When you see  “COE” or “Cup of Excellence” on a bag of coffee, it signals more than just quality. It represents one of the most rigorous and respected competitions in the specialty coffee world.

Cup of Excellence (COE) coffees are award-winning lots selected through a multi-stage blind tasting process. These coffees are recognized as some of the finest produced in their origin for that harvest year, often achieving exceptional prices and global attention.

In this guide, you’ll learn how the Cup of Excellence competition works and what makes these coffees so sought after.

 

What Is Cup of Excellence?

Cup of Excellence is an international coffee competition established in 1999, with its first event held in ブラジル. The program was created to identify outstanding coffees, reward producers fairly, and increase global visibility for coffee-growing regions.

The competition is managed by the Alliance for Coffee Excellence (ACE), a nonprofit organization dedicated to advancing transparency and excellence in the coffee industry.

The Cup of Excellence (COE) online auction system serves as a transparent global platform connecting producers with vetted, professional buyers to secure top-tier coffee lots. This mechanism not only highlights the quality of the coffee but also ensures the majority of proceeds return to the farmers, establishing a trusted market for excellence. 

 

How the Cup of Excellence Competition Works

Cup of Excellence competition is known for its strict, multi-round evaluation system. It employs a strict blind cupping protocol where multiple judges repeatedly score each sample to ensure consistency and fairness. Below is the detailed breakdown of the judging process:

1. Preselection Round

Producers submit their coffee lots, which are coded for blind tasting by an independent auditing firm. Following an ACE Calibration Session to align scoring standards among all cuppers, the National Jury evaluates the entries. Only the top 150 coffees scoring 86 points or higher advance to the next stage.

2. National Jury – Round 2

The advancing coffees are re-coded and blind-tasted by the National Jury. Only the top 90 coffees scoring 86 points or higher move forward.

3. National Jury – Round 3

Coffees are re-coded once again for a second round of blind evaluation by the National Jury. Only the top 40 coffees scoring 86 points or higher qualify for the international stage.

4. International Jury – Rounds 4 & 5

A panel of 16 to 24 international sensory experts (probably including 1–2 local judges) evaluates the remaining lots.

• Cup of Excellence Winners: The top 30 coffees scoring 87 points or higher.
• National Winners: Coffees scoring between 85.00 and 86.99, or those scoring 87+ points that do not place in the top 30.

5. International Jury – Round 6 (The Top 10)

The top 10 coffees from the previous round are re-coded and undergo a final blind cupping to confirm the ultimate scores and official rankings.

6. Awards Ceremony

The rankings are officially announced, and awards are presented to the producers. This is the first moment farmers learn their final standing in the competition.

7. Online Auction

Winning lots are sold through the official COE online auction platform. This transparent bidding system connects producers with vetted, professional buyers and roasters worldwide, ensuring that the majority of the proceeds return to the farmers.

 

5 Key Features of Cup of Excellence Coffee

 

1. Single-Origin, Often Single-Lot

Cup of Excellence coffees are typically single-origin and often come from a single farm or even a specific lot. This allows them to clearly express the unique characteristics of their terroir, shaped by factors such as soil, climate, variety, and processing method.

2. Full Traceability

Each coffee is sold with detailed information, including the producer’s name, farm, variety, processing method, and origin. This level of transparency strengthens trust between buyers and producers and supports long-term relationships.

3. Exceptional Flavor Quality

Only coffees that pass multiple evaluation rounds and achieve high cupping scores are selected. Cup of Excellence winners, scoring 87 points or higher, are considered top-tier specialty coffees.

Flavor profiles vary widely depending on origin and processing, but these coffees are often known for their clarity, complexity, and layered structure, with refined acidity and a long, elegant finish.

4. Verified Quality Through Rigorous Evaluation

The multi-stage blind cupping system minimizes individual bias and reduces the impact of inconsistencies or defects. Repeated evaluations by different juries ensure that only the most outstanding coffees receive recognition.

5. Direct Impact on Coffee Producers

All coffees entered into the competition must be produced within the host country, ensuring authenticity. Winning provides producers with global exposure and access to international buyers.

Through the auction system, farmers can achieve significantly higher prices, helping to strengthen local coffee economies and encourage continued investment in quality.
