What is the caffeine content in tea vs. coffee?
[Back To Top] The caffeine content for an average cup of green tea is usually stated at around 15 – 20 mg. per 8 oz. cup. Coffee, by comparison, can range from 100 – 140 mg per 8 oz. cup, depending on the method of brewing used. Caffeine content in highly oxidized teas, like very dark oolongs and black tea, can range up to 50 mg of caffeine per 8 oz. cup, almost half that of coffee. In our experience, the greener and fresher the tea, the lower the caffeine content.
