First, store your sticks in an airtight glass container to prevent air and moisture from entering with
Ceylon cinnamon sticks. I keep my container in a dark cool place, away from direct sunlight and heat sources like kitchen cabinets another good way is vacuum bags if you have a vacuum packer. This is especially helpful if you buy cinnamon in large quantities and want to store it longer. It's also important to avoid sudden temperature changes, as this can affect the quality of the cinnamon. If you need to use the sticks regularly, you can keep a small amount in your kitchen for convenience and keep the rest of your stock in a more stable environment.
