When this book came almost 25 years ago, it quickly became a reference work and I have even seen Chinese tea merchants use. The first half is perhaps not so remarkable, it takes up the history of tea culture and some mandatory things like chemistry, ceramics and health effects.
The book’s strength is the last 60 pages that take up no less than 50 different more or less famous Chinese teas. After 25 year much of the information is outdated. The China Tea Import and Export Corporation lost its role, but if you ignore this, it is still one of the best books written about Chinese tea, especially in English.
