Matcha and Caffeine: How Much Is in a Cup and How It Compares

Matcha contains caffeine. The amount in a single serving is often stated with a certainty that the reality does not support, because the actual caffeine content varies significantly depending on the grade of the matcha, the amount used, and how it is prepared. What follows is as accurate a picture as the available evidence supports.

The Range

A standard serving of ceremonial grade matcha, prepared as usucha with 1.5 to 2 grams of matcha powder, typically contains between 35 and 70mg of caffeine. The wide range reflects real variation: higher-grade, shade-grown, first-harvest matcha tends to have higher caffeine content than culinary grade, because shading increases caffeine concentration alongside L-theanine and chlorophyll.

By comparison, a standard cup of filter coffee contains approximately 80 to 120mg of caffeine, an espresso 60 to 80mg, and a cup of black tea 30 to 60mg.

Why the Experience Feels Different from Coffee

Caffeine content alone does not determine how alertness feels. Matcha also contains significant L-theanine, which modifies the way caffeine affects the nervous system. The result is a state that most people describe as calm, focused alertness rather than the sharper, more volatile alertness that coffee tends to produce.

This is not a marketing claim. It reflects the known pharmacology of the two compounds and is consistent with what research on the combination suggests. For a more detailed explanation, our article on L-theanine and matcha covers the mechanism.

Hojicha: The Low-Caffeine Option

For those who want a Japanese tea experience without significant caffeine, our Organic Hojicha from Shizuoka contains less than 10mg of caffeine per serving, making it suitable for evenings and for people who are caffeine-sensitive. The roasting process that gives hojicha its warm, toasty character is also what reduces its caffeine content.
