Puer Tea Glossary - Zhi Zheng Tea Shop

„gan; 干 - dry. Sometimes used to describe a certain feeling in the mouth, typically on the tongue or in the throat that is either due to the nature of the tea, or the way it has been processed or stored. Distinct from astringrent. See also 燥/zao“

„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.“
