Around 1735, Baisao began selling tea in the various scenic locations in Kyoto. At this time, he had not yet formally given up his priesthood. Baisao never sold his tea for a fixed price. Instead, he carried a
bamboo tube with which he collected donations. He lived an ascetic life, despite his lasting friendships with illustrious individuals, and used the meagre donations from his tea peddling to keep himself nourished. As for his tea equipment, he carried it all in a woven bamboo basket he called Senka ("den of the sages") that he lugged around on a stick over his shoulder. Baisao's method of preparing tea was referred to as
sencha, or "simmered tea". In this method, whole tea leaves would be tossed into a pot of boiling water and simmered for a short period of time. This style of tea differed from
matcha, the most common tea in Japan at the time, which consists of tea leaves ground into a fine powder. The method of brewing tea by grinding it into a powder and whisking it with hot water was popular in
China in the
Song dynasty, during which
Zen Buddhist monks first brought the practice to Japan. By contrast, the Ōbaku school of Zen specialized in brewing loose leaf green tea, a style that had gradually become popular in China during the
Ming dynasty. Sencha partisans of the time opposed the rigid, elaborate formalism of the traditional
chanoyu tea ceremony, which uses matcha. The comparative simplicity of adding tea leaves to water appealed to many Japanese monks and intellectuals (among them Baisao and much of his social circle) who admired the carefree attitude advocated by the ancient Chinese sages. Baisao himself saw tea as a path to spiritual enlightenment, a point he made repeatedly in his poetry. It is not known where Baisao originally obtained his tea leaves from, but by 1738, the sencha method of brewing tea had become popular enough that one of his acquaintances, a tea grower in
Uji, developed new production methods to create a type of tea named after the brewing method. This
sencha tea was made of whole, young leaves which were
steamed and then dried. This technique differs from the typical Chinese method of producing loose leaf tea, which does not involve steaming. Baisao himself praised the tea highly, and the term
sencha has come to refer primarily to the tea leaves produced by this method, not to the method of brewing them. ==Later life==
