A Department of Nutritional Services report provides the following ranges of caffeine content for a cup of tea made with loose leaves: 1  Black Tea: 23 - 110 mg. 2  Oolong Tea: 12 - 55 mg.  Green Tea: 8 - 36 mg.
It found that the average caffeine level in the cups of tea (black English style teas) was 40mg vs 105mg in the average cup of drip coffee. The amount of caffeine in coffee or tea depends on a number of factors, including the method and length of brewing or steeping. With tea, studies also show that leaf location on the tea plant affects content of caffeine in that tea.
