How to Store Loose-Leaf Tea to Keep It Fresh

The four things to keep out

Loose-leaf tea doesn't spoil in the way food does, but its aromatic oils fade with exposure. The faster that happens, the sooner a blend tastes flat rather than fragrant.

• ·Light — fades colour and breaks down aromatic compounds; store away from a sunny windowsill or countertop.
• ·Air — every opening lets aroma escape; reseal the pouch fully and press out excess air each time.
• ·Moisture — dried botanicals draw in humidity readily, which dulls flavour and risks mould; keep away from the kettle and steam.
• ·Heat — warmth accelerates the loss of aromatic oils; a cupboard is better than anywhere near a hob or oven.

Where to keep it

A cool, dark cupboard is usually the best place in an ordinary kitchen — better than a shelf near a window or above the stove. If you decant into a separate container, choose an opaque, airtight one over a clear glass jar.

The original pouch is designed to protect the blend, so if you do decant it, keep the pouch resealed as a backup rather than discarding it.

How long an opened pouch stays at its best

Stored well, whole-leaf herbal tea typically holds its aroma for six to twelve months after opening, though it remains safe to drink well beyond that — it simply grows quieter over time rather than turning.

A blend heavy in flowers and soft leaves (chamomile, lemon balm) tends to fade faster than one built on roots, barks and seeds (liquorice, ginger, fennel), which hold their character longer.

Signs a blend has faded

Fading shows up as a duller aroma when you open the pouch, and a thinner, less expressive cup even with a full measure and a proper steep. That's a sign to use it up soon rather than a sign it's unsafe.
