Hi Pamela,
Garli Ghetti has a shelf life of approximately 2 years depending on how you store it. You typically want to store dry spices in a dark, room temperature and dry area. If it is darker, it could be because it it being exposed to sunlight or absorbing moisture if it is near a stove. Should still be good though. Please let me know if you have any further questions or concerns. Thank you very much for your time and patronage!
