Matcha is delicate. Unlike loose-leaf tea, it’s a finely ground powder that has a much larger surface area, which means it’s especially sensitive to its environment. Proper storage protects matcha’s colour, aroma, and flavour — and ensures every bowl tastes as intended.
The Four Things Matcha Dislikes Most
To store matcha well, it helps to understand what causes it to degrade. Matcha is sensitive to:
- Air (oxygen) – leads to oxidation and flavour loss
- Light – especially sunlight, which dulls matcha's green colour
- Heat – accelerates ageing and bitterness
- Moisture – causes clumping and spoilage
Good storage simply means minimising exposure to these four elements.
The Best Way to Store Matcha at Home
1. Keep It Airtight
Store matcha in a tightly sealed cannister. Once opened, always close the lid promptly after use to limit contact with air.
If your matcha comes with a stand-up pouch, make sure you've sealed the press-to-close zipper fully. We would recommend to transfer the matcha from pouches into a can as it is easier to handle and has a better airtight lid.
It may be tempting to throw the desiccant in the bin as it can get in the way of scooping your matcha, but do bear with it as it's job is to absorb oxygen away from the matcha powder.
2. Store It in a Cool, Dark Place
A cupboard away from heat sources is ideal. Avoid storing matcha near ovens, kettles, or sunny windows.
Light — even indirect light — can slowly degrade matcha’s vibrant green colour.
3. Refrigeration: When It Makes Sense
Refrigeration can be helpful if you don’t consume matcha often, as cooler temperatures slow oxidation.
If you refrigerate matcha:
- Keep it fully sealed and airtight
- Allow it to return to room temperature before opening to prevent condensation
- Avoid repeatedly moving it in and out of the fridge
- Place the matcha deeper in the fridge away from the fridge door
For frequent daily use, room-temperature storage in a cool, dark place is often more practical and perfectly acceptable.
For longer term storage of unopened matcha, you may use the freezer.
What to Avoid ❌
- Leaving matcha exposed on the counter
- Storing it in clear or loosely closed containers
- Keeping it near steam, heat, or strong smells
- Opening cold matcha immediately after taking it out from the fridge
Matcha easily absorbs odours, so avoid storing it near spices, coffee, or scented products.
Why Matcha Changes Over Time
Even with good storage, matcha will slowly change. You may notice:
- Colour shifting from bright green to a softer olive tone
- Aroma becoming less fresh
- Flavour losing sweetness and gaining bitterness
This is natural oxidation, not a sign that the matcha is unsafe — simply less fresh.
For the best experience, matcha is ideally enjoyed within a few weeks to a couple of months after opening, depending on storage and frequency of use.
A Note on Freshness
Unlike certain loose leaf teas that can be aged, Matcha isn’t meant to be stored for long periods. In Japanese tea practice, freshness is valued, and matcha is treated as something to be enjoyed in its prime rather than preserved for later.
Good storage helps honour the work that went into producing it — from shading the tea plants to stone-grinding the leaves.
In Short
- Store matcha in airtight cannisters
- Keep it cool, dark, and dry
- Refrigerate only if needed — and avoid condensation
- Enjoy it while it’s fresh
A little care goes a long way toward a better bowl of matcha.
