Arabica Coffee Varieties Compared: Typica to Geisha

Arabica coffee is one species, Coffea arabica, but it has many varieties, just as wine grapes or apples do. More roasters now print the variety on the bag: Typica, Bourbon, Caturra, SL28, Geisha. This guide compares the varieties you are most likely to see, drawing on the public variety catalogue maintained by World Coffee Research (WCR), so you can tell what each name suggests and how much weight to give it.

Why variety matters, and why it is only part of the story

Variety sets a plant's potential: its yield, its size, its resistance to disease and the range of flavours it can produce. But the same variety grown at a different altitude, processed differently, or roasted differently can taste very different. Think of variety as one important ingredient, alongside place and processing. Our guides on how altitude affects flavor and washed vs natural vs honey processing cover the other two.

The two great lineages: Typica and Bourbon

Most traditional arabica in Latin America descends from a small number of plants taken out of Yemen centuries ago, which gave rise to two main groups.

Typica is one of the most culturally and genetically important arabica varieties. WCR describes it as having high quality potential but low yields and susceptibility to major diseases such as coffee leaf rust. The Blue Mountain variety grown in Jamaica is a Typica selection; Kona's traditional plantings are Typica as well. Typica-family coffees are often associated with a clean, sweet, balanced cup.

Bourbon takes its name from the island of Bourbon, now Réunion, where French colonists planted seeds from Yemen in the 18th century. It typically yields more than Typica and is also prized for quality, often described as sweet with good complexity. Red, yellow and pink Bourbon are colour forms of the ripe cherry.

Compact and hybrid varieties

Caturra is a natural mutation of Bourbon discovered in Brazil, with a compact, dwarf growth habit that allows denser planting and higher yields. It became a mainstay in Colombia and Central America.

Catuai was bred in Brazil by crossing Mundo Novo with Caturra. It is compact and productive and widely grown across Latin America.

Castillo and other rust-resistant varieties were developed by research centres such as Colombia's Cenicafé, using Timor Hybrid parentage to resist leaf rust. They have helped farmers maintain production where rust is a serious threat.

Distinctive specialty varieties

SL28 and SL34 were selected by Scott Agricultural Laboratories in Kenya in the 1930s. SL28 is known for drought tolerance and an exceptional, often blackcurrant-like and bright cup that defines many Kenyan coffees.

Pacamara is a cross between Pacas (a Bourbon mutation) and Maragogipe (a Typica mutation with very large beans), developed in El Salvador. Its beans are large, and its cup can be bold and complex.

Geisha (Gesha) originated in coffee collected in Ethiopia and became famous in Panama in the 2000s. WCR notes very high quality potential at high altitude and relatively low yields. Its cup is usually floral and tea-like. See Geisha vs Blue Mountain for a full comparison.

Ethiopian landraces (often labelled "heirloom") are the enormous genetic diversity of arabica growing in its homeland. Many are local selections that are not formally named on the bag. They produce the floral, citrus and berry profiles Ethiopia is known for.

Side-by-side summary

These descriptions are tendencies drawn from how the varieties are commonly described, not promises; every farm and harvest is different.

Arabica versus robusta

All of the varieties above belong to Coffea arabica. The other major commercial species is Coffea canephora, usually called robusta. Robusta plants are generally more vigorous and disease-tolerant and grow at lower elevations, and robusta beans typically contain more caffeine than arabica. In the cup, robusta is usually heavier and more bitter, which is why it appears mainly in some espresso blends and instant coffee. When a bag says 100 percent arabica, it tells you the species, but not the variety, the origin or the quality, so it is only a starting point.

Why new varieties keep appearing

Coffee faces pressure from diseases such as leaf rust and from changing climate conditions. Organisations such as World Coffee Research work with national research institutes to breed and test varieties that combine disease resistance and resilience with good cup quality, including F1 hybrids created by crossing distinct parents. You may start to see some of these names on bags in the coming years. They do not replace the classics, but they help keep high-quality coffee viable for farmers.

How to use variety when you buy

• If you love balance and smoothness, look for Typica-family coffees, including Jamaica Blue Mountain, and Bourbon.
• If you love bright, juicy acidity, look for SL28 and SL34 from Kenya, or Caturra from high-altitude farms.
• If you love floral aromatics, look for Geisha or Ethiopian landraces.
• If the variety is not listed, do not worry; origin, process and roast date tell you more. Our coffee label guide explains each field.

To turn these preferences into a shopping list, read how to choose coffee beans for your taste. To taste a classic Typica-family coffee for yourself, try our Jamaica Blue Mountain whole beans and compare them with a coffee you already know, using tasting notes to describe the difference.
