4.1 Tea

Objectives

  • To prepare various teas using loose tea, a tea ball, or tea bags.
  • To describe differences in appearance and flavor of various types of tea:  black, oolong, green, flower, and spiced.
  • To identify the factors affecting the optimum extraction and retention of tea constituents in the prepared beverage:  tea quality, type and temperature of water, material of teapot, and preparation techniques.

General directions for preparation of teas:

  1. Use a clean teapot.  Preheat by filling it with boiling water.
  2. Measure freshly drawn cold water. Heat just to boiling.  As soon as measured water reaches boiling, drain the preheated teapot; place tea leaves in pot; add the freshly boiled water.
  3. Cover pot and steep appropriate length of time for the tea used.  Remove tea bag or tea ball, or strain out tea leaves.
  4. For evaluation, serve tea in pot in which it was prepared.  (If a ceramic pot was used, display a sample of tea in a small clear glass beaker.)
