how long should you keep spices?
Stored in an airtight container, in a cool, dry place, spices retain their potency longer than you'd think â as long as 4 years for whole spices, 2 to 3 years for ground spices, and 1 to 3 years for leafy herbs, depending on the herb. Whole peppercorns, nutmegs and cinnamon sticks hold on to their flavor for ages.
