2010 Spring 1000 Mesh Organic Matcha Powder
Matcha, the most famous, and commonly-drank tea in Japan, is a finely-powdered green tea. Matcha originates from China Tang Dynasty(618-907), and were the only tribute way of drinking tea in Tang & Song Dynasties(960-1279) in China. At that period, the preparation of Matcha is more complicated, and has more steps than the current Japanese Matcha ceremony.
Then in Ming Dynasty(1368-1644), the Emperor, Zhu Yuanzhang banned the production of cake teas, and encourage the loose leaves tea for his personal reason.(this mostly connected to his humble origin). Hence, from then on, loose leaves tea has been popular in China till now.
