A typical cup of green tea falls in the range of 25-45 mg of caffeine per 8oz. cup. That’s less than black tea, which is usually 45-75 mg per 8oz. cup. And far less caffeine than coffee, which has between 80-110 mg per 8oz. cup. But don’t generalize too quickly, matcha green tea has 60-70 mg of caffeine per 8oz. cup!
Green tea naturally contains caffeine, but there is a surprising amount of nuance between different types. How the tea is grown, processed, and steeped affects the caffeine content. Just by learning how the tea is made, you’ll know which teas have higher amounts of caffeine. And different methods of brewing your tea will give you control over the caffeine content in your cup.
