Four costs, and they compound
SHADING. Covering a field for two to four weeks before harvest cuts the yield of that harvest substantially and costs labour and materials every year. Everything called matcha is made from shaded leaf; how long and how well it was shaded is the first fork in the price. THE HARVEST. First-flush leaf from the spring picking is softer, sweeter and much more expensive than later harvests. A single field yields first flush once. Later pickings from the same bushes go into cheaper grades, and the difference in the cup is not subtle. DE-STEMMING. Tencha is the leaf blade with the stem and vein taken out. Removing them discards material that has already been grown, shaded, picked and steamed, and stem left in shows immediately as a duller colour and a coarser texture. MILLING. A granite mill produces on the order of thirty to forty grams an hour and cannot be pushed faster without heating the powder, which costs colour and aroma. That is a hard physical ceiling on a machine, and it is why milling is a real fraction of the price of a good matcha and a negligible one for a cheap matcha ground fast in metal.
What the price bands actually contain
There is no regulated grading system, so nothing below is a standard — it is a description of what tends to sit where. At the bottom of the range, in bulk catering and supermarket tins, expect later-harvest leaf, stem included, fast metal milling, and frequently blends that are not Japanese at all. The colour tends to olive or yellow-green rather than jade, the texture is gritty between the fingers, and the taste is dominated by bitterness with little sweetness behind it. It works in a cake, where sugar and fat cover it, and it is unpleasant whisked in water. In the middle, expect Japanese single-region leaf, later-flush or a blend of flushes, stone-milled, sold as a named blend by a producer. This is the band most people drinking matcha daily are actually in, and a good one at this level beats a badly kept expensive one comfortably. At the top, expect first-flush leaf from a named district, often Uji, Nishio or a specific Kagoshima grower, stone-milled, sold in small tins with a mill date. Koicha grades — thick matcha — sit here, because thick preparation uses several times the powder and exposes any bitterness ruthlessly.
Why prices moved sharply, and what that did to the shelf
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Demand outside Japan grew far faster than tencha production could, and the constraints are physical: bushes take years to come into full bearing, shading structures take capital, and the mills have a fixed rate. Through the mid-2020s major Japanese producers introduced purchase limits and allocations and prices rose. The consequence for a buyer is not mainly the price. It is that a supply squeeze on the top grades pushes demand down the ladder and pulls new supply in from outside Japan, so the middle of the market has become harder to read: more blending, more unstated origin, and more product sold on packaging rather than on a producer's name.
The three things worth paying for, in order
FRESHNESS FIRST. Matcha is the most perishable thing in a tea cupboard — it is a powder with enormous surface area, and it loses colour and aroma to air, light and warmth in weeks once opened. A cheap fresh tin beats an expensive stale one every time, so a mill or packing date on the tin is worth more than most of the words on it. ORIGIN SECOND. A named district, and better a named producer, tells you far more than any grade word. Which brings us to the third point. GRADE WORDS LAST, AND MOSTLY NOT AT ALL. "Ceremonial" and "culinary" have no legal or industry definition and no certifying body behind them. They are useful as a rough signal of what the seller intends the product for, and they are not evidence of anything about the leaf.
