MATSUIt is one of the first questions a customer asks over the bar, and one a buyer asks before putting matcha on a menu: how much caffeine is in it? There is no single figure — caffeine moves with the leaf, the harvest, and above all the dose — but the ranges are stable enough to answer straight and set a dose you can stand behind.
How much caffeine is actually in a cup of matcha?
As a working rule, a standard 2 g dose — one level teaspoon, the usual usucha bowl or single-latte serving — carries roughly 60 to 70 mg of caffeine. Scale it with the dose, because dose is what actually moves the total:
- A light 1 g dose — a thin usucha or a gentle latte — lands nearer 30 to 35 mg.
- A standard 2 g dose sits at roughly 60 to 70 mg.
- A fuller 3 g latte dose — common where the matcha has to punch through a lot of milk — runs nearer 90 to 100 mg.
Why so much from so little powder? Because you drink the whole milled leaf rather than steeping and discarding it. Loose-leaf tea extracts only part of the caffeine before the leaf is thrown away; with matcha the leaf is the drink, so all of it goes into the cup — which is why a couple of grams rivals a small coffee.
How does matcha compare to coffee?
Close, and usually a little under — though it depends on which servings you line up, at typical sizes:
| Drink | Typical serving | Typical caffeine | Notes |
|---|---|---|---|
| Matcha (standard) | 2 g powder | ~60–70 mg | Whole leaf; scales directly with gram dose |
| Matcha (latte dose) | 3 g powder | ~90–100 mg | Higher dose to carry through milk |
| Drip coffee | 240 ml (8 oz) | ~95 mg | Varies with bean and brew strength |
| Espresso | 1 single shot | ~63 mg | A double roughly doubles it |
| Steeped green tea | 1 cup, leaf discarded | ~25–45 mg | Only part of the leaf's caffeine is extracted |
So a normal 2 g matcha sits below a standard drip coffee and about level with a single espresso, while a 3 g latte dose climbs into double-espresso territory. Matcha is a genuine caffeinated drink in the coffee band, not a mild one — but where it lands inside that band is a dose decision you control.
Why does matcha feel calmer than the same caffeine in coffee?
Regular matcha drinkers describe this unprompted: the alertness arrives evenly, without the spike-and-crash of a strong coffee. The reason is a compound matcha is unusually rich in — L-theanine, an amino acid that shade-grown teas carry in quantity. It is commonly described as softening the edge of caffeine, so the lift comes on more gradually and reads steadier. We frame that as a widely reported sensory experience, not a medical claim; MATSU makes no efficacy claims. What a café can rely on is simple: customers consistently describe matcha as a calmer, more even alertness at a comparable caffeine level.
Shade matters beyond flavour, then: the weeks under shade that build colour and umami also build the L-theanine, as the piece on first-harvest, single-origin matcha explains.
Does shade-growing and first harvest change the caffeine?
Yes — both push caffeine up, which helps explain the spread between grades.
- Shading raises it. Covering the plants for the weeks before harvest — the step that makes tencha, the leaf matcha is milled from — leads the leaf to hold more caffeine and L-theanine than an unshaded green tea. It is part of why matcha and gyokuro sit at the higher end of the green-tea range.
- Younger leaf carries more. The tender leaves of the first harvest (ichiban-cha), picked in spring for premium grades, tend to carry more caffeine than the older leaves of later harvests used for everyday grades — so a premium grade tends toward the upper end of the range, an everyday grade toward the lower.
Two cautions keep this honest. These are tendencies across a crop, not fixed numbers — season, weather, and lot all move them, which is why we quote ranges. And the gap between grades stays modest next to dose. Grade and harvest tilt the number; dose sets it.
What changes the caffeine in the cup you actually serve?
Dose and grade we have covered — both move the number, dose by far the most. Two things people assume change caffeine do not:
- Milk, water, and volume — not a lever. More milk dilutes the taste, not the caffeine: you still consume every particle of powder, so a weaker-tasting latte is not a lower-caffeine one unless you used less powder.
- Temperature — not a lever. Hot or iced, whisked or shaken, you drink the whole leaf, so preparation changes texture and flavour, not caffeine. Iced matcha is not “milder”; it is the same dose.
How should a café think about caffeine per serving?
Anchor caffeine to your dose and keep it consistent, and the question answers itself. A cheat sheet to hold in mind:
- 2 g single ≈ a light coffee, ~60–70 mg — a sensible everyday default.
- 3 g latte dose ≈ a strong coffee or double espresso, ~90–100 mg — for drinks that carry through milk.
- Lighter option ≈ a smaller dose in more milk — lower caffeine per drink, no separate product.
Write that fixed dose into the recipe rather than leaving it to each barista, and caffeine stays predictable — and the cup stays consistent too, since dose also drives colour and strength of flavour.
Can you match caffeine to grade before buying wholesale?
You cannot read a grade's real character — caffeine band, colour, how it carries through milk — off a label, and precise per-lot caffeine figures are not something we publish or promise. What you can do is taste the real grades against your own doses and watch how they behave. That is what a tasting kit is for.
Run it the way your bar runs — your water, your milk, your dose — so the cup you judge is the cup you will pour. Because MATSU is producer-direct — grower-level sourcing without the usual chain of trading houses and importers — the lot you taste is the lot you order, season after season, so a fixed dose keeps meaning a fixed drink. A single order runs up to roughly 30 kg. When you are ready, request the professional catalogue for full specs and pricing across all eight grades ($390–$1,050 per kilogram, FOB Japan).
Frequently asked questions
How much caffeine is in a cup of matcha?
As a working rule, a standard 2 g dose — one teaspoon, the usual usucha or single-latte serving — carries roughly 60 to 70 mg of caffeine. Published figures vary widely, so treat any single number as an estimate. A light 1 g dose lands nearer 30 to 35 mg; a fuller 3 g latte dose nearer 90 to 100 mg. Because you drink the whole milled leaf rather than a steeped infusion, matcha carries more caffeine per gram of powder than the same weight of leaf brewed and discarded as loose tea.
Does matcha have more caffeine than coffee?
Usually a little less per serving, though it depends on the doses you compare. A standard 2 g matcha at roughly 60 to 70 mg sits below a typical 240 ml drip coffee at around 95 mg, and close to a single espresso at roughly 63 mg. Both scale with dose: a double espresso or a 3 g matcha latte pushes higher. The more useful difference is not the milligram count but how the caffeine is delivered — matcha carries L-theanine alongside it, which is why an equal dose tends to read steadier.
Why does matcha feel calmer than coffee?
Because matcha is a shade-grown tea, it is unusually rich in L-theanine, an amino acid green tea is known for. L-theanine is commonly described as taking the sharp edge off caffeine, so the lift arrives more gradually and with less of the jittery spike people associate with a strong coffee. This is a widely reported sensory difference, not a medical claim; what a café can rely on is that customers frequently describe matcha as a steadier, more even alertness at a similar caffeine level.
Does shade-growing or first harvest change the caffeine?
Both tend to raise it. Shading the plants for the weeks before harvest pushes the leaf to hold more caffeine and L-theanine, part of why matcha and gyokuro sit higher than ordinary green tea. Younger leaves also carry more caffeine than older ones, so first-harvest (ichiban-cha) leaf used for premium grades tends toward the higher end of the range, while later harvests used for everyday grades tend lower. These are tendencies across a crop, not fixed numbers — season and lot move them.
What changes how much caffeine ends up in the cup?
Dose is the biggest lever by far: double the powder and you roughly double the caffeine, which is why a 3 g latte carries more than a 2 g bowl. Grade and harvest shift it more modestly — a first-harvest premium grade tends higher than an everyday later-harvest one at the same weight. Milk, water volume, and temperature do not change the caffeine, since you consume the whole powder regardless; they change flavour and strength of taste, not the milligrams. To control caffeine per drink, standardise the gram dose.
How should a café think about caffeine per serving?
Anchor it to your gram dose and keep that dose consistent. A 2 g single is roughly a light-coffee equivalent at 60 to 70 mg; a 3 g latte dose runs nearer 90 to 100 mg, in double-espresso territory. Weigh or scoop to a fixed dose so every drink lands in the same band, and you can answer a customer honestly without guessing. If your menu wants a lighter option, a smaller dose in more milk gives it without a different product.
Is decaf or low-caffeine matcha a thing?
True decaffeinated matcha is rare and generally not what a specialty café wants, because the processing that strips caffeine tends to dull the colour and flavour the grade was grown for. The practical way to serve a lighter cup is a smaller gram dose in more milk, which lowers the caffeine per drink while keeping a real, vivid matcha. If a customer needs to avoid caffeine entirely, matcha is not the drink to reach for — but for merely lighter, dose is the honest lever.
