“Ceremonial grade”
A market term does not tell you cultivar, farm, harvest, tencha process or actual sensory quality.
How to Find Good Matcha: A Tea Sommelier’s Sourcing Guide
KTeaShop · Tea Sommelier Sourcing Guide
How to Find
Good Matcha.
Go beyond “ceremonial grade,” colour and price. Learn how a Tea Sommelier follows matcha from cultivar and field to tencha, milling and the final cup.
Start with the frameworkThe starting point
Start with identity.
Then test the story.
A beautiful green powder tells me very little until I know what tea it is, where the leaf grew and how it became tencha.
When I source matcha, I do not search for one magic sign of quality. I build a picture from multiple variables, then test that picture through tasting and preparation.
What am I actually buying?
Cultivar → growing place → harvest → shading → tencha process → refinement → milling → storage → cup.
Before you buy
Four labels that can mislead you when used alone.
These words may contain useful information, but none of them can prove quality by itself.
Bright green
Colour matters, but cultivar, shading, freshness, lighting and photography all influence what you see.
First harvest
Spring material can be excellent, but poor cultivation or processing does not become excellent because it is first harvest.
Uji Kyoto
Uji, Kyoto is famous for matcha, but region is not a quality grade. Understanding terroir helps explain why matcha tastes different.
Matcha sensory quality framework
Eight variables to investigate.
Each block answers a different question. On mobile, treat them one at a time rather than trying to judge everything from one label.
01
Cultivar
Which genetic variety of the tea plant is being used?
02
Region & Terroir
Where did the leaf grow, and what environmental conditions shaped it?
03
Season
When was the leaf harvested, and how mature was the material?
04
Processing
How were shading, steaming, drying, refining and milling handled?
05
Blend
Single cultivar or intentional blend? What sensory target is being built?
06
Preparation
How does the tea respond to ratio, temperature and whisking?
07
Water
Does mineral composition reveal, flatten or distort the tea?
08
Vessel
How do bowl shape, heat and service change the drinking experience?
01 · Cultivar
What is a tea cultivar?
A cultivar is a selected variety of Camellia sinensis maintained for particular traits such as growth, harvest timing, colour, aroma or cup character.
Same species. Different genetic character.
Think of apples. Fuji, Gala and Granny Smith are all apples, but they are not identical. Tea works in a similar way. Yabukita, Okumidori, Saemidori, Samidori, Gokou and Asahi all belong to the tea plant species, but each cultivar has different inherited traits.
SpeciesCamellia sinensis
CultivarOkumidori
Finished teaMatcha
Japan has far more than nine tea cultivars.
Japan has well over one hundred recognised tea cultivars and breeding lines. Only a smaller group appears frequently in tencha and matcha production. So “Japanese tea cultivars” and “matcha cultivars” are not the same list.
Yabukita
Japan-wide benchmark cultivar used across many green-tea styles.
Okumidori
Often valued in covered tea for colour, roundness and softer expression.
Saemidori
Important in Kyushu; often associated with sweetness and vivid colour.
Samidori
Historic Kyoto cultivar closely associated with covered tea and tencha.
Gokou
Important Kyoto covered-tea cultivar, particularly associated with Gyokuro; also encountered in Matcha.
Asahi
Kyoto cultivar with a strong historical and quality association with Tencha.
Ujihikari
Kyoto cultivar valued for distinctive aroma and premium covered-tea quality.
Tsuyuhikari
Often discussed for vivid colour and aromatic character.
Yutakamidori
Major southern Japanese cultivar, especially important in Kagoshima.
Kanayamidori
Used in several Japanese green-tea styles and sometimes covered tea.
Sakimidori
A major Kyoto cultivar used in high-quality covered tea and Tencha.
Seimei
A newer Japanese cultivar developed for covered cultivation, Matcha and powdered tea.
Cultivar is the beginning of the investigation — not the answer.
Seeing “Okumidori” or “Gokou” on a package gives me a hypothesis. Region, terroir, cultivation, shading, harvest, tencha processing, blending and storage decide how that potential is expressed.
Cultivar→Terroir→Farming→Leaf→Processing→Cup
02 · Region & terroir
Same cultivar.
Different expression.
Region names matter, but I want the actual growing location and environment behind the name.
Yame
A regional label becomes useful when it connects to real field conditions, cultivation and a specific producer rather than acting as a prestige word alone.
Compare the place
Climate, elevation, rainfall, soil, sunlight exposure and farm management can change how the same cultivar develops.
Region→Climate→Field→Shading→Harvest
03 · Tea type
Cultivar is not tea type.
The same cultivar can be made into different teas. Cultivation and primary processing determine the finished form.
Rolled leaf tea
Sencha
Usually unshaded or lightly shaded. Steamed, rolled and dried.
Covered + rolled
Gyokuro
Shaded before harvest, then steamed, rolled and dried.
Matcha raw material
Tencha
Shaded, steamed and dried without the sencha-style rolling sequence.
Finished powder
Matcha
Refined tencha is milled into the fine powdered tea we drink.
Simple example
Okumidori = cultivar · Tencha = processed leaf material · Matcha = finely milled finished tea.
04 · Processing
Follow the leaf to the mill.
“Stone-ground” is only one part of the chain. Good matcha is built before the powder appears.
From shading to storage
For sourcing, I want to understand what happened at every critical stage rather than relying on one attractive production claim.
01
ShadeHow and how long was the field shaded?
02
HarvestWhen was the leaf picked and how mature was it?
03
SteamHeat stops oxidation and sets the direction of the green-tea character.
04
Dry as tenchaThe leaf is dried without sencha-style rolling.
05
RefineStems, veins and unwanted material are separated before milling.
06
Mill & storeMilling date, temperature exposure and storage affect the final powder.
05 · Sensory evaluation
Then I taste.
The information gives me a hypothesis. The cup tells me whether the hypothesis makes sense.
Aroma
Clarity, freshness, depth and persistence.
Sweetness
Natural sweetness and how it integrates with the rest of the cup.
Umami
Depth and savoury quality, not maximum intensity at any cost.
Bitterness
Structure versus harsh, dominating bitterness.
Astringency
Drying sensation, roughness and how long it lingers.
Texture & finish
Density, smoothness, after-aroma and length.
Preparation response
I test temperature, ratio, water and whisking. A tea that only works in one perfect condition may not suit café or hospitality service.
Vessel response
The vessel does not change the cultivar, but shape, heat retention and drinking geometry can change perception and service.
06 · Professional sourcing questions
What I ask a producer.
Traceability becomes part of quality when you source professionally.
01What cultivar or cultivars?
02Single cultivar or blend?
03Where was the leaf actually grown?
04What harvest period and year?
05How and how long was it shaded?
06Who produced the tencha?
07Where was the tencha refined?
08When was the finished tea milled?
09How was it stored before and after milling?
10Can the lot be traced?
11What annual quantity is available?
12Can the sensory profile be reproduced next lot?

The sourcing framework becomes easier to understand when teas are compared side by side. In Zürich, KTeaShop uses comparative tasting to explore cultivar, processing and preparation in the cup.
