Yes, tea does expire, but the timeframe depends on several factors. While it won't become inherently unsafe to drink after its "best by" date (unless contaminated), its flavor and aroma will degrade over time.
How Long Does Tea Last?
According to tea expert Tony Gebely, author of Tea: A User's Guide, most tea lasts one to two years when stored correctly.

Factors Affecting Tea's Shelf Life:
- Type of tea: Different teas have different shelf lives.
- Storage conditions: Heat, light, and moisture significantly accelerate the degradation of tea's flavor and aroma. Proper storage in an airtight container in a cool, dark, and dry place is crucial. Source: Quora
- Freshness of tea: The initial quality and freshness of the tea leaves affect how long they retain their optimal flavor.
Is Expired Tea Safe to Drink?
While the flavor might diminish, properly stored tea that's past its best-by date isn't usually harmful. However, if you notice any mold, insect infestation, or off-putting odors, discard the tea. Source: Reddit
"Best By" vs. "Expiration Date":
Many tea bags have a "best by" date, indicating when the tea will be at its peak flavor and quality. This isn't a strict expiration date signifying it's unsafe to consume after. Source: Quora
