Do all teas have the same caffeine content?
Since all teas are produced from Camellia sinensis, they naturally contain caffeine. Processing other than decaffeination does not change the caffeine content. All teas have approximately the same amount of caffeine, falling within a range of 25 to 60 mg of caffeine in a 6-oz. cup. For comparison, coffee has about 120 mg per 6 ounces.
