| A cup of coffee has way more caffeine than tea. Coffee has 163mg per cup, black tea 42mg and green tea 25mg.[0][1][2] 1kg of dry tea does have more caffeine than 1kg of coffee beans, according to Wikipedia[3] > Tea contains more caffeine than coffee by dry weight. A typical serving, however, contains much less, since less of the product is used as compared to an equivalent serving of coffee. Also contributing to caffeine content are growing conditions, processing techniques, and other variables. Thus, teas contain varying amounts of caffeine Also kinda interesting: I've often seen people opt for an espresso instead op a cup of coffee, because they say they need the caffeine. But an espresso has only 77mg of caffeine, way less caffeine than a cup of coffee. [4] (Unless you fill a coffee cup with espresso shots, but who does that?)
