Provenance documentation standards

The quiet certainty of a documented cake

Light seeps through the narrow window of the aging vault, falling across a stack of white cotton cake wrappers. At the centre of the room, Fang Ting — senior tea expert for oolong, green, and pu-erh varieties — turns a cake of 2018 shēng chá (生茶) slowly, matching the pressed neifei against the photograph in the provenance file. A single note of camphor rises in the still air.

Provenance is more than paperwork; it is the story of a tea’s journey from leaf to cake, from garden to cup. For collectors, that story determines value and authenticity. The documentation standards we have built at tea.money eschew reputation alone — they record every transfer of custody, every environmental shift, every expert evaluation, assembling a verifiable trail that spans years. The sound of a ballpoint pen scratching across a ledger line marks each change of hands, each carrier’s signature a link in an unbroken chain.

The core of the standard is the provenance packet: a chain-of-custody ledger, a photographic record with timestamps and geotags, quarterly storage logs, and a wet-leaf evaluation report. The photographs begin in the garden — a farmer holding a freshly plucked bud beside a serialised card, taken on a smartphone and uploaded within the hour. At the pressing factory, a second image captures the stone press in mid-arc, the cake still warm and yielding. The cold, dry air of the vault is the final environment, where sensors log temperature and humidity every fifteen minutes. Before a cake even appears on shop.thetea.app, its documentation packet is complete and verifiable, linked from the listing for any prospective buyer to inspect.

The wet-leaf evaluation, drawn from the protocols refined at tea.school, transforms the sensory into the measurable. Panelists weigh 5 grams of tea, note the colour of the liquor against a standardised scale, and score the mouthfeel on a ten-point matrix. Fang Ting helped shape these protocols after observing inconsistencies in private documentation. ‘A single missing month of storage data can alter the perceived trajectory of a cake,’ she explains, tapping a humidity log with her fingertip — the paper gives a soft, dry sound.

Every documentation packet is digitised and mirrored on puerh.app, where members can trace their cake’s timeline and cross-reference it with the broader community archive. In Rotterdam, a collector can compare notes with a counterpart in Kunming through the shared provenance feed. A QR code etched into the inner ticket of the cake wrapper links directly to the immutable record, so authenticity is never in doubt. The weight of the wrapper in your hand — thick, fibrous, printed with the cake’s serial number — serves as a tangible reminder of the digital chain behind it.

At quarterly open-vault sessions — listed on tea.events — you can sit with a resident master, inspect the physical logs, and taste a sample pulled from the same tong your cake rests in. The taste of a well-aged pu-erh, with its deep notes of forest floor, camphor, and old wood, becomes the ultimate verification. These sessions, held in the very vault where your cake breathes, allow you to experience the intersection of documentation and sensory truth.

The standards are updated as the team learns — new photo specifications, additional evaluative criteria, or better sensor technology — without retroactive alteration. Once a cake’s record is sealed for a given period, it remains an immutable snapshot. That commitment to transparency, built into the architecture of tea.money, turns every vintage cake into a documented asset rather than a leap of faith.

What changes

• Every aged cake purchased through tea.money arrives with a provenance booklet — chain-of-custody ledger, timestamped photographs, and a wet-leaf evaluation signed by a certified expert.

• Storage condition logs are updated quarterly, showing temperature, humidity, and any notable events in the aging vaults.

• A digital copy of the full documentation is archived on puerh.app, verifiable by any member with the cake’s unique identifier.

• The tea.school reference library offers a short course on interpreting wet-leaf evaluation sheets and understanding storage variables.

• Quarterly open-vault sessions, booked through tea.events, let you inspect your cake’s documentation alongside a resident master while tasting a sample.

• A QR code on each cake wrapper links to the immutable provenance record, accessible anytime from your phone.
