A scholar, calligrapher and tea authority
Cai Xiang (1012–1067) was a Northern Song official and celebrated calligrapher. His Record of Tea, or Chalu, was written in the mid-eleventh century and became one of the most influential tea texts after Lu Yu's Classic of Tea.
The book did not try to tell the entire history of tea. It concentrated on the practical signs of a good bowl: tea colour, aroma, taste, storage, grinding, water, fire and utensils.
Why Jian bowls mattered
Cai praised dark bowls from Jian'an because their colour made pale whipped tea easier to judge. The vessel was therefore part of the evaluation system, not an ornamental extra.
His writing also shows how tribute tea, court taste and regional craftsmanship reinforced one another. A highly valued tea created demand for specialised bowls, and the bowls helped define what connoisseurs expected from the tea.
From opinion to standard
The importance of Chalu lies in its discipline. Cai Xiang did not simply say that a tea was excellent; he described observable characteristics and preparation conditions. That approach remains central to professional tea buying today.
