For centuries, the Chinese and Japanese have been practising the art of the tea ceremony as a way of relaxing the mind, focusing mental energy, social bonding and enjoyment. The Chinese tea ceremony is an intoxicating experience that should be experienced by all those interested in tea culture. The purpose of the tea ceremony is to produce the finest and most aromatic brew from high quality tea (usually Oolong or Pu Erh) and to taste the variations in flavour and finish as the tea changes over many infusions. All of this is done with an artistry of skill, knowledge and movement by the tea master that is poetic and hypnotic and takes years of training and tea knowledge. The art of preparing and making tea is called Cha Dao. The smells and taste are the most important parts of the ceremony, so the rules for making and pouring tea vary depending on the type of leaf used.
Usually an unglazed purple or red clay pot and cups are used, with Yixing (a small area near Shanghai) clay being the most sought after due to the belief that it absorbs any toxins from the tea and water. The pot and cups are unglazed so as to allow the tea oils and resins to be absorbed into the material during the curing process which involves soaking the utensils in tea for a few hours a day for up to a week. After the pot and cups are cured they are ready to be used for the ceremony, however the more they are used the better. Because the clay is cured with one type of tea, it should not really be used to brew other types of tea as this would alter the purity of the flavour.
The quality of the water is absolutely essential to good tea. Distilled or soft water produces a flat brew but hard or tap water can introduce too many other flavours that ruin the tea. The best is filtered water with a pH of 7.9. The temperature depends on the tea but it is always better to brew cooler to prevent the tea from becoming bitter. As a rough guide, white, green and yellow teas should be brewed at about 80 degrees, oolongs at about 85-90 degrees and red and puerh teas at about 90-95 degrees.
