Coffee is made from a coffee bean (actually a seed) that is dried, roasted and ground. One cup (or 8 oz.) of brewed coffee contains about 95 mg of caffeine. It contains antioxidants and other nutrients. Matcha is made from a plant grown in the shade. The leaves are stripped of their stems and veins and then ground into a powder. One cup (or 8 oz.) of matcha prepared in water contains about 20-44 mg of caffeine. Matcha is high in antioxidants and a compound called L-theanine. This compound helps stabilize the energy boost you get from matcha's caffeine so you don't get the same energy crash you can from coffee.
