Experiencing Tea - Wrong Fu Cha

„Pos­si­bly the most neb­u­lous of tea’s qual­i­ties are ascribed to 茶氣 [chá qì] — a tea’s “energy.” Most read­ers will prob­a­bly be famil­iar with at least some of the wide rang­ing effects it is attrib­uted with. Prac­ti­cally any phys­i­cal or men­tal stim­u­lus out­side of the mouth, nose, and throat falls into the realm of cha qi.“

„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.“
