How much caffeine does the tea contain? The fact is not so scary.


Caffeine is contained in tea or coffee, and its content varies greatly depending on the place of origin, variety and production method.
Generally speaking, tea contains 3.5% caffeine, while coffee beans contain 1.1% to 2.2% caffeine. In this way, it seems that tea contains more caffeine. However, the process of making coffee uses hotter water, which will extract more caffeine from coffee beans. Moreover, people drink more coffee beans than tea. Therefore, a cup of brewed espresso usually contains more caffeine than a cup of tea.
