100% Japanese green tea powder, full of antioxidants and flavor. This is ceremonial grade, so it is high quality and pure, used in the Japanese tea ceremony. It comes in this 1 oz. air tight canister to keep your green tea powder fresh. Though this is only 1 ounce of tea, it goes a long way. Up to 1/4 teaspoon can make up to 6 ounces of Matcha, depending on how strong you like it. We recommend using a Japanese bamboo whisk to properly prepare it.
