The amount of caffeine in an 8 ounce cup of regular brewed coffee is between 80 and 120 milligrams. How much caffeine is in a cup of tea?There are between 40 and 50 milligrams of caffeine in a typical eight ounce cup of brewed black tea or green tea steeped for three to five minutes. An eight ounce cup of similarly brewed decaffeinated tea contains approximately 4 milligrams of caffeine (99.6% caffeine free). The amount of caffeine in a typical cup of regular brewed coffee is between 80 and 120 milligrams.
