Discover. Connect. Enhance.
uncrack is the data-driven green coffee auction built by EGGSTONE, a data-science and AI company. Behind every lot stands the Uncrack Engine: one connected intelligence spanning green chemistry, roasted profiles and the roast itself. See the unseen, powered by data and intelligence.
Not a scoring tool — an intelligence. The Engine is built on years of paired measurements across green beans, roasted beans and the roasting process, one of the deepest coffee databases of its kind, resolved by machine-learning models into evidence you can bid on. Every auction feeds it; every season it predicts sharper.
An auction exists to find differentiated quality — and differentiated quality is the value.
The industry finds it with sensory: five senses and experience. It works — and it isn’t enough. A score can’t say which lot has the better acidity, texture, balance or potential. It can’t explain why the difference happened, prove it, or reproduce it next season.
In a market where 0.13 points multiplies a price, the missing information is the whole game. So we built the auction on information sensory scores cannot see.
Best of Panama 2025, Geisha Washed — 94.63 drew 658 bids at $6,105/kg; 94.50 drew 148 at $2,040/kg.
CGLE V-auction 2025 — 94.25 hammered 13× higher than 94.00, from the same region.
#apple #pear vs #apple #chestnut-honey. Which do you bid on, and why? The score alone can’t say.
Scores vary by person, culture and region — nothing anchors them at the green stage.
Chemical composition reveals true value with clear, measurable proof.
Exceptional lots remain disconnected, undiscovered, undervalued.
Objective data bridges origin to the world — trusted, traceable, traded on one floor.
Value stays vague; entry barriers stay high; many lots are never seen.
Price driven by data, aligned with quality, built for long-term growth.
Data discovers the hidden value.
One NIR scan resolves a green lot into 16 named components, six taste axes and plain quality signals — its potential read objectively, before the first roast.
Bridge origin to the world.
One live floor, one shared timeline. A producer in Santa Bárbara and a roaster in Berlin bid on the same evidence — anonymous paddles, exporter-settled.
Proof raises price.
Visualizing a coffee’s strengths with data enhances its value. Every farm gets its analysis back, win or lose — and the evidence compounds each season.
The next great coffees aren’t just found — they’re nurtured. Both pilots ran with Busan Technopark under a Korean national program, with IHCAFE at origin.
Honduras Discovery: Next Gen Auction
Next-generation producers across Honduras, discovered and put on the global stage — value proven in numbers, from green chemistry to precision roasting.
Colombia Frontier: Science of Nature Auction
With Colors of Nature — a farm at the top that refuses to settle — experimental microbial-fermentation lots, analyzed by the engine and put before the market.
One submission turns your coffee into visible coffee.
The engine reads its chemistry — you get the full report, win or lose.
Your lot is introduced with its evidence attached.
Buyers worldwide bid on the proof; it sells at the price it deserves.
Create an account, accept the terms, request samples.
Components, taste potential, quality signals — set your ceiling.
One shared timeline, tiered increments, anti-snipe close.
Confirmed at the hammer; the exporter ships and settles direct.
Won on value, not reflexes.
A washed Geisha at $92.50/kg. Three teams watch the same number. A bid lands in the final minute — the clock resets five. No sniping, no backroom. Buyers, the same evidence, and a price discovered in the open.
Great coffee isn’t found.
It’s proven.
31 lots are open right now. Read the evidence, then bid.
