Green tea contains less caffeine than coffee, but the exact amount can vary depending on factors like the type of green tea, brewing time, and serving size. On average, an 8-ounce cup of green tea contains about 28-38 mg of caffeine, while a cup of coffee typically has around 95 mg. However, matcha green tea powder is an exception, containing about 70 mg of caffeine per serving due to its concentrated form.
