Matcha is a ground-up version of green tea leaves that’s a caffeinated alternative to coffee. It has 70 milligrams of caffeine per 8-ounce cup. Coffee has 96 milligrams for the same portion, but matcha drinkers say that their energy is more consistent, with less of a dive after the caffeine effect wears off. By consuming the leaves directly (instead of steeping them in water as you would green tea), you get more nutrients and antioxidants in one punch. At about 10 calories per teaspoon, matcha is a calorie-friendly way to get green tea flavor, and it dissolves easily in milk or water. Instead of trying to find a specialty shop that blends matcha up for you, you can now purchase the green stuff in bottled form at your local grocery store.
