In Tang Dynasty China (618–907), tea leaves were steamed and formed into tea bricks for storage and trade. The tea was prepared by roasting and pulverizing the tea, and decocting the resulting tea powder in hot water, adding salt. In the Song Dynasty (960–1279), the method of making powdered tea from steam-prepared dried tea leaves, and preparing the beverage by whipping the tea powder and hot water together in a bowl became popular. Reparation and consumption of powdered tea was formed into a ritual by Zen (Chan) Buddhists. The earliest extant Chan monastic code, entitled Chanyuan Qinggui (Rules of Purity for the Chan Monastery, 1103), describes in detail the etiquette for tea ceremonies.

Zen Buddhism and the Chinese methods of preparing powdered tea were brought to Japan in 1191 by the monk Eisai. Although powdered tea has not been popular in China for some time, there is now a global resurgence in Matcha tea including in China. In Japan it continued to be an important item at Zen monasteries, and became highly appreciated by others in the upper echelons of society during the 14th through 16th centuries.
