Does Matcha Powder Expire? Shelf Life, Storage & Freshness Guide
If you’re wondering “does matcha powder expire?”, the answer is yes—but not in the way most foods do. Matcha doesn’t suddenly go bad; instead, it slowly loses colour, flavour, and nutritional value over time.
Here’s what you need to know to keep your matcha fresh and worth drinking.
1. How Long Does Matcha Powder Last?
🍵Unopened Matcha
- 6–12 months from production
- Shelf life depends on quality, harvest, and packaging
🍵Opened Matcha
- Best consumed within 1–3 months
- Can last up to 6 months if stored perfectly
*High-quality matcha actually expires faster because it contains more delicate antioxidants.
2. What Happens When Matcha Expires?
Expired matcha is usually not unsafe, but quality drops quickly:
- Bright green turns dull or yellowish
- Fresh, umami flavour becomes bitter or flat
- Antioxidant levels decrease
*If your matcha no longer tastes fresh, it’s past its prime.
3. How to Tell If Matcha Has Gone Bad
Check three things:
- Colour – Fresh matcha is vibrant green
- Smell – Should be grassy and lightly sweet, not dusty
- Taste – Old matcha tastes harsh or chalky
*If it fails these tests, it’s time to replace it.
4. Can You Still Use Expired Matcha?
As long as there’s no mould or moisture, expired matcha is usually safe—but better used for:
- Baking
- Smoothies
- Matcha lattes
For drinking straight, fresh matcha makes a huge difference.
5. How to Store Matcha Properly
To extend matcha’s shelf life:
- Store in an airtight, light-proof container
- Keep away from heat, air, and moisture
- Refrigerate only if fully sealed
