Green tea and black tea come from the same plant, so the ingredients do not differ only once. Only a few substances by fermentation in black tea can be changed, which will remain in the green tea in their original form.



Related to the caffeine content which primarily means that there is no fundamental difference between green tea and black tea are. Determine how much caffeine contains the tea is only once the origin and tea. Other conditions are the light conditions during growth and the brew time the tea.
