For drinking
Matcha for thin tea or daily matcha should be smooth, balanced, and pleasant to drink. Umami and bitterness should feel clean rather than harsh.

Why Sanrokuen Matcha?
Not just “green powder.” Matcha should have a story and a reason.
Matcha is loved worldwide, but not all matcha is made for the same purpose. A matcha for thin tea, a matcha latte, a dessert, or a café menu needs different balance in color, aroma, umami, bitterness, powder texture, and cost performance.
Sanrokuen is based in Kumamoto, Kyushu. We focus on practical Japanese matcha: matcha that is easy to use, stable enough for business, and supported by both local tea-making knowledge and component analysis.

A lesser-known old tea origin in Japan
Kumamoto tea has a deeper history than many people imagine.
The well-known story of Japanese tea often begins with Eisai, the founder of the Rinzai school of Zen Buddhism, who is said to have brought tea seeds back from Song China and planted them in the Seburi mountain area in 1191.
Yet Kumamoto also has an important early record. The Hirakawa family documents, a designated cultural property in Kumamoto, include the “Yoshimine Morotaka Shoryo Yuzurijo-an,” which is regarded as valuable evidence that tea was already being produced in a regional area at the end of the 12th century. Local tradition also refers to a record of 50 kin of tea being presented as tribute. This makes Kumamoto one of Japan’s lesser-known old tea-producing areas.
This page presents Kumamoto not simply as a “new matcha area,” but as a region where old tea culture, local farming, and modern quality analysis can meet.
Quality by component analysis
We check what cannot be seen by color alone.
Sanrokuen conducts component testing on all first-flush matcha lots and selected second-flush lots. Color and aroma matter, but we also want objective data that helps us understand the tea’s quality, suitability, and consistency. See our original comparison in First-Harvest vs Second-Harvest Matcha.
MoistureImportant for stability, storage, and freshness.
Total nitrogenA key indicator related to tea quality and richness.
Free amino acidsHelps evaluate umami and sweetness.
TheanineA major amino acid associated with matcha’s smooth umami.
FiberRelated to leaf maturity and texture.
TanninHelps understand astringency and bitterness.
CaffeineImportant for product information and balance.
Vitamin COne of the natural components in green tea.
AF ScoreA practical index for overall component evaluation.
Designed with Kumamoto farmers
From “good tea leaves” to planned matcha quality.
Kumamoto has a tea grading culture that includes certified teas such as five-star and three-star Kumamoto teas. Because component analysis is familiar to many local tea producers, it creates a practical foundation for designing better tea together.
1
Choose suitable varieties
We consider color, umami, aroma, and suitability for matcha, latte, and desserts.
2
Plan cultivation and harvest
Covering, harvest timing, and leaf condition are discussed with farmers to aim for higher-quality matcha.
3
Analyze and improve
Measured components help us compare lots, improve future production, and select the right use for each matcha.
How this planning continues before and after harvest
Our farmer-directed process includes producer selection, cultivar choice, agreed quality targets, full-volume purchase of commissioned tea, quality-based pricing, component testing and feedback to the next season.
Particle Size and Milling
Powder texture is designed for the intended use.
Matcha quality is not determined by raw material alone. Particle size affects smoothness, coarse-particle sensation, dispersion, foam, powder handling, and suitability for drinks or food products.
Using the same tea raw material, Sanrokuen measured cyclone-milled powder at a D50 of approximately 9.6–10.3 μm and ball-milled powder at 18.3 μm. The detailed page explains why the finer option is not automatically the best option for every buyer.
Original Tea Analysis
First-harvest vs second-harvest matcha: what our measurements found.
Sanrokuen compared five first-harvest tea lots with three second-harvest Saeakari lots. The first-harvest group showed higher average free amino acids and theanine, while the second-harvest group showed higher tannin and a stronger profile that can work well in lattes and desserts.
The article explains why our ceremonial-positioned matcha uses first-harvest material, why later harvests can be useful for milk-based drinks, and why we still make the final decision by tasting.
Choose matcha by use
For matcha latte
Latte matcha needs clear color, body, and enough flavor to remain present when mixed with milk or plant-based milk.
For desserts & baking
For cakes, chocolate, ice cream, and bakery products, color, aroma, powder texture, and cost performance are especially important.
For milk, soft serve and desserts, matcha is not the only Japanese option.
Sanrokuen also selects first-harvest shaded tamaryokucha and other Japanese leaf teas specifically for powder use. In our own shop, repeated testing showed that leaf-tea powder produced a clearer and more satisfying tea flavor than matcha in Chiran tea soft serve. We have continued selling that formula for 14 years.
What actually makes matcha different from green tea powder?
In Japan, matcha begins with tencha that is shaded, steamed and dried without rolling. Simplified tencha is also unrolled, while sencha, gyokuro and tamaryokucha are rolled and remain green tea powder after milling. These are useful processing categories—not an automatic ranking of flavor.

FAQ
Common questions about Sanrokuen matcha
Matcha selection depends on the actual use. Please contact us if you need help choosing a grade or a business-use product.
Is Kumamoto matcha well known overseas?
Not yet. That is exactly why we believe it has potential. Kumamoto has a long tea history and strong local tea production, but its matcha story is still less known than Kyoto or Uji. This gives business customers a more distinctive origin story.
Do you offer matcha for lattes and desserts?
Yes. Sanrokuen handles matcha for drinking, matcha latte, sweets, baking, food service, and business use. The best option depends on color, flavor strength, bitterness, powder texture, and price range.
Can overseas customers buy Sanrokuen matcha?
Overseas availability depends on destination, quantity, shipping method, and food import regulations. Please contact us in English with your country, desired product, quantity, and intended use.
Why do component tests matter?
Component analysis helps evaluate quality beyond appearance. Total nitrogen, free amino acids, theanine, fiber, tannin, caffeine, vitamin C, moisture, and AF score help us understand taste, suitability, and lot consistency.
