Why Is My Matcha Brown Or Yellow Instead Of Green?

One of the easiest ways to judge matcha quality is its colour. While colour alone doesn't determine quality, it can provide important clues about the origin, harvest and freshness of the matcha you're drinking.

If your matcha looks dull, yellow, or brown instead of vibrant green, there's a good chance you're drinking lower-quality matcha. Learn more in our guide to recognising high-quality matcha powder in Australia.

Here’s what your matcha colour is really telling you.

 

 

Brown or yellow matcha means old or low-grade leaves

Low-quality matcha is made from:

• Late-harvest tea leaves
• Leaves that weren’t shade-grown
• Powder that’s been sitting in warehouses too long

This causes oxidation, which turns matcha dull and brownish. Oxidised matcha tastes flat, bitter and weak, no matter how much you whisk it.

 

What Colour Should Good Matcha Be?

High-quality ceremonial matcha should have a vibrant green colour with a bright, fresh appearance.

This colour comes from the shading process used before harvest, which increases chlorophyll levels in the leaves. The youngest leaves, harvested in spring, typically produce the brightest green matcha and the smoothest flavour profile.

While colour isn't the only indicator of quality, it is often one of the first signs that a matcha has been carefully grown and processed.

 

 

Why Japanese Uji matcha is so green

The best matcha in the world comes from Uji, Japan, where tea plants are shaded before harvest. This increases chlorophyll, giving matcha its bright green colour and rich flavour.

The same factors that create a vibrant green colour also contribute to matcha's sweetness, smoothness and overall quality. Understanding these quality indicators can help you choose a better ceremonial matcha and avoid lower-grade alternatives.

Your matcha should look as good as it tastes

If your powder isn’t bright green, it won’t taste good either. Fresh, high-grade matcha should be:

• Smooth
• Creamy
• Naturally sweet
• Vibrant in colour

Anything dull is a shortcut.

If your matcha looks dull or yellow, it’s usually a sign of lower-grade leaves or oxidation.

Good matcha doesn’t need sugar or syrups to taste enjoyable, the quality speaks for itself.
