No, black pepper doesn't technically expire in the sense that it becomes unsafe to consume. However, it does lose its potency and flavor over time. The length of time it retains its best quality depends on whether it's whole peppercorns or ground pepper, and how it's stored.

Regardless of whether it's whole or ground, commercially packaged black pepper does not spoil but loses its potency over time. [Source: Still Tasty, Reddit r/Frugal] This means the flavor will become weaker and less intense, not that it will become unsafe to eat.
Factors Affecting Shelf Life
Proper storage significantly impacts the shelf life of black pepper. Storing it in a cool, dark, and dry place in an airtight container helps preserve its flavor and potency. Exposure to light, air, and moisture accelerates the loss of flavor.
When to Replace Your Black Pepper
While black pepper won't make you sick, it's best to replace it when its flavor noticeably diminishes. A simple sniff test can help determine if your pepper is still potent. If the aroma is weak, it's time for a fresh batch.
