Yes, matcha does contain caffeine. On average, matcha contains about 19 to 44 milligrams of caffeine per gram of matcha powder. A typical serving, which uses around 2 grams of matcha powder, would contain approximately 38 to 88 milligrams of caffeine. This caffeine content is higher than most other green teas but generally lower than the caffeine content in coffee. Matcha also contains L-theanine, which slows caffeine absorption and provides a calm, sustained energy boost without the jitters often associated with coffee caffeine. The exact caffeine amount can vary based on leaf quality, powder amount, and preparation method.
