From hedonic noise to disciplined evaluation
Pu’er tasting sits in an awkward place between sensory science and connoisseurship. On one side stands GB/T 23776-2018, China’s standardised tea evaluation protocol — 3 g of leaf, 150 ml of boiling water, five-minute infusion, scored on appearance, aroma, liquor, taste and spent leaf. On the other side is the gōngfū table, where the same cake reveals different things across eight or twelve short infusions, and where a senior taster will register cāng wèi (仓味, storage notes), throat depth and qì (气) — categories the standard does not measure. Neither approach alone is sufficient. The articles in this topic try to bridge them.
A working vocabulary for tasting pu’er begins with separating sensations that beginners conflate. Bitterness is a taste, registered on the tongue and (in good young shēng) clearing within seconds. Astringency is a tactile event — the puckering grip of polyphenols binding to salivary proteins, felt across the gums and cheeks. A Lao Banzhang cake from the Bulang mountains in Menghai will be aggressively bitter yet structurally clean; a poorly made roadside blend can be merely astringent and stay that way. Distinguishing these two is the first hurdle. The vocabulary article walks through the canonical pairs: kǔ/sè, shēng jīn/huí gān, hóu yùn/kǒu yùn (throat charm versus mouth charm), and the cāng family of storage descriptors codified by Hong Kong traders from the 1970s onward.
Common defects in pu’er — and what causes them — translates that vocabulary into diagnostics. Sourness from anaerobic compression in humid storage. The flat, cardboard quality of leaf that was pan-fired too hot during shā qīng (杀青), denaturing enzymes the cake needs to age. The metallic edge of over-pressed centres that never breathed. The wet-basement note that some collectors tolerate and others reject outright. Each defect has a cause in the supply chain, and learning to name them is what protects a buyer from a USD 400 mistake.
The payoff is the third article, evaluating an unknown cake — a 7-step protocol. It assumes you are handed a wrapper with a plausible-looking neifei, no provenance, and a price that demands a decision. The protocol moves from dry-leaf inspection through rinse aroma, first three infusions, mid-session structure, late-session decay, wet-leaf forensics, and finally a written verdict. It is the same logic a Vinous critic applies to an unlabelled Burgundy, adapted to a tea that may be anywhere from two to forty years old.
This kind of evaluation matured slowly. The 1995 Taiwanese collector boom forced the first generation of pu’er vocabulary into print — Deng Shihai’s Pǔ’ěr Chá (普洱茶, 1995) being the obvious landmark — and the subsequent Yunnan price spike of 2007 made disciplined tasting an economic necessity rather than a hobby. Today the standard reference points are spread across journals, vendor cuppings, and the slow accumulation of session notes in serious drinkers’ notebooks.
Readers building their palate alongside these articles will benefit from structured study at tea.school and the cupping events listed on tea.events. Vocabulary without repetition stays inert; the only cure is to taste, name, and taste again.
