How to Identify High-Quality Matcha?

Is your matcha truly worth its price?

✔︎ Made in Japan
✔︎ Uji Matcha
✔︎ Organic

Do these labels alone make you think the matcha is high quality?

In fact, they are not enough to judge the true quality of matcha. Even among Uji matcha products, some cost only a few euros, while others cost several dozen euros for just 30g.

At the same time, a higher price does not always mean higher quality. Some products are priced higher because of branding or marketing.

So, what kind of matcha is truly worth choosing?

The answer lies in what kind of tea leaves are used and how the matcha is made.

In this article, we will explain the eight key factors you need to know to identify high-quality matcha.

Why Does the Price of Matcha Vary So Much?

Among all types of matcha, Uji Matcha, produced near Kyoto, is widely regarded as one of the highest-quality varieties in the world.

However, even products labeled as Uji Matcha can range in price from just a few euros to several dozen euros.

So, why is there such a large price difference?

The reason is simple: the label Uji Matcha alone does not tell you the quality of the matcha.

The harvest season, tea cultivar, harvesting method, milling process, and even how the tea leaves are blended all influence the flavor, aroma, color, and ultimately the price.

In other words, not all Uji Matcha is premium quality.

The eight most important factors that determine both the quality and the price of matcha are listed below.

1. Origin
2. Harvest Season
   
3. Harvesting Method
4. Cultivation Method
5. Milling Method
   
6. Organic vs. Conventional
7. The Expertise Behind Matcha Blending

Now, let's take a closer look at how each of these factors affects the quality of matcha.

1. Origin

The quality of matcha is greatly influenced by where the tea leaves are grown.

Japanese matcha is highly respected around the world, but not all Japanese matcha is of the same quality.

Climate, soil, water quality, sunlight, and the difference between daytime and nighttime temperatures all affect the flavor, aroma, and color of the tea.

Among Japan's tea-growing regions, Uji, Kyoto is especially well known for producing premium-quality matcha.

Uji has an ideal environment for growing high-quality tea. Cool nights, warm days, frequent morning mist, and well-drained soil allow tea leaves to grow slowly and develop rich umami and natural sweetness.

The morning mist also softens strong sunlight, helping the leaves remain tender rather than becoming tough.

Why Uji is Ideal for Matcha Cultivation

• Large day-night temperature difference
  ：Tea leaves grow slowly and develop more umami.
• Frequent morning mist
  ：Softens strong sunlight and reduces stress on the leaves.
• Well-drained soil
  ：Promotes healthy root growth and stable quality.
• Moderate humidity
  ：Helps the leaves remain soft and tender.
• Long history of tea cultivation
  ：Generations of expertise have refined cultivation techniques.

Tea plants used for matcha produce the best leaves when they grow in an environment with softened sunlight and balanced humidity, rather than under intense direct sunlight.

Around Uji, morning mist naturally reduces the intensity of sunlight reaching the tea fields. Combined with the area's large day-night temperature difference, the tea leaves grow more slowly and store higher levels of umami compounds. As a result, they develop the sweetness, rich umami, and vibrant green color that characterize high-quality matcha.

Why Uji Matcha Is Highly Valued

• Large day-night temperature differences help tea leaves develop rich umami.
• Morning mist softens strong sunlight, allowing the leaves to remain tender.
• Well-drained soil supports healthy tea plants and consistent quality.
• Centuries of tea-growing and processing expertise have been passed down through generations.
• Strict quality control helps produce premium-grade matcha.

For these reasons, Uji, Kyoto has earned its reputation as one of the world's finest matcha-producing regions. Its unique natural environment and long tradition of tea cultivation make it an ideal place for producing exceptional matcha.

That is why Matcha Lab carefully selects matcha grown in Uji, Kyoto, placing great importance on the origin of every tea leaf.

2. Harvest Season

One of the most important factors affecting matcha quality is when the tea leaves are harvested.

Tea leaves used for matcha are harvested several times a year, but their quality varies significantly depending on the harvest season.

The first harvest (First Flush), picked in spring, is considered the highest quality. During the winter months, the tea plants slowly store nutrients, resulting in leaves that are rich in theanine, the amino acid responsible for matcha's umami.

As a result, first-flush leaves have stronger sweetness, richer umami, a vibrant green color, and a more complex aroma.

As the season progresses to the second and third harvests, the leaves mature. Their catechin content increases, leading to more bitterness and astringency, while sweetness and umami gradually decrease.

These are general characteristics. Actual flavor and quality also depend on factors such as cultivar, shading period, cultivation methods, processing, and growing conditions.

3. Harvesting Method

One of the key factors that determines matcha quality is how the tea leaves are harvested.

High-quality matcha is made primarily from young, tender tea leaves that are rich in nutrients. Because of this, the quality of the harvested leaves has a major impact on the matcha's umami, aroma, and bitterness.

There are two main harvesting methods: hand-picking and machine harvesting.

Harvesting Method	Characteristics	Challenges
Hand-Picked	Young leaves only, delivering superior quality.	Time-consuming and expensive.
Machine Harvested	Fast and efficient for mass production.	Less consistent quality due to mature leaves.

With hand-picked matcha, experienced workers carefully select each tea leaf by hand, focusing on the youngest and most tender shoots. This helps produce matcha with rich umami and minimal bitterness or harshness.

In contrast, machine harvesting allows large quantities of tea leaves to be collected in a short time. While it is highly efficient, mature leaves and stems are more likely to be included, making it a method that prioritizes production efficiency.

Today, however, hand-picking is becoming increasingly rare due to labor shortages and the aging of Japan's tea farming community.

As a result, hand-picked matcha is valued not only for its exceptional quality but also for its limited production and rarity.

4. Cultivation Method

One of the most important steps in producing high-quality matcha is shade-growing.

Unlike regular green tea, the tea leaves used for matcha are grown using a unique cultivation method. About 20–30 days before harvest, the entire tea field is covered with black shade cloth to block direct sunlight. This process is known as shade-growing.

By reducing the amount of sunlight, the tea plants change the way they produce and store nutrients. As a result, the leaves develop the rich umami, natural sweetness, and vibrant green color that are characteristic of premium matcha.

Benefits of Shade-Growing

• Rich umami and sweetness
  ：Higher levels of theanine, the amino acid responsible for umami.
• Vibrant green color
  ：Increased production of chlorophyll, the pigment that gives matcha its vivid green color.
• Less bitterness and astringency
  ：Reduced production of catechins, the compounds responsible for bitterness.

As you can see, shade-growing is an essential process for creating the unique flavor and appearance of matcha.

However, covering and maintaining an entire tea field requires considerable time, labor, and cost. The longer the shading period, the more difficult it becomes to manage the tea plants, increasing production costs.

For this reason, premium-quality matcha is typically produced using carefully managed shade-growing techniques, and the additional effort is reflected in its price.

What is the definition of matcha?

To be legally classified as matcha, the tea must be made from tencha—tea leaves that have been shade-grown, steamed, and dried before being ground into powder.

In other words, shade-growing is not only essential for producing high-quality matcha, but also a fundamental step in producing matcha itself.

5. Milling Method

Matcha is made by grinding tencha (shade-grown tea leaves) into an ultra-fine powder.

However, even when the same tencha is used, the milling method can significantly affect the matcha's aroma, flavor, and color.

Today, there are two main milling methods: stone milling and high-speed grinding.

Milling Method	Characteristics	Challenges
Stone Milling	Preserves aroma, vibrant color, and delicate flavor through low-friction grinding.	Slow production and higher cost.
High-Speed Grinding	Enables fast, large-scale production.	Heat generated during grinding may reduce aroma and flavor.

A traditional stone mill can produce only about 30–40g of matcha per hour—roughly enough to fill a single 30g matcha tin.

Although this method is not suitable for mass production, the slow grinding process minimizes frictional heat, allowing the matcha to retain its natural aroma, vibrant green color, and delicate flavor.

In contrast, high-speed grinding is much more efficient and is widely used for large-scale production. However, the heat generated during grinding can affect the aroma and overall flavor of the finished matcha.

In recent years, the global matcha boom has caused demand to rise rapidly, while Japan's production capacity has struggled to keep up. As a result, more manufacturers have adopted high-speed grinding to increase production.

Because of this, stone-milled matcha is valued not only for its exceptional quality but also for its limited production and rarity.

6. Organic vs. Conventional

Organic matcha is often considered higher quality, but organic certification does not directly determine how good a matcha tastes.

The flavor and quality of matcha depend on many factors, including origin, harvest season, cultivar, shading, cultivation, processing, and blending.

The main value of organic matcha lies elsewhere: strict restrictions on the use of synthetic pesticides and fertilizers.

	Organic Matcha	Conventional Matcha
Main Value	Reduced use of synthetic pesticides and fertilizers	Greater cultivation flexibility
Impact on Flavor	Depends on cultivation and processing	Depends on cultivation and processing
Cultivation	Strictly regulated	More cultivation options
Harvest Yield	Generally lower	Generally higher
Price	Usually higher	Varies by quality

This can be particularly relevant for matcha because the entire tea leaf is ground into powder and consumed, rather than being steeped and removed like traditional loose-leaf tea.

Organic matcha is therefore a valuable choice for consumers who want to reduce their exposure to certain agricultural chemicals and care about how their tea is grown.

Ultimately, organic does not automatically mean better-tasting matcha. Its value lies in the cultivation standards, environmental considerations, and additional reassurance it can offer consumers.

7. The Expertise Behind Matcha Blending

The final quality of matcha is determined not only by the tea leaves themselves, but also by the expertise of the people who evaluate and blend them.

In Japan, experienced tea professionals use specialized sensory evaluation skills to assess characteristics such as color, aroma, flavor, umami, bitterness, and overall balance.

This expertise is especially important because matcha is rarely judged by a single factor. Origin, harvest season, cultivar, cultivation, and processing all influence the final result.

A skilled tea expert carefully evaluates different teas and combines them to create a specific flavor profile.

Key Elements in Matcha Blending

• Tea Cultivar: Balances umami, sweetness, aroma, and color.
  
• Harvest Season: Adjusts intensity, bitterness, and overall character.
  
• Origin: Adds regional characteristics and aroma.
  
• Sensory Evaluation: Determines how these elements work together.

This is why two products labeled Uji Matcha can taste completely different.

High-quality blending is not simply about mixing tea leaves. It requires trained sensory evaluation, experience, and a deep understanding of tea.

Is Cheap Matcha Really a Good Deal?

At first glance, inexpensive matcha may seem like a smart choice. However, there is always a reason why some matcha is cheaper than others.

Common Characteristics of Low-Price Matcha

• Uses a higher proportion of second- or third-flush tea
  ：Results in more bitterness and astringency.
• Includes more stems and mature leaves
  ：Produces a harsher, less refined taste.
• Ground using high-speed mills
  ：Aroma and flavor may become less vibrant.
• Prioritizes mass production
  ：Quality tends to be less consistent.
• Does not disclose the harvest season or tea cultivar
  ：Makes it more difficult to evaluate quality.

Of course, if you're making matcha lattes or desserts, a more affordable matcha can still be a good choice, especially when mixed with milk or other ingredients.

However, if you want to experience the natural sweetness, rich umami, delicate aroma, and vibrant green color of authentic matcha, choosing based on price alone is not recommended.

Buying very cheap matcha is a bit like buying stale coffee or wine that has lost its aroma.

You can still drink it—but you won't experience the qualities that make it truly enjoyable.

The same is true for matcha.

If your matcha is overly bitter, lacks aroma, and has a dull color, you may come away thinking that matcha simply isn't enjoyable.

That would be a shame!!

If you want to experience what matcha is truly meant to taste like, choose authentic Uji Matcha.

Have You Ever Experienced Authentic Matcha?

Authentic matcha is more than simply matcha labeled "Made in Japan" or "Uji Matcha."

True premium matcha is carefully crafted with attention to every detail—from its origin, harvest season, tea cultivar, harvesting method, cultivation method, milling process, to the blending technique.

These factors work together to create the rich umami, natural sweetness, delicate aroma, and vibrant green color that define exceptional matcha.

When Japanese matcha is sold overseas, its retail price includes not only the value of the tea itself, but also the costs of bringing it safely from Japan to your country, including:

• International shipping
• Import duties
• Value Added Tax (VAT)
• Local storage and distribution costs
• Exchange rate fluctuations

These costs are all reflected in the final retail price.

In other words, the price of Japanese matcha sold overseas is not simply a premium for the brand. It reflects both the value of high-quality tea leaves and the cost of delivering authentic Japanese matcha to customers around the world.

That's why it's important to look beyond the price tag. Instead of asking only whether a matcha is expensive or inexpensive, ask why it is priced that way.

At Matcha Lab, we carefully select premium matcha from Uji, Kyoto, and bring the authentic taste of Japan to customers around the world.
