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.
At a given weight, tea contains more caffeine than coffee, but this doesnât mean that a usual portion of tea contains more caffeine than coffee because tea is usually brewed in a weak way. Some kinds of tea, such as oolong and black tea, contain higher level of caffeine than most other teas. Among six basic teas (green, black, yellow, white, oolong, dark), green tea contains less caffeine than black tea and white tea contains less than green tea. But many studies found that the caffeine content varies more among individual teas than it does among broad categories.
