How Do Arabica Coffee Bean Varieties Look Different?

Almost all single-origin coffee falls under the Arabica species, yet arabica coffee bean varieties differ in bean shape, grain size, and the form of the center line. Varieties such as Typica, Bourbon, SL28, SL34, Caturra, Catuai, and Geisha can be told apart by careful visual observation and memorized traits rather than innate talent.

At Gesha Village, the varieties known as Gori Gesha and Gesha 1931 were selected by combining plant morphology, bean shape, and cupping flavor, without genetic testing. The estate owner traced historical records to the Gori Gesha forest, where British collectors were thought to have taken seeds, and judged the samples closely similar to panama geisha.

Have you ever met a coffee expert who can pick up a bean, glance at it, and immediately tell you its variety and origin? In fact, this isn't an innate gift—it's built on careful observation and memory of the visual characteristics of Arabica varieties. Although almost all the single-origin beans we drink daily belong to the Arabica species, there are subtle differences among varieties like Typica, Bourbon, SL28, SL34, Caturra, Catuai, and Geisha in bean shape, grain size, and even the form of the center line. This article will compare the visual traits of these varieties one by one using real photos, helping you build a visual memory system for "identifying varieties by looking at beans." At the same time, it will take you through how Gesha Village traces the story of Gori Gesha and Gesha 1931 through plant morphology, bean shape, and cupping flavors.

I wonder if any coffee enthusiasts have noticed that there are always some "masters" around them who can accurately state information like variety and origin just by glancing at coffee beans, leaving people deeply impressed. How exactly did they develop this skill?

Actually, the single-origin coffees we usually drink are basically all from the Arabica species, but the visual differences among varieties within Arabica are not small. If you want to judge variety just by the look of the beans, you have to calm down and observe each variety's beans one by one, identify their characteristics, and commit them to memory. Isn't this exactly the same as practicing coffee sensory skills?

Typica

Bourbon

SL28&SL34

Caturra

Catuai

Geisha

For example, the varieties known at Gesha Village as Gori Gesha and Gesha 1931 were identified after the estate owner consulted historical records and located a place called the Gori Gesha forest. He speculated that the British had collected and taken Geisha seeds from there back then, so they also went to that location to sample, and ultimately selected out Gesha 1931. It is worth noting that this selection process did not rely on genetic testing, but on comprehensive judgment based on plant morphology, bean shape, and cupping flavor. From the samples, they concluded that this variety is very similar to Panama Geisha.
