So what is matcha? Zen Green Tea’s matcha starts from our green tea plants grown on the slopes of Kyoto, Japan. Its incredible health benefits come from the unique process in which the tea leaves are shaded, hand picked, strictly graded and then stone ground into a fine, vibrant green tea powder. The result is a premium green tea with 137x the antioxidants of standard green tea. What’s more, each cup delivers the same energy as a cup of coffee but smoothly, over 4-6 hours – no spikes and slumps – with only 1/10 of the caffeine.
