"Excelso" is a grading term for exportable coffee from Colombia, not related to variety or cupping profile. EP (European Preparation) specifies that the raw beans are all hand sorted to remove any defective beans and foreign material. This coffee beans are large, but slightly smaller than Supremo coffee beans. Excelso coffee beans are a screen size of 15-16, versus Supremo beans which are sized on screen 17. We love it as a dark roast, but you can request a medium roast when ordering if you like.
