Matcha has a reputation for a steadier lift than coffee. But how much caffeine does it actually hold, and how does a cup compare with the coffee you’d normally order? The short answer: less than coffee in most cups, though the figure depends on how much powder goes in.
How much caffeine is in matcha
Matcha is finely ground green tea leaves, so you drink the whole leaf rather than an infusion. A teaspoon of powder, roughly 2 grams, typically contains around 60 to 70 milligrams of caffeine. The exact number varies with the brand and grade, so treat it as a ballpark.
How it compares
- A matcha latte made with one teaspoon: around 60 to 70 mg. Milk adds no caffeine.
- A standard 8 oz cup of brewed coffee: commonly around 95 mg, though it varies widely.
- A single espresso shot: roughly 60 to 65 mg.
- A large café iced coffee: often well above 100 mg.
Add a shot of espresso to your matcha and you get a dirty matcha, which stacks the two caffeine sources together.
Why matcha feels gentler
Matcha also contains L-theanine, an amino acid. Many people describe matcha as alert without the jolt, and researchers have studied theanine’s role in calm focus. The evidence is still developing, so treat that as a common experience rather than a guarantee.
Adjusting your dose
- Use half a teaspoon for a lighter cup.
- Add an espresso shot for a stronger, dirty matcha.
- Check the label, since grades differ in both colour and caffeine.
