If you've ever seen two packs of matcha powder next to each other, you might have noticed a distinct color difference: one is bright emerald green, the other is more yellow or brown.

But is this just a cosmetic difference? Or does color truly indicate the quality of matcha?

In this article, we'll learn about the importance of matcha color , how it's formed, and what it can tell you about its quality, taste, nutritional value, and even cultivation method. After reading, you'll be able to distinguish high-quality matcha from low-quality, just by looking at it!


What makes matcha green?

The bright green color of matcha comes from a natural compound called chlorophyll , the same pigment that gives the leaves their green color.

The more chlorophyll in the leaves, the more intense the green color in the matcha, which often indicates:

  • Shade growing of leaves (a Japanese technique for quality improvement)
  • Harvesting leaves in the spring season
  • Use the young, tender leaves from the top of the plant.
  • Lack of oxidation during processing

Color shades and their meanings

1. Emerald Green (Celebration Grade)

  • Color: Bright, vibrant green
  • Meaning: Highest quality, smooth, umami-rich taste
  • Use: Pure drinking without additives

2. Light green or olive (luxury grade)

  • Color: Good green but less bright
  • Meaning: High quality, but less festive
  • Use: Suitable for matcha latte or daily drinking

3. Yellowish green or brown (cooking grade)

  • Color: pale or yellowish
  • Significance: Low quality, larger leaves or late season
  • Use: For cooking or desserts

Why is bad matcha not bright green?

Pale or yellow color in matcha is often due to:

  • Do not use shading during planting.
  • Harvest from the lower leaves or late in the year.
  • imprecise drying or grinding processes
  • Oxidation due to poor storage
❌ If you find your matcha turning brown, it has likely lost a significant portion of its nutritional value.

Does color affect taste?

Yes, directly.

  • Bright green matcha: Smooth, slightly sweet, and rich in umami
  • Pale matcha: Tastes too bitter or grassy, lacking clarity and depth

The reason? Young, theanine-rich leaves give a balanced flavor, while older or oxidized leaves increase the bitter taste.


When is color not enough to judge?

Although color is a powerful indicator, it alone is not sufficient to determine quality. Other factors must be considered, such as:

  • Consistency : Is it fine like powder? Or rough?
  • Smell : Herbaceous and aromatic or faint and weak?
  • Country of Origin : Are you from Japan? From which region?
  • Harvest and packing date : The newer, the better.
  • Packaging Type : Is it protected from light and air?


Conclusion

The color of matcha isn't just a matter of aesthetics—it's a true indicator of its quality and nutritional value . If you see a vivid emerald green color, you're dealing with carefully produced matcha. If the color is dull or brownish, you may want to reconsider your purchase.
