Green coffee auctions

A green coffee auction is a way of pricing unroasted coffee by open bidding rather than negotiation. A lot is cupped blind and scored; if it scores high enough it goes to auction; buyers anywhere in the world then bid on it, usually online, and the price is whatever the last bid was. It is one of the four ways a roaster can buy green coffee — the loud, public one — described alongside spot, forward and direct buying in Green coffee buying.

The reason it matters out of all proportion to its volume is that it is price discovery in the open. Almost every other coffee price is private: a farm-gate figure the producer keeps, an FOB number on an invoice, a differential agreed over email. An auction does the pricing in a room everyone can watch, and publishes the result — lot, score, weight, price, and often the buyer. That is why the numbers this wiki quotes as “records” are nearly all auction numbers: they are the only ones anybody can actually verify.

What the mechanism does

Ordinary commodity coffee is priced against the C market — the New York futures number most of the world’s coffee is valued against (see C-market). A green coffee auction deliberately severs that link. Instead of a base price plus a differential, the price is built entirely from cup quality plus scarcity plus who wants it most. A blind score does the quality half; the bidding does the rest.

The shared machinery, whoever runs it, looks the same:

  1. Producers submit lots, which are cupped blind — the cuppers do not know whose coffee they are scoring — over several rounds, first by a national or in-house jury and then usually by an international one. See SCA cupping protocol and Cupping.
  2. A score threshold gates the auction. Only lots above a set score go through. For Cup of Excellence that bar is 87 points on the 100-point scale.
  3. Buyers taste before they bid. They buy a sample set — a paid box with a few grams of every lot — cup the coffees themselves, and decide what to chase. Pride of Gesha’s 2026 sample set, for instance, cost $750 for 50 g of each coffee.1
  4. The auction is a fixed online window, commonly a couple of days, with live bidding visible to every registered buyer. Records are published afterwards.
  5. The winning money is often several buyers’, not one’s — a Buying consortium splits the lot and the bill. A headline auction price is therefore the combined willingness-to-pay of a small group of specialists, not a market rate.

Three flavours of auction

The same mechanism runs under three different organisers, and the difference is who curates the coffee.

Competition auctions. A quality competition comes first, an association runs it, and the winning lots are auctioned second. Cup of Excellence (run by the Alliance for Coffee Excellence across many countries) and Best of Panama (run by SCAP) are the two landmarks. Anyone in a participating country can enter; the competition, not the producer, decides which lots reach the block.

Curated / invitation auctions. No open national competition — an organiser hand-picks producers or a region and auctions their coffee under its own banner. The twist is that ACE, which runs Cup of Excellence, also runs one of these: its Private Collection Auction (PCA) series, curated sales built with partners such as Qima Coffee (Yemen), El Injerto, Santa Felisa, Long Miles and a Taiwan Coffee collection. PCAs are cupped by an international jury and bid on at ACE’s own auction platform, open to members and non-members.2

Estate / private auctions. A single producer runs its own sale, sets its own terms, and keeps the proceeds without a competition in the middle. Gesha Village (Ethiopia) does this every year as the Pride of Gesha auction — top lots, a paid sample set, a fixed bidding date.1 The model has spread far enough that industry analysts argue these private events are pulling elite buyers away from the competition auctions (see below).

Why it matters

For a producer, winning an auction is the single biggest price event available: a blind score turns into international exposure and a per-pound figure many times the commodity price. For a buyer, the coffee is almost beside the point — the lots are tiny, and the value is in being the roaster who has the coffee nobody else has. That status logic, and why a handful of largely East Asian buyers keep paying the top prices, is Premiumisation. Where the money actually comes from — a group, not a person — is Buying consortium. And the specific price ledgers live on Cup of Excellence records by country and Best of Panama results archive.

Are private auctions killing the competition auctions?

There is a running argument in the trade that estate-run and private auctions are displacing Cup of Excellence: a producer who has already won a “best of” title can carry that label into a private sale — or set up their own — and keep more of a higher price without sharing the stage.3 A 2022 industry analysis frames it bluntly and quotes green-coffee veteran Stephen Hurst — founder of the importer Mercanta and a former CoE board member and judge — that “the Cup of Excellence is relevant in the industry, but not to the consumer.”3

The neat objection to that thesis is that the biggest competition organiser has itself moved into private auctions — ACE’s Private Collection series is exactly the “curated, no open competition” format the private-auction argument describes.2 So the picture is less “private is killing the competition” and more “the competition, the association and the estate are now all running the same mechanism, aimed at the same few dozen buyers.” The debate is real; the clean displacement story is not settled.

To verify

The Lamastus private-auction record. A 2022 analysis reports that Lamastus Family Estates (Panama, the Elida Estate family) sold **7 lb of Geisha for 6,000/lb** at a *privately held* auction, called a record at the time.[^2] This is single-sourced, the article names no buyer, date or lot, and 6,000/lb sits confusingly close to a separately reported $6,034/lb 2023 Panama Geisha figure — the two may be the same sale reported twice, or two different events. Do not quote it as a distinct verified record without an official source.

To verify

Cup of Excellence’s 2023 global statistics. One write-up states that in 2023, across 12 countries, 2,147 lots were entered, 128 reached CoE status (~5.9%), at an average winning score of 88.3 and a median auction price of $42.75/lb FOB.4 These figures come from a single secondary article, not from ACE’s own published results, and could not be confirmed against the official record here. Treat as one source’s summary.

To verify

The “farmers keep ~80% of the sale price” claim. The same write-up says winning producers receive roughly 80% of the final auction price, versus 50–60% in conventional channels.4 This is a single blog figure with no methodology, and auction cost structures (platform fees, export, logistics) vary by organiser and country. Do not state a specific pass-through percentage as fact.
