Matcha is a finely ground and powdered high quality Japanese green tea. In Japan it is a very important part of the tea ceremony, or it also can be added to certain foods and beverages to provide its natual color and flavor. This tea is made with very specific tea leaves that have been covered a few weeks prior to harvesting, to slow growth and thus produce a greater amount of amino acids (L-Theanine) which gives the leaves natual sweetness. The leaves are then laid out flat on the ground to dry. Once dried, they are called Tencha. Tencha can then be made into the stone-ground Matcha. There are different grades of Matcha. The highest grades are very expensive and they are very sweet, intensely flavored and has bright green color. This is due to the significant amounts of amino acids in the tea. Less expensive versions are somewhat less intense flavor, some bitter and some yellowish green. These versions are suitable for cooking purpose. Matcha is considered as the healthiest drink on earth because it contains a greater concentration of antioxidants than any other fruit or vegetable on the planet.
