With proper storage, our essential oils should maintain their shelf life for about one year.

Essential oils will last the longest if stored in an airtight container and refrigerated. We recommend refrigerating separately from food to avoid cross-contamination and for increased safety. This storage method helps to slow oxidation and provides the longest shelf life possible. 

Storing essential oils at room temperature or exposing them to excessive sunlight or heat can reduce their shelf life to about six months. Citrus essential oils tend to be particularly sensitive to excessive sunlight and heat. 

We recommend testing each essential oil in a small batch before making a large batch if you have any concerns. Changes in the smell, color, or consistency typically indicate that an essential oil is past its prime. Writing the date you first opened the bottle on the label is a convenient way to keep track of its age.
