How much caffeine is in matcha
Yes, matcha contains caffeine: roughly 19 to 44 mg per half-teaspoon (about 1 gram) of powder. A typical drink made with one to two grams has about 38 to 88 mg, compared with about 95 mg in a cup of brewed coffee and about 30 mg in a cup of steeped green tea.
How much caffeine is in a serving of matcha
Because you consume the whole ground leaf rather than an infusion, matcha delivers more caffeine per gram than steeped tea. Published figures cluster around 19 to 44 mg of caffeine per gram of powder, and a standard bowl or latte uses one to two grams.
| Drink | Serving | Caffeine |
|---|---|---|
| Matcha (usucha) | 2 g powder | About 38 to 88 mg |
| Matcha latte (cafe) | 2 to 4 g powder | About 40 to 130 mg |
| Brewed coffee | 240 ml cup | About 95 mg |
| Espresso | Single shot | About 63 mg |
| Steeped green tea | 240 ml cup | About 30 mg |
| Black tea | 240 ml cup | About 47 mg |
Why does matcha caffeine vary so much
Three things move the number: the leaf, the grade and the scoop. Shaded first-harvest leaves (ceremonial grade) are naturally higher in caffeine than later harvests, so premium matcha is usually at the top of the range. And because cafes often use two heaped teaspoons in a large latte, a cafe matcha can match or exceed a coffee, while a light home-whisked bowl may be half that.
Does matcha feel different from coffee
Many people find matcha gives a steadier, less jittery alertness than coffee. The usual explanation is L-theanine, an amino acid concentrated by shading, which research suggests can smooth the stimulant edge of caffeine and promote calm alertness when the two are taken together. The effect varies between people, and matcha is still a caffeinated drink, so it can absolutely keep you awake if you have it late in the day.
How much matcha is safe in a day
The European Food Safety Authority considers up to about 400 mg of caffeine a day safe for most healthy adults, with about 200 mg a day the commonly cited guideline during pregnancy. On the figures above, that puts a sensible ceiling around four to eight typical matcha servings a day for most adults, and fewer if you also drink coffee, tea or energy drinks. If you are pregnant, sensitive to caffeine or have a heart condition, it is worth counting your total from all sources and talking to a health professional.
Common questions
- Does matcha have more caffeine than coffee?
- Usually a little less per serving. A typical matcha made with two grams of powder has about 38 to 88 mg of caffeine versus about 95 mg in a brewed cup of coffee, but a strong cafe matcha latte can reach coffee levels.
- Does matcha have more caffeine than green tea?
- Yes. Because you drink the whole powdered leaf, a matcha serving typically carries two to three times the caffeine of a cup of steeped green tea.
- Is matcha caffeine released more slowly?
- The caffeine itself is the same molecule, but matcha also contains L-theanine, which research suggests can take the jittery edge off caffeine and support calmer alertness. Many people report a smoother effect than coffee, though individual responses vary.
- Can I drink matcha while pregnant?
- Commonly cited guidance is to keep total caffeine under about 200 mg a day during pregnancy, which one or two modest matcha servings would usually fit within. Check your total from all sources and ask your midwife or doctor.
