Tea-Cultivation to Consumption.

TEA - CULTIVATION to CONSUMPTION. Edited by K C Willson and M N Clifford. 769 pages with index. Price: 78.00 [pounds]. (UK: Chapman and Hall)

Some twentyone authors have been involved in creating this text which covers the tea business. Tea is an unusual crop is that it is bush propagated then harvested manually, processed and marketed in rather a unique fashion. The book has been planned to look at the whole tea business step by step. Each aspect of tea production is covered, so the book serves as a textbook on tea production. As some readers will know, this industry has tended to develop along its own lines and much of the research effort has been funded by the tea companies themselves. Nowadays the scope of that research is being widened and more fundamental investigations are now being undertaken.

The twentyone chapters explain the scope of the text very well and they run: Historical introduction; Botanical classification of tea; Selection and breeding of tea; Climate, weather and the yield of tea; Soils; Tea crop physiology; Field operations - 1; Field operations - 2; Mineral nutrition and fertilizers; Pest and disease control in Africa; Disease control in Asia; Pest control in Asia; Green and semi fermented teas; Production of black tea; Speciality and herbal teas; Instant tea; The chemistry and biochemistry of black tea production - the non volatiles; Tea aroma; The world trade in tea; Impurities, quality standards and legislation; and Physiological and clinical effects of tea.

The historical section at the beginning of the book traces at least 2000 years of tea as grown in China. It is one of our older crops and yet it is taken for granted as a moderately cheap beverage in this part of the world. It seems to have few vices or side effects, so that even over-indulgence is not a problem. In reality, it is very big business and many people around the world depend on it for their livelihood. This text is up-to-date and will be of interest to all those involved in the tea business in the widest sense.
