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.
Many people use boiling water to brew green tea, or brew green tea for more than three to four minutes. This increases the level of caffeine in your cup. Instead, use simmering water and brew for 30 seconds to four minutes, with an optimal brew time of one-and-a-half minutes to three minutes for many green teas. Drink whole-leaf green tea instead of green teabags. Teabags have more caffeine than loose-leaf tea (usually).
