The facility can be highly mechanized, as in Ethiopia, or very simple, as in Yemen. More where coffee is run across a density table. Less dense seeds are tend to have poor cup character.: Density sorting is a step at the dry mill where coffee is run across a density table. Tilted at an angle, the table vibrates and dense coffee beans travel to the TOP or the highest side of the table, whereas less dense seeds go to the LOWER angle of the table. Less dense seeds are either outright defects, or tend to have poor cup character because they are damaged, or underdeveloped. The density table is often called an Oliver table after one of the older manufacturers.
