How to Store Matcha Properly: Keep Your Green Gold Fresh

Matcha is a delicate tea powder — vibrant, aromatic, and rich in antioxidants. But it’s also sensitive. Light, heat, air, and moisture can all dull its colour and flavour. Knowing how to store matcha properly ensures every cup stays bright, smooth, and full of life.

1. Keep It Cool and Dry

Once opened, matcha should be stored in a cool, dry place, away from direct sunlight and humidity. A dark cupboard or pantry is perfect. Avoid keeping it near the stove or window, where heat can quickly degrade its freshness.

2. Use an Airtight Container

Oxygen is matcha’s biggest enemy. After each use, seal your tea in an airtight container to minimise air exposure. Many matcha tins come with inner lids — if yours doesn’t, transfer it to a small, sealable jar. The tighter the seal, the longer the freshness.

3. Refrigerate for Longevity

For longer-term storage, especially in warm climates, store your matcha in the refrigerator. Just make sure it’s sealed tightly to prevent condensation or odours from affecting the powder. When using it, let the tin come to room temperature before opening to avoid moisture clumping.

4. Use It Within a Few Months

Once opened, it’s best to finish your matcha within one to three months. Over time, its vibrant green hue will fade, and the flavour can turn slightly bitter or flat.

The Takeaway

Proper storage is key to preserving the quality and health benefits of your matcha. Treat it like a fresh ingredient — keep it cool, dark, and airtight — and you’ll enjoy every cup as if it were just whisked in a Kyoto teahouse.
