Cai Xiang (蔡襄, 1012–1067) was a Northern Song dynasty official and one of the four great calligraphers of his era who also served as administrator of Fujian’s imperial tea tribute — reforming production to create the famous “Dragon and Phoenix” pressed cake (longfeng tuancha) and documenting his expertise in two tea texts that became classics of Song tea culture.
In-Depth Explanation
Cai Xiang was born in Fujian Province, the same region that produced the most prized teas of the Song dynasty, and his career in the imperial bureaucracy brought him back repeatedly to his home province as an administrator.
The Dragon and Phoenix tribute cakes: Prior to Cai Xiang, Fujian’s tribute tea was produced as small pressed cakes with less sophisticated processing. Cai reorganized the tribute system and introduced the elaborately decorated Dragon and Phoenix pressed cakes (longfeng tuancha 龙凤团茶) — cakes stamped with imperial dragon and phoenix motifs that became the most prized tea objects of the Song court. Getting a single cake as an imperial gift was considered extraordinary honor.
Tea writings:
- Cha Lu (茶录, “Record of Tea,” c. 1049): A short but influential treatise discussing the qualities of tea, the color, aroma, and flavor criteria for evaluation, and the vessels and water best suited to Song diancha (beaten tea, the precursor of matcha). Written as a report to the emperor.
- Pincha Yao Lu (品茶要录, “Notes on Judging Tea”): A companion text on quality assessment.
Diancha context: In the Song dynasty, tea was ground to fine powder and whisked in a bowl with hot water — the same process that eventually became Japanese matcha. Cai Xiang’s texts document the height of this technique in its Chinese context, before it was largely abandoned in China during the Ming dynasty shift to loose-leaf steeping.
Calligrapher: Cai Xiang’s calligraphy was ranked alongside that of Su Dongpo, Huang Tingjian, and Mi Fu — the “four great Song calligraphers” — making him one of the most culturally complete literati figures of the Northern Song era.
History
Cai Xiang served multiple terms as administrator of Fujian’s Jianning tea district during the Northern Song dynasty (960–1127), when diancha — the beating of powdered tea in a bowl with hot water — was at its cultural peak as a court art form and symbol of literati refinement. His organization of the Dragon and Phoenix tribute cake format (circa 1040s) elevated the physical and aesthetic standard of imperial tribute tea. His Cha Lu (茶录, 1049) was written as a formal report to Emperor Renzong documenting the state of tea culture and assessment criteria. Emperor Huizong (r. 1100–1125) brought diancha to its absolute cultural apex, writing the Daguan Chalun (Treatise on Tea). In 1391, the Hongwu Emperor of the Ming dynasty abolished ground tea tribute and mandated loose-leaf steeping, ending diancha in China — but the technique had by then been transmitted to Japan through Zen monasteries, where it was preserved and developed into matcha culture.
Common Misconceptions
- “Cai Xiang invented diancha or matcha techniques.” Diancha predates Cai Xiang — it developed in the Tang-Song transition period. He refined, documented, and elevated the tribute standard; he did not originate the technique.
- “Cha Lu describes how to make tea as we know it today.” It documents Song dynasty diancha using specific equipment (Song jian ware tea bowls, bamboo whisks, ground compressed cakes) different from — but ancestral to — Japanese matcha. Modern matcha preparation is a Japanese adaptation of these same basic principles.
- “The Dragon and Phoenix cakes were commercial products.” They were exclusive imperial tribute gifts. Receiving even a single cake as an imperial presentation was considered an extraordinary honour, not a purchasable commodity.
- “Cai Xiang’s tea culture disappeared entirely in China.” While diancha largely died out after the 1391 edict, there is ongoing scholarly and enthusiast interest in Song tea culture in modern China, and some practitioners explore reconstructed diancha using historically informed methods.
Social Media Sentiment
Cai Xiang appears in growing discussions of Song dynasty tea culture, driven partly by international interest in matcha’s historical origins. Tea history content on Weibo, YouTube, and Instagram occasionally traces matcha’s lineage through Song diancha and Cai Xiang’s Cha Lu. Chinese tea media produces content on Song-era tea culture appreciation and revival. Academic tea history communities cite the Cha Lu as a primary document for understanding pre-Ming tea culture.

Practical Application
- Historical lineage of matcha: Understanding Cai Xiang’s Cha Lu situates modern matcha within a historical continuum — from Tang-dynasty ground tea through Song diancha refinement through Zen transmission to Japan through chadou development. Matcha is not a Japanese invention but a preserved Chinese art.
- Reading the Cha Lu: The Cha Lu is short and accessible in translation. Reading it alongside a cup of matcha provides direct historical connection to Song tea culture aesthetics.
- Song-style diancha exploration: Modern practitioners reconstruct Song diancha using powdered tea, Song-style tenmoku or celadon bowls, and traditional bamboo whisks (chasen) — the same basic tools Cai Xiang documented.
