A century-old cake sells for HK$3.5 m while the factory tea that the speculative market actually trades has lost four-fifths of its value since 2021; the asset appreciates only if stored correctly for decades and is the most counterfeited tea in the world.1 2Med

First entry. L&H Auction's autumn 2025 sale carried the first complete seven-cake stack of Red Mark Song Pin Hao offered at auction, following its HK$3.5 m hammer for a single cake in spring 2024; Dayi's Xuan Yuan series, the speculative benchmark, had fallen to 380,000 yuan a unit by mid-2025 from 1.88 m in 2021.1 2
Two markets share a name. Antique and state-era cakes are valued by a handful of Hong Kong specialists on wrapper, ticket, compression and taste, trade a few dozen lots a year, and are forged at every tier. Modern Dayi factory tea has daily quoted prices on the Donghe platform and a wholesale market at Fangcun, which looks like price discovery until one notices that 95% of it is bought to store, not drink, and that the quotes have halved twice in twenty years. Custody is the asset: a cake stored too dry does not age, too wet is ruined, and the storage history cannot be verified from the outside. Exit for anything but current Dayi is a consignment into a thin Hong Kong sale. Title is simple; everything else is not.
The Σ grade is ΣΟΦΙΑ's opinion of how practical the asset is to hold. Not a view on return. How it is judged →
The one collectible that is literally consumed in the tasting, and whose value depends on a biological process the owner must manage for decades. This page covers the record book for antique cakes, the factory-tea speculation that is the real market by volume, the tiers and what the wrappers mean, storage and forgery, and what to watch. No prices are carried as live values.
Five pre-war tea houses and the 1950s state marks hold every record.

Sotheby's held its first dedicated tea sale in December 2021 with a 1900s Chen Yun Hao estimated at HK$900,000–1.2 m, which marks the point at which the category reached the international houses; Poly and L&H had been running dedicated pu-erh sales for a decade. Essence of Tea's observation is the structural one: every tier below is priced as a fraction of the tier above, so a record for Fu Yuan Chang reprices Song Pin Hao, which reprices Red Mark, which reprices the 1980s cakes.5 7 Med
Dayi as a quoted security, and what happens to it.
Menghai Tea Factory (state factory No. 2 until privatised in 2004; brand Dayi, TAETEA) produces the 7542 and 7572 recipes that defined the category and the limited series that the speculative market trades. New releases are allocated to franchise stores at a list price; they change hands at Fangcun in Guangzhou at a multiple of it on the day of release, and the Donghe platform quotes bid and offer by batch like a stock screen. A 2020 7542 reached about 50,000 yuan a jian (42 cakes) and was at 29,000 by early 2024; the Xuan Yuan series went from 70,000 yuan a unit in 2017 to 1.88 m in 2021, 1.08 m in early 2023 and 380,000 in June 2025.2 8 High

The identification column is the valuation. A Red Mark is a Red Mark because of the colour of one character on a wrapper that can be reproduced; a Hao Ji cake has no wrapper at all and is identified by a paper ticket pressed into the leaf. Taste confirms, but only after the cake is broken, which is why the Hong Kong specialists (Sun Sing Tea's Henry Yeung consulted on Sotheby's first sale) are the market's certificate, and why their opinion is the price.7 Med
The asset is made by the holder, and faked by everyone else.
| Risk | Mechanism | Mitigation |
|---|---|---|
| Storage | Raw pu-erh ages by slow microbial and oxidative change that needs humidity and warmth; Hong Kong "traditional" storage ages fast and can go mouldy; Kunming dry storage barely ages at all; the two are different products at thirty years | Declared storage history from a known warehouse; buy stacks that have stayed together; accept that the history is unverifiable |
| Forgery | Dayi is the most counterfeited tea brand in the world; antique wrappers and tickets are reproduced; CNNP sold its name and wrappers to any buyer after privatisation | Specialist authentication; auction-house guarantee; provenance from a named Hong Kong tea house |
| Market concentration | Prices set by a few hundred storers in Guangdong and Hong Kong; gift-giving demand politically exposed | None; this is the market |
| Consumption | Every tasting removes tea; a broken cake is worth less than a whole one | Trade whole cakes and complete stacks (tong of 7) |
| Exit outside China | Western auction interest is nascent; buyers are in Hong Kong, Guangzhou, Taipei | Consign in Hong Kong; expect 15–25% in fees |
Title passes with the cake and the market has no registry, which makes transfer trivial and provenance impossible: there is no equivalent of a bonded warehouse ledger or an auction-house condition report that survives a change of hands. The nearest analogue on this site is whisky casks, with the difference that a cask at least has a warehousekeeper. Hyp
