Caffeine in matcha is different than caffeine in a cup of coffee and the quick answer is yes matcha has less caffeine than coffee does, about a quarter as much (per cup). You can say roughly 25mg of caffeine for matcha and roughly 100mg or more for coffee, other factors such as quality of the matcha and different beans for coffee can attribute to some variance. So you can now rest assured it’s about a fourth the caffeine as brewed coffee.
