramic Jars – Maintain oil purity and prevent contamination.
🚫 Avoid Plastic & Transparent Bottles – They can leach harmful chemicals and expose the oil to light, reducing shelf life.
2. Store in a Cool, Dark Place
Heat and direct sunlight break down essential nutrients in wood-pressed oils.
✔️ Keep bottles in a kitchen cabinet away from the stove.
✔️ Avoid storing oils near windows or in direct sunlight.
✔️ If you live in a hot region, store oil in a clay pot or a cool pantry.
💡 Tip: Refrigeration is optional, but it helps extend the shelf life for certain oils like coconut oil & flaxseed oil.
3. Keep the Lid Tightly Sealed
Exposure to oxygen can cause oxidation, leading to a change in taste and smell.
✔️ Always seal the bottle immediately after use.
✔️ Use small bottles for daily use & store larger quantities separately.
✔️ If using oil from a tin, transfer it to an airtight bottle.
💡 Tip: Oxygen can spoil oil faster. Try using a pump dispenser instead of repeatedly opening the cap.
4. Store Different Oils Separately
Each oil has a different shelf life and storage requirement. Avoid mixing them to retain their original aroma and taste.
✔️ Coconut Oil: Best stored in a cool place, solidifies in cold weather.
✔️ Mustard Oil: Should be stored in glass or stainless steel to prevent odor contamination.
✔️ Groundnut Oil: Keep in a cool, dry place to prevent oxidation.
✔️ Sesame Oil: Store in a dark bottle to protect its antioxidants.
🚫 Do Not Mix Different Oils Together – This can change their chemical composition and reduce health benefits.
5. Use Within the Recommended Shelf Life
Since wood-pressed oils are free from preservatives, they have a limited shelf life:
🥥 Coconut Oil: 12–18 months
💛 Mustard Oil: 6–12 months
🌰 Groundnut Oil: 6–9 months
🌻 Sunflower Oil: 6–9 months
🌿 Sesame Oil: 12 months
💡 Tip: Buy oils in small batches to ensure freshness. Avoid storing oil for too long, as it may lose its nutrients.
6. Smell & Taste Test to Check Freshness
To check if your oil is still fresh and safe to use, follow this simple test:
✔️ Smell Test: Fresh oil has a natural aroma, while rancid oil smells sour or off-putting.
✔️ Taste Test: If the oil tastes bitter, metallic, or sour, it has gone bad.
✔️ Texture Test: Cloudy oil can indicate moisture contamination (except coconut oil, which solidifies naturally).
🚫 If your oil smells or tastes bad, discard it immediately!
Bonus Tips for Keeping Oils Fresh
🔹 Buy in Small Quantities – Purchase fresh oils every 3–6 months.
🔹 Use a Dry Spoon – Never let water or moisture enter the oil bottle.
🔹 Avoid Storing Near Spices – Strong aromas can get absorbed into the oil.
