By which two methods are coffee beans typically sorted?

Coffee beans are typically sorted by color and density because these factors significantly influence the quality and pricing of the beans. Sorting by color helps to identify any defects or unripe beans, as properly processed coffee beans should display a consistent color. Uniformity in color indicates better quality and ensures a more uniform roast, which is essential for achieving the desired flavor profile in the final brew.

Density is also a crucial sorting criterion because denser beans tend to have more flavor complexity and are considered higher quality. Denser beans are often found at higher altitudes where coffee grows, leading to slower maturation and a more developed flavor. Sorting beans by these characteristics allows producers to selectively highlight the best beans while maintaining quality standards in their products.
