How Much Caffeine Is in Matcha?

A standard serving of ceremonial matcha contains approximately 25-70mg of caffeine, depending on serving size and grade. This is less than a cup of brewed coffee (80-120mg) but more than green tea (25-40mg). The key difference is L-theanine — matcha contains 5x more L-theanine than green tea, which modulates caffeine's stimulant effect to create calmer, more focused alertness without the jitter or crash typical of coffee.
