Overall Impression:

The sample consisted of Kenyan Robusta green coffee beans. Despite exhibiting uniformity in size, this Robusta coffee contained a significant amount of low-density "floater" beans. These beans, due to their lower density, appeared as Quakes after roasting. Despite this drawback, the coffee maintained good commercial quality relative to other Robusta beans.
