Cameroon Java Long Beans: Shape, Flavor & Origin

If you’ve ever wondered why some coffee beans look strikingly long and slender compared to the more common round or oval shapes, the answer lies in both genetics and growing conditions. One such example is the Java variety grown in Cameroon’s high-altitude regions—known for its distinct elongated bean shape and unique cup profile.

The Cameroon Java long beans are produced by the Caplami Cooperative at elevations between 1,200–1,800 metres, with a screen size of 18 and above, and are classified as ‘’ (Special Selection). Their most defining physical trait? They are notably long, often graded as 18-screen or ‘long beans’ in trade terms.

What Is the Cameroon Java Variety?

The Java variety found in Cameroon has historical roots tracing back to the early 20th century. It was introduced by German colonists around 1905, reportedly from the same genetic lineage as Typica coffee once cultivated on Java Island and linked to the original Typica that also gave rise to Blue Mountain. This particular Java variety was planted at an agricultural trial station in Dschang, within Cameroon’s Western Highlands, and gradually spread among local farmers who favoured the Typica lineage.

While most of Cameroon’s coffee production—about 80%—is Robusta, destined mainly for export to Germany and France, the remaining 20% consists of Arabica, including this rare Java variety. The Java beans are part of a broader effort to preserve and revive heritage Arabica cultivation in the region.

Growing Conditions and Production Today

Cameroon’s fertile volcanic soils, high altitudes, and balanced rainfall create ideal conditions for producing coffee with a profile that can rival South American origins. The country’s Arabica offerings often present a full-bodied, soft mouthfeel with low acidity and hints of red berries, chocolate, and earthiness.

The Java variety is grown by the Caplami Cooperative in the Southwest Region’s Paffo-Ussam area, at elevations of 5,000 feet (approximately 1,500 metres). The cooperative, established in 1958, adopted coffee-growing techniques from experts in Kenya, Tanzania, and Rwanda. Today, the Java beans are processed using a semi-washed (semi-washed process) method, though some lots may also undergo fully washed then 100% sun-dried processing. Annual production is extremely limited, with only around two containers exported globally each year.

The coffee flowers between April and May, and is harvested from September through December. Altitudes range between 1,200–1,800 metres, contributing to the slow maturation and complex cup qualities.

Physical Traits and Grading

Cameroon Java long beans are distinctive for their elongated shape. They are typically graded as size 16 mesh and above, with a ‘’ (Special Selection) grade. The most commonly cited commercial size is 18 screen, identifying them as long beans in the global trade. Defect rates are not strictly formulaic but generally average around 30 defects per 300 grams. The beans are sorted to ensure a minimum quality standard suitable for specialty markets, albeit in very limited supply.

The export grading system in Cameroon classifies beans from GG (largest) down to G4, with the Java variety typically falling into the higher-grade categories due to its careful selection and processing.

Cup Profile and Kenneth Davids’ Notes

Though a formal cupping report from Kenneth Davids is referenced in the original article, the detailed sensory notes are not provided in the source text. However, based on the processing method (semi-washed and/or washed then sun-dried) and the variety’s genetic background, one can expect a cup that leans towards traditional Typica-like profiles: likely balanced, with moderate acidity, a full body, and tasting notes that may include chocolate, nuts, and subtle fruit.

The cup quality reflects the careful growing environment and the heritage of the Java variety, contributing to its reputation as a unique offering in the specialty coffee landscape.

Processing and Historical Context

The Java variety in Cameroon has survived decades of upheaval. From the late 1980s to the mid-1990s, the country’s coffee industry collapsed due to plummeting global prices and the withdrawal of government agricultural support. Farmers abandoned coffee farming en masse during this period.

It wasn’t until the late 1990s and early 2000s that some farmers began reviving coffee cultivation—not as a cash crop driven by subsidies, but as a sustainable livelihood using entirely natural and low-input farming methods. The Caplami Cooperative has been central to this revival, focusing on quality over quantity and preserving unique varieties like Java.

Frequently Asked Questions

What is the Java variety of coffee?

The Java variety is an old-lineage Arabica coffee, historically linked to Typica coffee from Java Island and possibly the same genetic source as Blue Mountain. It was introduced to Cameroon in 1905 by German colonists and cultivated at a trial station in Dschang. It is known for its potential to produce balanced, full-bodied cups and is distinct from more common varieties like Bourbon or Typica found today.

Where is Cameroon Java coffee grown?

Cameroon Java coffee, specifically the long-bean variety, is grown by the Caplami Cooperative in the Southwest Region of Cameroon, in the Paffo-Ussam area. The beans are cultivated at elevations between 1,200–1,800 metres in the Western Highlands, an area known for volcanic soils and favourable climatic conditions.

How are Cameroon Java beans processed?

Cameroon Java beans are processed using a semi-washed (semi-washed process) method. Some lots may also be washed and then 100% sun-dried. This combination of processing helps develop a clean yet complex cup profile while preserving the unique characteristics of the Java variety.

What does a long coffee bean indicate?

Long coffee beans, such as the Cameroon Java variety, typically indicate a specific genetic lineage (like Typica or Java) and are often associated with higher screen sizes (e.g., 18 screen or 16 mesh and above). These beans are graded and sorted for quality, with elongated shape being one of their distinguishing physical traits.

Why is the Cameroon Java variety rare?

The Java variety is rare due to limited planting, historical declines in Cameroon’s coffee sector, and the dominance of Robusta production. Only around two containers of Java beans are exported annually, and the variety is primarily preserved by small cooperatives like Caplami that focus on heritage cultivation.

What is the typical defect rate for Cameroon Java beans?

The defect rate for Cameroon Java beans is not strictly fixed, but the article mentions an approximate average of 30 defects per 300 grams. This places them within a reasonable range for specialty-grade coffees, especially given the limited production and manual sorting involved.
