A practical manual for dealers and consumers outlines tea classification and descriptive qualities, systematic methods for tasting and selecting leaves, and simple tests to detect adulteration. It argues for skillful blending of complementary varieties to produce fuller-bodied, more aromatic infusions at moderate cost, and explains experimental techniques for composing stable house blends. The work also covers proper storage, selling practices and preparation to preserve flavor and value, emphasizing hands-on trials and proportioning so grocers can reliably meet local tastes while maintaining quality and profit.
