Puer Tea Glossary - Zhi Zheng Tea Shop

„kou gan; 口感 - Literally mouth-feeling. Dictionary definitions vary between mouth-feel referring strictly to textural character - i.e. 质地/zhi di, others to a broader definition of flavour. In tea drinking it is largely referring to the former, but cannot be easily separated from other gustatory and olfactory sensations.“

„Ripened or aged raw pu-erh has occasionally been mistakenly categorised as a subcategory of black tea due to the dark red colour of its leaves and liquor. However, pu-erh in both its ripened and aged forms has undergone secondary oxidization and fermentation caused both by organisms growing in the tea and free-radical oxidation, thus making it a unique type of tea. This divergence in production style not only makes the flavour and texture of pu-erh tea different but also results in a rather different chemical makeup to resulting brewed liquor.“
