Caffeine

A cup of Taiwan Aged Dark Tea carries a typical estimate of 35 mg of caffeine, within a range of 20 to 45 mg depending on leaf amount, water temperature and steeping time. Figures are estimates for a 240 ml cup. Better earlier in the day if you are sensitive to caffeine. The caffeine planner turns this into a daily total.
