Expiration & Storage Tips
When does peppermint leaf expire?
Unopened and dry peppermint leaves can last quite a long time, usually about 1-3 years depending on the date printed on the package. This is because the drying process has removed most of the leaf's moisture, which slows down decay. Once opened, dry peppermint leaves can last for about 1-2 years if properly stored. Fresh peppermint leaves, however, have a much shorter lifespan. They typically last for about 1-2 weeks in the fridge. If you freeze fresh peppermint leaves, they can last for about 9-12 months.
How do you tell if peppermint leaf is bad?
With peppermint leaves, there are a few telltale signs to look out for to indicate spoilage. For fresh leaves, signs of spoilage include a change in color to brown or black, a wilted or slimy texture, and an unpleasant smell. For dried leaves, it's a little less straightforward. Spoilage will be more about a loss of potent aroma and flavor than visible signs. If your dried peppermint leaves don't have a strong fragrant smell when you open the container or if they have a stale taste, it might be time to replace them.
Tips for storing peppermint leaf to extend shelf life
• Store your fresh peppermint leaves in the refrigerator wrapped up in a slightly damp paper towel.
• To store dried peppermint leaves, use airtight containers and place them in a cool, dark and dry place.
• Freezing fresh peppermint leaves can further extend their shelf life. To freeze, wash and pat dry the leaves and then place them in a zip-lock freezer bag.
• If you have a large batch of fresh peppermint, you can dry them yourself. Simply hang the stems up in a dark and dry place, or dry them in a food dehydrator and store them in airtight containers.
