“Excelso” is a grading term for coffee exported from Colombia, not related to variety or cupping profile. Excelso coffee beans are large, but slightly smaller than Supremo coffee beans. Colombian coffee is graded before shipment according to bean size. It is possible that Supremo and Excelso coffee beans can be harvested from the same tree, but they are sorted by its size.
