Puer Tea Glossary - Zhi Zheng Tea Shop

„cha yi; 茶仪 - Tea ceremony. Not generally used to refer to the daily habit of tea making and drinking. Most habitual tea drinkers would be unlikely to use this term in reference to their tea-making activities. Not common parlance in Yunnan tea making circles“

„Bitterness
Broad leaf variety (Sinenesis Assamica) is high in natural constituents; polyphenols, caffeine,theine, etc. A particularly bitter flavour is a special characteristic of the Broad leaf variety, but it is important that it transforms quickly and does not linger. This is a mark of good quality Puer. NB there is a sub-variety in Yunnan - Var. ku cha which has different characteristics and does not transform in the same way.“
