This is a 15/16 screen roasted to a rich full city. Excelso just means the bean is a little smaller in size then the Colombian Supremo. The characteristics of the Excelso are very similar to that of the Supremo Bean. All of our Colombians are European Prep which have fall less defects then (American Process) and produce a much cleaner, more refined brew. We source our Colombian Excelso from the regions of Huila, Medellin, and Bucaramanga.
