Can You Use Tea Bags After the Best-Before Date?
Written by Jordan Morley · Reviewed against FSA date labelling guidance · Last updated 28 October 2026
Yes. Tea bags have a best-before date, which is about quality rather than safety, so them is usually fine to use after the date. Check that they look and smell normal.
Why it's usually fine past the date
A best-before date is the maker's estimate of how long tea bags stays at its best. After it, the flavour fades; it doesn't suddenly become unsafe. The FSA says food is generally safe to eat after its best-before date, and using your own judgement also cuts food waste. Throw it away if you see: damp, mould or a musty smell.

Common questions
Do tea bags expire?
Not in a harmful way. The leaves lose flavour over time, so the tea tastes weaker. Keep them dry and away from strong smells.
How can I tell if tea bags has gone off?
Look for damp, mould or a musty smell. If none of those apply and it looks, smells and tastes normal, it is fine.
What actually changes after the best-before date?
The flavour fades. That's a drop in quality, not a safety problem (FSA).
What is the difference between use-by and best-before?
Use-by is about safety: do not eat after it. Best-before is about quality: the food is often fine after it, just past its best. Check which one is on your label.
