Original roaster or listing source

External customer, cafe, marketplace, and class ratings are not comparable measures of the quality of an individual coffee. We do not convert them into original tasting scores or brand-wide star ratings. Our independent reviews are published separately after a coffee has actually been brewed and evaluated.
