As noted, matcha is remarkably potent, and every person's unique biochemistry will respond to it differently. In Japan, the average rate of consumption is 1-2 cups a day. Many prefer to drink a cup in the morning to prepare for the day, and a cup in the afternoon as a pick-me-up. Experts say there's no level at which matcha becomes toxic or dangerous.
==Matcha Grades==

While it is possible for you to make your own matcha tea powder, it could prove to be labor intensive because you would need a considerable amount of hand-picked tea leaves and have to stone-grind them into a fine powder. It's more convenient to purchase the matcha green powder from tea vendors and online retailers. Teavana carries premium, ceremonial grade matcha tea powder, which is traditionally used in Japanese tea ceremonies. Ceremonial grade matcha reportedly has a creamy, sweet taste compared to the food grade matcha, which has a bitter taste. To prepare a cup of matcha, simply combine 2 ounces of matcha green tea powder with 6 ounces of hot water, and stir until dissolved.
