Green tea comes in many varieties, including matcha, sencha, and gyokuro. The precise amount of caffeine in green tea will depend on the type of tea and how it’s brewed.
The most common type of green tea (sencha) has a moderate amount of caffeine.
Green tea caffeine levels
Many recent studies have focused on caffeine from 8-ounce (237 ml.) cups of green tea and coffee.
The amount of caffeine in coffee varies depends on the type of beans, how they are roasted, and the method of brewing.
An 8-ounce cup of brewed loose-leaf green tea contains between 25 and 40 mg of caffeine.
An eight-ounce cup of coffee has considerably more- somewhere between 70 and 140 mg of caffeine depending on potency. Espresso coffee is more potent and contains more.
Matcha contains more caffeine than brewed green tea
When you drink matcha you consume the leaves. Matcha is also more concentrated, so it contains more caffeine (by volume) than other green teas.
The servings are usually smaller, though. A bowl of Ceremonial-grade matcha is prepared with about 4-6 ounces of water and it contains more caffeine than a cup of brewed tea.
How much more? A bowl of matcha contains about 60-80 mg. of caffeine. Like coffee, the precise amount depends on potency.
