- Determining the levels of caffeine in a tea can be very difficult because there are so many variables that need to be considered. Such variables include, soil, vegetation, water temperature, steeping time etc.
- The steeping time can change the amount of caffeine that is released into your cup of tea. A black tea doesn’t necessarily have more caffeine than a green tea, but it tends to have that stereotype because you generally steep it longer than a green or white tea.
- Adding herbs and spices changes the level of caffeine because there is less of the actual Camillia Sinensis plant in the brew.
- Studies of caffeine levels in tea are all different; the scientific conditions in which the study takes places are also different then how each and every one of us brews tea at home.
- The caffeine in coffee is not the same in tea, it enters your blood system a lot slower and gives you a nice gradual increase of energy rather than that jolt you get from coffee.
