Does Tea expire?
Does Tea expire?
It goes stale rather than off. Black tea holds up for years; green tea fades within a year.
Black: 2-3 years. Green and white: 6-12 months for good flavour
Tea is a dried leaf and is microbiologically stable, so old tea is safe tea. Oxidation and the loss of volatile compounds are what change it, and the less oxidised the tea was to begin with, the more it has to lose — which is why green tea goes flat and hay-like within a year while a robust black tea is much the same after three. Tea also picks up smells readily, so a tin stored next to coffee or spices tastes of them. Damp is the only thing that makes tea genuinely unusable, because mould can grow on wet leaf.
How to store it
- Airtight, opaque, cool, and away from anything aromatic.
- Do not refrigerate loose tea; condensation on opening is worse than the warmth.
How to tell it has gone
- A flat, papery or hay-like brew means the aromatics have gone.
- Any musty smell means damp and the tea should go.
"Use by" and "best before" are legally different. Use-by is a safety date and should be respected; best-before is about quality, and food is usually fine well past it. Where the two diverge matters, the page above says which applies.
