The same kind of tea tree as gyokuro is used. The process of Matcha tealeaf's growing and the methods of blocking the sunrays are the same as gyokuro tea leaves. One difference is that Matcha tealeaves are first steamed and are not rolled. But each leaf is spread and dried in the sun. They grind tealeaves into powder with a fine grade stone mill. The stems and stalks are removed and only tealeaf blades are used. The powdered tea can become bad easily. When you buy it at the shop, you should not buy much at one time. You are recommended to buy it a little at a time at the shop where it is ground into powder. The difference between thick and thin tea depends on the place and the process of the cultivation, which causes a different taste of each tea.
