"How long does tea last" has no single number because tea fades rather than expires, and the timeline depends entirely on type, format and storage. Here is the short version. This sits beside does tea expire in the storage cluster.
What the date on the packet means
The printed date on tea is a best before, a quality estimate, not a safety use by. Dry tea kept dry does not become unsafe on that date; it is the manufacturer guessing when peak character has faded. Treat it as guidance, not a deadline, see does tea go off.
The timeline by type
Stored well, opaque, airtight, cool, dark, dry, rough working life: green and white tea are at their best within roughly 6 to 12 months because delicate teas fade fastest; black tea and firm oolong hold character well for around 1 to 2 years; pu erh and dark teas are the exception that can improve with age. Flavoured teas track the shortest end because added oils fade first.
Format changes the clock
Whole loose leaf lasts longest; fine bagged tea stales faster once the box is opened; individually foil wrapped bags sit in between. An unopened, well sealed pack always outlasts an opened one, see storing loose leaf tea.
How to tell it is past it
Faded tea looks dull, smells of little, and brews flat and characterless, that is stale, not unsafe, and still drinkable if uninspiring. The bin test is different: any sign of damp, mould, musty or off smell, or clumping means moisture got in, and that one goes straight out, see can old tea make you sick.
Stretching the life
You do not extend tea by freezing your daily caddy; you extend it by buying sensible amounts, decanting into airtight opaque tins, and keeping them cool, dark and away from smells, see how to keep tea fresh. Freshness is a storage habit, not a heroic intervention.
What it boils down to
Roughly: delicate teas months, robust teas a year or two, dark teas longer, all of it safe while dry and only ruined by damp. The date is a quality hint, your nose and eyes are the real test, see can you drink old tea.
Shelf life by type, at a glance
| Tea | Best window (stored well) |
|---|---|
| Green & white | Best within ~6 to 12 months; fade fastest |
| Oolong | ~1 to 2 years; lighter oolongs fade sooner |
| Black | ~2 years comfortably; very forgiving |
| Pu-erh & dark | Years, can improve with proper ageing |
| Herbal infusions | ~1 to 2 years; aroma is the first thing lost |
| Tea bags vs loose | Bags (smaller particles) stale faster than whole loose leaf |
