Pick up any tin of matcha and most of what is printed on it is decoration. "Ceremonial grade", "Premium", "Authentic Japanese", or "Superior quality." None of those are defined by anyone. There is no certifying body, no standard, no regulations.
A few things on the label do carry information. Here is what to look at, roughly in order of how much it tells you.
1. A named region, not a country
"Product of Japan" is the weakest origin claim that is still technically true. It covers every prefecture and every quality tier.
What you want is a place: Uji, Nishio, Yame, Kagoshima. Better still, a named town or garden. A brand that knows exactly where its tea grew will say so, because it took effort to arrange and it is the most valuable thing they can tell you.
Vagueness here usually means the tea was bought through intermediaries who did not know the origin either. It has always been a soft signal. In a shortage it is a loud one.
Watch also for the difference between where tea was grown and where it was packed. "Packed in Japan" and "blended in Japan" are not origin statements.
2. A harvest year
Matcha is perishable. It loses colour and flavour steadily from the moment it is milled, and faster once the tin is opened.
A harvest year, or better, a milling date, tells you what you are actually buying. Its absence tells you something too. During a shortage, older stock moves, and the tins that do not print dates are the ones you should assume are carrying it.
3. Which picking
First harvest, ichibancha, first flush. All the same thing: leaves picked in spring, the plant's best material. Later pickings are coarser and more bitter.
If a tin claims first harvest but skips the year and the region, treat the claim as marketing rather than fact. The three go together on honest packaging.
4. A cultivar name, if you are lucky
Names like Samidori, Okumidori, Asahi, Gokou. These are tea plant varieties, and each has a recognisable character. Very few brands print them, because very few brands know.
You do not need this to buy well. But a cultivar on the label is a strong signal that whoever packed the tin is close to the source.
5. The ingredient list
It should say one thing: green tea. That is it.
If you see sugar, milk powder, maltodextrin, rice starch, or "natural flavour," you are holding a drink mix. That is a legitimate product, but it is not matcha and it should not be priced or brewed like it.
Colour additives are a rarer problem, but a powder that looks radioactive green next to everything else on the shelf is worth a second look. Real matcha is a deep, slightly muted green. Some non-Japanese powders come out brighter than the genuine article.
6. The price, read backwards
First-harvest tencha has cleared at record prices at Japanese auctions for two years running. There is no route by which genuine first-harvest Uji matcha reaches a shelf cheaply in 2026.
A cheap tin labelled "ceremonial" is lying about the ceremony, not the price.
The reverse is not true, unfortunately. A high price proves nothing on its own. It only becomes meaningful when the region, the year, and the picking are all on the tin as well.
