Matcha and Caffeine: How much caffeine is in matcha?

Matcha contains caffeine, yes. But not the same caffeine as your morning espresso. Or rather, the same molecule, but in a biochemical context that changes everything.

This guide answers the most frequent question about matcha: how much caffeine per cup, how it compares to coffee and green tea, and why matcha provides energy without jitters.

How many mg of caffeine per cup

One gram of matcha contains approximately 30 to 35 mg of caffeine. Since the standard dose per cup is 1.5 to 2 g of powder, a cup of matcha provides between 45 and 70 mg of caffeine.

This figure varies depending on three factors.

1 - The grade. Ceremonial grade matcha, made from shaded first flush leaves, contains slightly more caffeine than culinary matcha from a later harvest. Prolonged shading stimulates caffeine production in the leaves.

2 - The dosage. 1.5 g will yield about 50 mg of caffeine. 2 g will yield about 65 mg. 3 g (for a stronger matcha or koicha) will yield nearly 100 mg. Dosage is the most direct way to control your caffeine intake.

3 - Water temperature. Hotter water extracts more caffeine. At 70 °C (recommended temperature), extraction is optimal without excess. At 90 °C or higher, the extracted caffeine increases, as does bitterness.

Matcha vs. Coffee vs. Green Tea

Matcha falls between green tea and coffee in terms of raw caffeine. But the comparison ends there, because the type of energy is radically different. Matcha and coffee do not produce the same effect on the body and mind, despite having the same caffeine molecule.

Why matcha doesn't cause jitters

If matcha contains almost as much caffeine as coffee, why doesn't it cause the same jitters? The answer lies in one word: L-theanine.

L-theanine is an amino acid naturally present in tea plants, and matcha contains 3 to 5 times more of it than brewed green tea. This high concentration is due to the shading of the tea plants before harvest, which forces the plant to produce more L-theanine to compensate for the lack of light.

L-theanine crosses the blood-brain barrier and stimulates the production of alpha waves in the brain. These waves are associated with a state of relaxed alertness: the mind is calm yet alert, relaxed yet focused. This is the state meditators seek and that Zen monks cultivated with matcha since the 12th century.

When caffeine and L-theanine work together, they produce a synergistic effect documented by several studies. Caffeine provides energy and alertness. L-theanine smooths the caffeine peak and prevents the crash. The result is sustained concentration for 4 to 6 hours, without agitation, palpitations, or the sudden fatigue that follows an espresso.

This is also why many former coffee drinkers switch to matcha: the same energy, but more stable and pleasant. No shaky hands, no racing heart, no 2 PM crash.

Can you drink matcha in the evening?

The answer depends on your individual sensitivity to caffeine.

The half-life of caffeine in an average adult is 4 to 6 hours. This means that half of the caffeine from matcha drunk at 5 PM will still be active in your system between 9 PM and 11 PM. For most people, this is enough to disrupt falling asleep.

Practical rule: If you are sensitive to caffeine, stop drinking matcha before 2-3 PM. If you tolerate caffeine well (you can drink coffee after dinner without problems), matcha in the late afternoon will probably not be an issue.

Evening alternative: A matcha latte with hot milk and a reduced dosage (1 g instead of 2 g) can work for people who metabolize caffeine well. L-theanine provides a relaxing effect that promotes relaxation, but caffeine is still present. When in doubt, hojicha (roasted Japanese tea, almost caffeine-free) is a better option for the evening.

FAQ: matcha and caffeine

Does decaffeinated matcha exist?

Technically yes, but it is very rare and the decaffeination process alters the aromas and destroys some of the catechins. Decaffeinated matcha loses much of what makes matcha interesting. If you are looking for a caffeine-free drink with antioxidants, rooibos or herbal teas are better options.

Does matcha in a latte contain the same caffeine as pure matcha?

Yes. Milk does not change the caffeine content. Whether you prepare your matcha with water or as a latte, the amount of caffeine depends solely on the quantity of powder used (1.5 to 2 g = 50 to 70 mg of caffeine).

How many cups of matcha equal one coffee?

In pure caffeine, it takes about 1.5 to 2 cups of matcha to equal one espresso. But the felt effect is different: coffee gives a quick, short boost, while matcha gives a gentler, longer energy. Comparing the two solely on mg of caffeine misses the point.

Does culinary matcha have less caffeine?

Slightly. Culinary matcha often comes from later harvests with shorter shading, which slightly reduces the caffeine (and L-theanine) content. But the difference is small: about 25 to 30 mg per gram instead of 30 to 35 mg. In practice, the grade is not a significant lever for reducing your caffeine intake. Dosage (less powder per cup) is much more effective.

Is caffeine in matcha addictive?

Caffeine, regardless of its source, can create a slight physical dependence with withdrawal symptoms (headaches, fatigue) if you suddenly stop it after regular consumption. This is identical for coffee, tea, and matcha. Gradually reducing rather than stopping abruptly avoids these inconveniences.

Is matcha better than coffee for anxious people?

For many people prone to anxiety, yes. L-theanine attenuates the anxiogenic effect of caffeine and promotes a calm state. But the response varies among individuals. If coffee makes you anxious, matcha is an alternative worth trying, starting with a light dosage (1 g). The overall benefits of matcha include this unique soothing effect among caffeinated beverages.

Want stable energy without the crash? Our ceremonial grade matchas are rich in L-theanine thanks to prolonged shading, for the best caffeine-serenity balance.
