Pick a tea family, how you brew, and how many cups you drink. The estimate uses mid-range published values scaled by volume and method — useful for comparing days, not for medical dosing.
Estimate
60 mg
About 30 mg per cup × 2 cups. Typical published ranges for green tea: 20–45 mg / cup. Not medical advice — leaf amount, brand, and steep time all move the number.
Notes
- Matcha uses a 2 g whisked serving baseline; leaf teas use a typical cup mid-point.
- Gongfu slightly raises the factor (more leaf, many short steeps). Cold brew usually pulls less.
- Deeper reading: Caffeine by tea type.
- Not medical advice. Sensitive groups should follow a clinician’s caffeine guidance.
