“Ceremonial grade”, “premium grade”, “café grade”, “culinary grade”: these words appear on almost every matcha price list, and they are useful shorthand. But there is no official grading standard for matcha in Japan or elsewhere that defines them. Each supplier decides what its own grade names mean, and two suppliers’ “ceremonial” products can differ in harvest, region, cultivar, milling and price.
That is not a scandal. It simply means grade names are a starting point for a conversation, not a specification.
01 · What grades mean
What the names usually signal
In practice, grade names loosely encode a few underlying variables:
- Harvest: first harvest for higher grades, later harvests for lower ones
- Leaf position and age: younger leaves higher, older leaves lower
- Color and taste: vivid green and sweet, umami-rich taste at the top; duller color and more astringency lower down
- Milling: finer stone milling higher, coarser or faster milling lower
- Origin: well-known regions and specific fields at the top, blends lower
Because each supplier weights these differently, “ceremonial” from one company can sit below “premium culinary” from another. Buyers who compare grade names across suppliers are comparing labels, not products.
02 · The problem
Why it matters commercially
- You may pay a premium for a name rather than for characteristics your product needs.
- Your own product claims (“ceremonial grade”) rest on a supplier’s private definition.
- When you switch suppliers or the supplier changes its range, the label may not travel with the product.
03 · Specify
What to specify instead
Replace the grade name with points a supplier can confirm and a lab or panel can check.
| Attribute | How to specify it |
|---|---|
| Harvest | First harvest of the current year, or as agreed |
| Origin | Region(s), and whether blending is permitted |
| Cultivar | Named cultivar(s) or “supplier’s blend” |
| Color | Reference sample and, if available, colorimeter values; see how to specify matcha color |
| Particle size | Median particle size or sieve, and milling method; see particle size and milling |
| Taste profile | Described in the intended use, with a retained reference sample |
| Testing | Panel of tests provided per lot |
| Shelf life and packaging | Months from milling, packaging type |
04 · Use first
Start from the use, then find the grade
The most useful question is not “which grade?” but “what does the matcha need to do?” A latte needs color that survives milk and low astringency; a retail tin for whisking needs sweetness, aroma and fine texture; an ice cream needs color retention in cold fat. Our note on matcha for lattes versus retail tins shows how the same buyer ends up with two different briefs.
Send the specification and ask which of their products meets it. You will get useful, comparable answers, and often a product you would not have picked from the price list.
05 · Claims
Using grade words on your own packaging
If you print “ceremonial grade” on your product, you are making a claim you define. Keep an internal definition tied to your specification and supplier, so the claim stays true when lots or suppliers change. Where a market regulates descriptive claims, check locally.

07 · FAQ
Frequently asked questions
Is there any official matcha grading standard?
No. There is no government or industry-wide grading standard that defines ceremonial, premium or culinary matcha. Suppliers define their own grade names, which is why specifications rather than names should drive comparisons.
Can I still use “ceremonial grade” on my packaging?
You can, provided the claim is not misleading in your market and you can substantiate what you mean by it. Keep an internal definition tied to your specification and supplier so the claim stays true when lots change.
What should I ask for instead of a grade?
Harvest and year, origin and blending policy, cultivar or blend, color reference, particle size and milling method, a taste description with a retained sample, the test panel per lot, and packaging and shelf life.
