Estimates based on an average of 33 mg caffeine and 18 mg L-theanine per gram of matcha. Real values vary by harvest, brand, and cultivar.
How to use the result
- Under 100 mg — light, sustained focus. Most usucha bowls and lattes land here. Good morning or early-afternoon dose.
- 100–150 mg — solid working dose. A strong latte or thicker bowl. Equivalent to a single coffee but with steadier feel.
- 150 mg+ — koicha territory. Treat it like a strong coffee and watch your total daily intake (most adults stay under 400 mg/day).
