What Is Tencha? The Raw Material Behind Matcha
Before matcha becomes a fine green powder, it exists as Tencha — the dried, shade-grown, deveined tea leaf that carries much of the quality potential of the final product.
Tencha (碾茶) is the intermediate tea material that becomes matcha after aging and grinding. It is steamed, dried, and deveined — but unlike sencha, it is not rolled.
Tencha vs. Sencha: The Key Difference
Tencha and sencha are both Japanese-style steamed green teas made from Camellia sinensis, but their cultivation and processing paths diverge in ways that matter commercially.
| Dimension | Tencha | Sencha |
|---|---|---|
| Growing condition | Shade-grown for weeks before harvest | Typically grown in full or partial sun |
| Rolling | Not rolled | Rolled into a needle-like shape |
| Leaf structure | Dried flat and brittle | Processed for direct infusion |
| Typical use | Aged and ground into matcha | Brewed as loose-leaf green tea |
| Flavor when steeped | Lighter and more delicate | More readily extracted when brewed |
The difference that matters most is rolling. Sencha is rolled after steaming, which helps break down cell structure and makes flavor easier to release during brewing. Tencha skips that step because it is designed to be ground into powder later rather than consumed as a conventional loose-leaf tea. [1]
How Tencha Is Made
The production process preserves a flat, brittle leaf structure that is suitable for later sorting, aging, and grinding.

Why Tencha Determines Matcha Quality
The source article makes a strong point: much of a matcha’s final quality is already determined before grinding begins.
Cultivar
The plant material itself shapes the chemical and sensory potential of the leaf.
- Flavor potential
- Amino-acid profile
- Color potential
Shading
Shading duration and intensity influence the raw material before harvest.
- Chlorophyll
- L-theanine
- Sweetness and umami balance
Harvest & Sorting
Harvest timing and careful removal of stems and veins affect the quality of the Tencha sent to grinding.
- Leaf tenderness
- Uniformity
- Raw-material cleanliness
Can You Drink Tencha as Tea?
Technically, yes — but it is uncommon. Because Tencha skips the rolling step, it does not release flavor into water in the same way as a tea designed for direct infusion.
What Buyers Should Ask About a Supplier’s Tencha
If Tencha quality effectively caps the quality of the finished matcha, supplier evaluation should begin before the milling stage.
| Question | Why it matters |
|---|---|
| Do you grow or source your own Tencha? | Helps clarify how much visibility the supplier has into origin and raw-material control. |
| Which regions and cultivars does it come from? | Origin and cultivar can influence sensory and processing characteristics. |
| How is it deveined and sorted? | Shows how stems, veins, and tender leaf material are handled. |
| How long is it aged? | Important if the supplier positions aging as part of flavor development. |
| Can you trace it back to the growing base? | Traceability makes supplier claims easier to evaluate. |
Our Approach: Control the Story Before Grinding
At VG Matcha, the source article describes control from the Tencha stage onward rather than buying finished Tencha from unknown third parties.
Tea Garden Network
Shade-grown leaf is sourced across a network of 8 tea garden bases.
- Known origin
- Regional sourcing
- Raw-material visibility
Minimum Six-Month Aging
Every batch of Tencha is aged for a minimum of six months before grinding.
- Controlled storage
- Flavor development
- Batch planning
Own Grinding Facility
Grinding is completed at VG Matcha’s facility in Anhui.
- Process control
- Traceability
- Commercial-scale consistency
Judge the Matcha Before It Becomes Powder
If you want to understand a supplier’s matcha quality, ask about the Tencha first: where it came from, how it was shaded, how it was sorted, and what happened before grinding.
For cafés, beverage brands, distributors, and private-label buyers, those questions reveal more about the raw material than a grade name alone.
