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.

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.
