Pu-erh tea

„Pu-erh tea processing, although straightforward, is complicated by the fact that the tea itself falls into two distinct categories: the "raw" Sheng Cha and the "ripe" Shou Cha. All types of pu-erh tea are created from máochá (毛茶), a mostly unoxidized green tea processed from a "large leaf" variety of Camellia sinensis (C. sinensis assamica) found in the mountains of southern Yunnan.“

„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.“
