Coffee Basics: Three Major Coffee Bean Varieties - Flavor Differences Between Typica, Bourbon, Geisha, Catuai, Catimor

Major Coffee Varieties

Sixty-six countries around the world currently grow coffee, and the crop falls mainly into three categories: Arabica, Robusta, and Liberica. Of these, Arabica and Robusta are by far the most common.

Arabica has a large number of varieties, and most of them deliver clean, high-quality flavors, which is why the specialty coffees on the market are all Arabica. Arabica plants are generally weaker against disease and pests and are demanding about their environment, so they need careful cultivation. Yields are lower, and the species accounts for roughly 30% of global coffee production.

Robusta has fewer varieties, and most are strongly bitter, which makes them a common choice for instant coffee or for drinking with plenty of sugar and milk. Robusta is extremely resistant to disease and pests, needs little from its environment, and requires minimal maintenance. Yields are higher, and it accounts for nearly 70% of global coffee production.

The beans we hear about most often, such as Typica, Bourbon, Gesha, Caturra, and Catuai, are all Arabica varieties, yet their flavors and textures differ markedly.

Arabica Varieties

Typica

Typica originates from southeastern Ethiopia and Sudan and is one of the oldest coffee varieties within the Arabica species. Its top leaves are reddish-brown, which earned it the nickname red-topped coffee. Most of the Arabica varieties we see today descend from Typica.

Through observation and cupping, FrontStreet Coffee has found that Typica beans are oval, with a slender, full body and a clean taste marked by a subtle, pure flavor.

Bourbon

Bourbon is a natural mutation of Typica, and its most noticeable change is in the bean itself, which went from Typica's long shape to a round one. Bourbon was first cultivated on Réunion Island, which was called Bourbon Island before 1789, and the variety took its name from there.

Through observation and cupping, FrontStreet Coffee has found that Bourbon beans are short and round, with a thick body, a smooth taste, and prominent sweetness.

Gesha/Geisha

Gesha/Geisha comes from the Gesha forest in Ethiopia. Compared with other varieties, its most striking trait is an extremely low yield. On the tree, the branches show long, widely spaced nodes, which means fewer flowers and fruits overall.

Through observation and cupping, FrontStreet Coffee has found that Gesha beans are slender, with pointed ends and a plump, full middle section.

Caturra

Caturra is a natural mutation of Bourbon. Its branches grow close together and its fruit is smaller than Bourbon's, which allows more fruit to be produced in the same space and greatly increases yield.

Through observation and cupping, FrontStreet Coffee has found that Caturra beans are round and elongated with a curved tail end, offering a bright, clean taste and prominent sweetness.

Catuai

Catuai is an artificially bred hybrid of Caturra and Mundo Novo. It inherits Mundo Novo's high yield, strong disease resistance, and excellent cup quality, alongside Caturra's small size, high-quality acidity, and suitability for sun-dried processing. Because the plant is compact, it can be planted at twice the usual density.

Through observation and cupping, FrontStreet Coffee has found that Catuai beans are oval and flat with a fairly slender tail end, offering gentle acidity, a clean taste, and rich fruity aromas.

FrontStreet Coffee Recommendation

If you want to taste why Gesha/Geisha became the most famous variety on this list, FrontStreet Boquete Geisha is a friendly place to begin. Grown in the Boquete region of Panama at about 1,600 meters, where volcanic ash soil is rich in nutrients, it is an estate-level entry Geisha that cups with the variety's signature jasmine florals, green tea, honey, citrus, and orange.

For a step up, FrontStreet Emerald Green Label Geisha is sold under the name "Private Collection." It is a blend of lots from several plots rather than a single small plot, and it focuses on the hallmark Emerald Geisha flavor from high altitude. Because it does not chase plot-level detail, it offers considerably better value than the top tier, and it remains an excellent way to drink true Emerald Geisha.

And if you want Geisha's floral-fruity character in an easygoing, everyday cup, FrontStreet Strawberry Candy blends a honey-processed coffee from Costa Rica with a washed Geisha from Panama and roasts it to medium, giving delicate florals and sweet fruit that work in a pour-over, a moka pot, an espresso machine, or a cold brew.
