What is the difference between Supremo and Excelso?

In the world of Colombian coffee, the terms Supremo and Excelso are often misunderstood as indicators of quality or flavor. In reality, they are physical classification systems used to sort green coffee beans by size after they have been harvested and processed. Both grades can originate from the same coffee tree, but they are separated during the milling process using grading screens.

Supremo is the designation for the largest beans, typically those that remain on a screen size of 17 or 18. Because these beans are larger and more uniform, they have historically been marketed as the flagship grade for Colombian exports. Excelso, by contrast, consists of slightly smaller beans, usually falling into the screen 15 or 16 range. While Supremo is often sold at a premium due to its size, it is a common misconception that it is inherently 'better' than Excelso.

For the consumer, it is important to remember that screen size is not a direct proxy for taste. A well-farmed, carefully processed Excelso lot can easily outperform a mediocre Supremo in a blind cupping session. In the specialty coffee industry, quality is determined by sensory attributes—such as acidity, body, and flavor notes—rather than the physical dimensions of the bean. Many roasters find that Excelso lots offer excellent value and a balanced, classic Colombian profile.

Furthermore, you will often see the term 'EP' (European Preparation) associated with these grades. This is a separate quality standard that indicates the beans have been hand-sorted to remove defects and foreign material. When you see 'Excelso EP' on a bag, it means the coffee has been rigorously cleaned, ensuring a high-quality experience regardless of the bean size. In practice, focus on the roast profile and the specific region of origin rather than just the size grade when choosing your next bag of coffee.
