The Finest Harvest in Every Bottle:

PDO/DOP Certified Extra Virgin Olive Oils

Understanding Shelf Life

The shelf life of extra virgin olive oil (EVOO) depends on various factors, including production methods, storage conditions, and packaging. Generally, EVOO can last 18-24 months from the harvest date. However, once opened, it is best to use the oil within 3-6 months for optimal flavor and nutritional benefits. Proper storage can significantly extend the shelf life and maintain the quality of the oil.

Storage Conditions

Store EVOO in a cool, dark place away from heat and light. Proper storage helps maintain its quality and extend its shelf life. Avoid storing EVOO near the stove or in direct sunlight, as heat and light can accelerate the oxidation process and degrade the oil. The ideal storage temperature for EVOO is between 57°F and 70°F (14°C and 21°C).

Packaging Matters

Dark glass bottles or stainless steel containers are ideal for storing EVOO. These materials protect the oil from light exposure, which can degrade its quality over time. Avoid using clear glass or plastic containers, as they do not offer the same level of protection. Ensure that the container is airtight to prevent exposure to air, which can also lead to oxidation.

Signs of Spoilage

Rancid EVOO will have a musty, sour smell and taste. If your oil has these characteristics, it is no longer fresh and should be discarded. Other signs of spoilage include a greasy texture, dark or cloudy appearance, and a lack of the vibrant, fruity aroma typical of fresh EVOO. Using spoiled EVOO can negatively affect the flavor of your dishes and may not provide the same health benefits.

Expert Tips

Olive oil producer John Carmichael advises, "Proper storage is crucial to maintaining the quality and flavor of extra virgin olive oil. Always check the harvest date and use the oil within the recommended time frame. Store the oil in a cool, dark place and use dark glass bottles or stainless steel containers to protect it from light."

Common Mistakes to Avoid

Here are some common mistakes to avoid when storing EVOO:

• Storing Near Heat Sources: Avoid storing EVOO near stoves, ovens, or other heat sources, as heat can accelerate oxidation and spoilage.
• Using Clear Containers: Clear containers do not protect the oil from light exposure, leading to faster degradation. Always use dark glass or stainless steel containers.
• Leaving Bottles Open: Exposure to air can cause the oil to oxidize and lose its quality. Keep the bottle tightly sealed when not in use.
• Long-Term Storage in Plastic: Plastic containers can leach chemicals into the oil over time. For long-term storage, use glass or stainless steel containers.

Refrigeration

Refrigerating EVOO can help extend its shelf life, especially in warmer climates. While refrigeration may cause the oil to become cloudy and solidify, this does not affect its quality. Simply allow the oil to return to room temperature before using it. For long-term storage, refrigeration can be a good option, but for everyday use, storing the oil in a cool, dark pantry is sufficient.
