Does a higher screen size always mean better coffee?
No, a higher does not guarantee better coffee. simply indicates the physical size of the bean, which is used for sorting and consistency during roasting. While larger beans are often associated with higher quality, flavor is determined by factors like , variety, and processing, not just bean size.

In the world of coffee grading, is a common metric used to categorize . It refers to the diameter of the holes in the sorting screens used to separate beans by size, typically measured in 1/64th of an inch. For example, a 'Screen 18' bean is larger than a 'Screen 14' bean. While it is true that many high-quality specialty coffees are large, assuming that size equals quality is a common misconception.
Historically, larger beans were often preferred because they were thought to be more mature and uniform, which makes the roasting process much easier. When beans are of a similar size, they absorb heat at a more consistent rate, leading to a more even roast. This is why many commercial buyers prioritize —it simplifies production and ensures a consistent product on the shelf.
However, flavor is a complex result of , , and processing. A smaller bean grown at a very high , where the cooler temperatures cause the to mature slowly, will often have a much more complex and desirable flavor profile than a large bean grown at a lower . In fact, some of the most prized varieties, such as the , are naturally smaller and rounder, yet they are highly sought after for their unique, concentrated flavor.
Focusing too heavily on can also lead to the exclusion of excellent coffees. Many specialty roasters now prioritize 'microlots' and specific varieties over standardized grading metrics. They look for cup quality—the actual sensory experience—rather than the physical dimensions of the bean. A coffee that scores high on a table is a better coffee, regardless of whether the beans are large or small.
In practice, is a useful tool for roasters to manage their heat application, but it should never be the sole indicator of quality for a consumer. When buying coffee, look for information about the origin, the variety, and the processing method. These details will tell you far more about what to expect in your cup than the size of the beans ever could.
