The Song Dynasty marked the undisputed aesthetic peak in the history of Chinese tea culture. Building on the tea-boosting traditions of the Tang Dynasty, tea appreciation evolved into a pursuit of ultimate "elegance and refinement", elevating tea drinking from a daily routine to a lifestyle combining philosophical contemplation and artistic expression.
The dominant tea-making method of the Song Dynasty was the "whisked tea method (Diancha)". Compressed tea cakes were first roasted and ground into fine powder, then placed in a tea bowl. Hot water was poured over the powder, and the mixture was repeatedly whisked with a special tea whisk until the tea liquor and air were fully integrated, forming a layer of fine, dense white foam on the surface. This process required not only precise technique but also strict standards for tea ware, water temperature, and the environment.
The Diancha method gave rise to the national pastime of "tea competitions (Doucha)", enjoyed by everyone from imperial nobles and literati to common townsfolk. The judging criteria were extremely rigorous: pure white tea liquor was considered the highest quality, followed by off-white, grayish-white, with yellowish-white as the lowest grade. The foam was judged by its persistence, with foam that clung to the bowl and lasted longer deemed superior. Tea competitions were not only a test of tea quality, water quality and tea-making skills but also a concentrated reflection of the aesthetic tastes and life attitudes of the Song people.
Emperor Huizong of the Song Dynasty, Zhao Ji, personally wrote the Treatise on Tea from Daguan Period, using imperial authority to push the art of Diancha to its historical peak. The book systematically and elaborately discussed tea origins, harvesting, processing, tea ware, and whisking techniques, becoming an authoritative guide to Song Dynasty tea culture. Building on the Diancha tradition, the Song Dynasty also gave birth to "tea play art (Chabaixi)", known as "water painting". Tea artists used water to create patterns such as flowers, birds, landscapes, and figures on the tea foam, perfectly blending tea art and painting. This unique art form left behind many precious cultural treasures, preserving the exquisite romance of Song Dynasty tea culture to this day.
