Matcha contains a variable amount of caffeine depending on the quality, amount of powder used, and preparation method. Generally:
- Matcha has about 20–45 mg of caffeine per gram of powder
- A typical serving size is 2–4 grams (about 1/2 to 1 teaspoon), which means a cup of matcha can contain roughly 38–176 mg of caffeine
- Common estimates place an 8 oz cup of matcha at around 60–70 mg of caffeine
- Some sources specify about 64–72 mg of caffeine per 2 grams of matcha powder
- For comparison, a typical cup of brewed coffee contains about 80–140 mg of caffeine, so matcha's caffeine content is somewhat comparable but usually slightly less or similar depending on serving size
The caffeine in matcha is released more gradually due to other compounds like L-theanine, providing a more sustained and less jittery energy boost compared to coffee
. In summary, expect about 60–70 mg of caffeine per standard cup of matcha made with 2 grams of powder, with a range from roughly 38 to 176 mg depending on how concentrated the matcha is. This is generally less or similar to a cup of coffee but more than regular green tea
