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.“

„Some more obvi­ous man­i­fes­ta­tions of cha qi are a heat­ing or cool­ing of the extrem­i­ties (eg, sweaty palms when drink­ing a ‘warm­ing’ tea like aged puerh or heav­ily roasted oolong), a flush­ing of the face, or a mea­sur­able change in mood. In a small group, tea can either lead to deep con­ver­sa­tion, giddy laugh­ter, or con­tem­pla­tive silence.“
