What Is Umami in Matcha? Why Japanese Matcha Is Known for Its Rich, Smooth Taste
Many people expect matcha to taste bitter.
After all, it comes from green tea leaves.
Yet one of the most surprising things about high-quality Japanese matcha is not its bitterness, but its umami.
Premium matcha is often described as smooth, mellow, rich, and naturally sweet. This unique depth of flavour is one of the reasons authentic Japanese matcha has become so highly valued around the world.
But what exactly is umami? Why does matcha have it? And is more umami always better?Let's take a closer look.
What Is Umami?
Umami is often referred to as the fifth basic taste, alongside sweet, salty, sour, and bitter.
The word itself comes from Japan and has been adopted into English without translation.
Unlike sweetness or bitterness, umami is difficult to describe. It's often experienced as:
- A savoury depth
- Lingering richness
- A full-bodied mouthfeel
- A satisfying, rounded flavour
Foods naturally rich in umami include kombu (kelp), miso, soy sauce, mushrooms, and aged cheeses.
High-quality matcha shares many of these same characteristics.
What Does Umami Taste Like in Matcha?
When people try premium matcha for the first time, they're often surprised.
"It's much smoother than I expected."
"It has a natural sweetness."
"It doesn't taste as bitter as I thought."
That's because great matcha isn't defined by bitterness alone.
Instead, it offers a harmonious balance of:
- Umami
- Gentle sweetness
- Fresh vegetal notes
- Mild bitterness
- A clean, lingering finish
The best matcha creates complexity rather than intensity.
Where Does Matcha's Umami Come From?
The primary source of matcha's umami is an amino acid called L-theanine.
L-theanine is produced in the roots of the tea plant and transported to the leaves.
When tea plants receive full sunlight, some of this amino acid is converted into catechins, compounds that contribute bitterness and astringency.
To preserve more L-theanine, tea plants intended for matcha are shaded before harvest.
This traditional cultivation method, known as shade growing, reduces sunlight exposure and allows more amino acids to remain in the leaves.
The result is the smooth, rich character that premium matcha is known for.
Shade growing is only one part of the story, however. Harvest timing, leaf selection, processing, and craftsmanship all contribute to the final flavour.

Why Has Japanese Matcha Traditionally Pursued Umami?
The flavour of matcha did not develop by accident.
For generations, Japanese tea producers have refined cultivation techniques to create teas with greater depth and balance.
These techniques include:
- Shade growing
- Careful nutrient management
- Cultivar selection
- Harvest timing
- Precise processing methods
Nitrogen plays an important role in the production of amino acids within tea plants. Some conventional tea farms use nitrogen-rich fertilisation strategies to encourage amino acid development, which can contribute to a deeper umami profile.
This is one reason why premium Japanese matcha often tastes noticeably richer than ordinary green tea.
However, flavour is influenced by many factors working together, not by fertilisation alone.
Is More Umami Always Better?
Not necessarily.
Historically, strong umami has often been associated with premium tea.
Today, many tea lovers believe that balance is even more important than intensity.
Just as wine and coffee enthusiasts appreciate different styles, matcha drinkers may prefer different expressions of:
- Umami
- Sweetness
- Aroma
- Freshness
- Gentle bitterness
The finest matcha isn't simply the one with the strongest umami.
It's the one where every element works together in harmony.
Organic Matcha and Umami
Organic matcha can absolutely have umami.
However, organic cultivation often follows a different philosophy from simply maximising a single flavour characteristic.
Some conventional tea farms may use nitrogen-rich fertilisation strategies to encourage amino acid production and create a more intense umami profile. By contrast, JAS-certified organic farming follows strict standards for soil management and permitted inputs, focusing on sustainable cultivation and the long-term health of the growing environment.
Because flavour is influenced by many factors—including cultivar, shading, harvest timing, soil management, and fertilisation—organic matcha can express umami in different ways.
Rather than pursuing intensity alone, many organic producers value harmony, clarity, freshness, and balance in the cup.
At More More Matcha, our matcha is JAS-certified organic. We believe great matcha isn't defined by the strongest umami, but by the natural balance between sweetness, aroma, freshness, and gentle savoury depth.

Does First Harvest Matter?
Yes.
Many ceremonial-grade matcha teas are produced from carefully selected first harvest leaves, which are generally more tender and naturally rich in desirable flavour compounds.
Combined with proper shading and careful processing, first harvest leaves help create the smooth, balanced character associated with premium matcha.

How to Experience Matcha's Umami at Home
Preparation makes a difference.
Water that is too hot can emphasise bitterness and mask the tea's natural sweetness and umami.
For ceremonial-grade matcha, water around 70–80°C (158–176°F) generally produces a smoother and more balanced cup.
Whisking technique also contributes to texture and overall enjoyment.

Beyond the Bitterness
Umami is one of the defining characteristics of authentic Japanese matcha.
It reflects centuries of cultivation knowledge, thoughtful farming practices, and an appreciation for flavour that goes beyond simple bitterness or sweetness.
At the same time, umami is only one part of the story.
The most enjoyable matcha combines richness, aroma, freshness, sweetness, and gentle bitterness into a harmonious whole.
The next time you prepare a bowl of matcha, take a moment to notice the subtle depth that lingers after each sip.
That quiet complexity is what the Japanese call umami.
