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.
Although there is caffeine in green tea, it contains less caffeine than black tea, and in turn black tea has a lot less caffeine than coffee. So if youâre looking to reduce your caffeine intake (but not eliminate it completely) green tea is a good choice.
