Competitions divided into regions and across Africa will eliminate batches with cup test scores less than 80 points in the preliminaries. TOH will select the highest quality raw beans from each producing area, which will be tested and scored by domestic and international judges based on the standards of the American Fine Coffee Association (SCAA).
