What Is the Cup of Excellence Coffee Competition?
For decades, countless exceptional coffees were lost in bulk blends, ruined by poor processing, or sold at unfair prices simply because no one knew they existed—or who grew them. Great beans grown on remote farms often fetched commodity rates, while buyers stumbled upon quality mostly by chance.
The solution began in 1999: the Cup of Excellence (COE), a competition and auction that identifies and rewards the world’s top-scoring single-origin coffees with transparent, premium pricing.
What Is the Cup of Excellence?
The Cup of Excellence (COE) is an international competition and auction series that discovers, promotes, and sells the highest-quality single-origin coffees each year. Run by the nonprofit Alliance for Coffee Excellence (ACE), COE uses rigorous blind cupping to rank entries, with only the top-scoring lots offered to global buyers via transparent online auctions. The program highlights exceptional producers and connects them directly with roasters seeking premium beans.
Why COE Was Created
Before COE, many outstanding coffees were either blended away or mishandled post-harvest—lost to poor processing, bad roasting, or anonymous bulk sales. Farmers had no way to prove their beans’ quality or earn fair prices, and buyers had no reliable way to find them. The system treated all coffee as a generic commodity.
In 1999, the first COE competition in Brazil changed that. By separating top lots through expert cupping and selling them via open auction, the event proved that exceptional coffees could command fair prices—and that farmers deserved recognition. This model then spread globally.
How COE Works: From Cupping to Auction
The COE process is meticulous. Each year, the competition runs in a different producing country. Local farmers submit their best lots for evaluation. These coffees are blind cupped by expert panels using the official COE cupping form. Only those scoring 84 points or higher (raised from 80 in 2004 and again to 85 in 2012) qualify for the auction.
Finalists are cupped again to determine rankings, and the top 30+ lots are auctioned online to roasters worldwide. Since 2010, auction-winning coffees have been vacuum-sealed to preserve freshness. Every COE coffee comes with full traceability, including farm details, processing methods, and cupping scores—empowering roasters to know exactly what they’re buying and where it came from.
