How to store matcha.

Light, heat, air and moisture are what turn bright jade matcha dull. Where to keep it, how long it lasts, the fridge trap almost everyone falls into, and how to store the whisk too.

The short answer

Keep matcha sealed, cool and dark. Unopened, it keeps for up to about 18 months in a cool place or the fridge. Once opened, use it within about a month for the best colour and flavour. If you keep it in the fridge, let the sealed pack warm to room temperature before opening, or condensation forms inside and spoils the powder.

What you need to know

Enemy 1

Light

Breaks down chlorophyll, turning matcha from jade to khaki. Clear jars on a bench are the fastest way to ruin it.

Enemy 2

Heat

Speeds up every kind of staling. A pantry next to the oven, or a car in summer, does real damage.

Enemy 3

Oxygen

Dulls aroma and colour. Squeeze the air out of pouches and close tins firmly.

Enemy 4

Moisture

Makes matcha clump and lose its fresh flavour. Never use a wet spoon.

Matcha does not go off like milk. It has a best before date, not a use by date. Past its best it fades: less colour, less aroma, more bitterness. It is still safe to eat if it has been kept dry and shows no mould or off smell.

Signs your matcha is stale

  1. The colour has gone from jade to olive or yellowish.
  2. It smells flat, dusty or of hay rather than fresh and sweet.
  3. It tastes noticeably more bitter and less sweet than it did.
  4. It has clumped into hard lumps that do not break when sifted.

Using older matcha

Stale matcha is not unsafe, just less delicious. Use it in baking, smoothies or a strong latte, where sugar and milk cover the faded flavour. Our matcha pancakes and matcha tiramisu are good homes for it.

How to store a matcha whisk

  1. Rinse in warm water straight after use. No soap.
  2. Dry it on a holder, tines down, in open air.
  3. Never box it damp. In humid Australian summers that is how mould starts.
  4. Keep it away from the stove and direct sun, which dry and crack the bamboo.

Questions people ask

How should I store matcha powder?
Sealed, cool and dark, away from light, heat, air and moisture. A sealed pouch or tin in a cool pantry or the fridge works.
Should matcha be kept in the fridge?
It can be, especially in summer, but let the sealed pack come to room temperature before opening to avoid condensation.
Does matcha expire?
It has a best before date rather than a use by date. Past it, matcha loses colour and flavour but is not unsafe if kept dry.
How long does matcha last once opened?
About a month for the best colour and flavour, kept sealed between uses.
Can you freeze matcha?
Unopened packs, yes. Thaw fully before opening so condensation does not form inside.
How do you store a matcha whisk?
Rinse it, then dry it upright on a holder in open air. Never store it damp in a closed box.
