The Art of Storing Olive Oil: How to Keep Your Olive Oil Optimally Fresh
Olive oil is an investment in flavor and health, but only if you store it properly. Incorrectly stored olive oil loses not only its flavor but also its valuable health benefits. Here's how to keep your olive oil optimally fresh.
The Three Enemies of Olive Oil
Olive oil has three major enemies: light, heat, and oxygen. These elements accelerate the oxidation process and turn your precious olive oil rancid.
Light: UV rays break down the delicate structure of olive oil. Therefore, always store in dark bottles or cans.
Heat: Temperatures above 20°C accelerate spoilage. The ideal storage temperature is between 14-18°C.
Oxygen: Once opened, oxidation begins. Always keep the bottle tightly closed.
Canned Olive Oil: Pros and Cons
5-liter cans are popular with frequent users, but require extra attention:
Advantages:
- Completely protected from light
- Cost-effective for high usage
- Long shelf life unopened
Storage strategy for large cans:
- Transfer smaller quantities into dark bottles
- Use within 2-3 months after opening
- Store the can in a cool, dry place
Shelf Life: How Long is Olive Oil Good?
Unopened extra virgin olive oil will keep for 18-24 months. Once opened, it's best to use it within 3-6 months. Look for the following signs of spoilage:
- Musty or rancid odor
- Cloudy appearance
- Bad aftertaste
Olive Oil in the Fridge?
This is a frequently asked question. Refrigerator storage is possible, but not necessary. Olive oil can become cloudy or solidified in the refrigerator, but this doesn't affect its quality. Let it come to room temperature before using.
Storage Tips from the Professionals
- Buy smaller bottles if you don't use much
- Use a dark, cool pantry
- Replace old olive oil regularly
- Pay attention to the harvest date, not just the shelf life
