Nowadays, it seems like canephora is one of the hottest topics of conversation in the specialty-coffee industry. We recently had coverage of Mikolaj Pociecha’s book “Robusta/Canephora” and got to try Cherry Love Coffee’s new Canephora Experience Box Set. In addition, we spoke to Lucas Venturim of Venturim Farms about revolutionizing canephora production in Brazil. Today, we’ll take a step back and go back to the roots of canephora—and why the coffee species is experiencing a renaissance in the coffee world today.

While “robusta” is the commercial term used across the industry, Coffea canephora (or “canephora”) is the botanical name of the coffee species—one that encompasses genetic and geographical diversity. Over the past two decades, agro-scientific research and specialty techniques, such as controlled fermentation and selective harvesting, have elevated the quality of robusta and begun to reshape its perception in the global market.

A key milestone came in 2010, when the Coffee Quality Institute (CQI) introduced the Fine Robusta Standards, adapting arabica protocols to recognize the species’ unique characteristics and reinforce its value in the specialty sector.

Importantly, the use of the word “fine,” rather than “specialty,” reflects the effort to appreciate canephora on its own sensory terms, without forcing comparisons to arabica. This protocol helped create a structured method to evaluate robustas that are free from defects and possess desirable sensory attributes, allowing the industry to move beyond a commodity mindset.

Today, actors across science, consumption, and global trends are organically converging around canephora, not as a rival to arabica, but as a foundational species that kept the coffee world turning for over a century. Canephora has sustained economies, communities, and agricultural resilience—often without recognition. While it has historically received only a fraction of the research and quality-focused attention given to arabica, we are now witnessing a renewed global effort to appreciate, evaluate, and understand canephora.

Genetics and Biology

Arabica is the child of canephora and Coffea eugenioides—a natural hybrid. Unlike arabica, which self-fertilizes, canephora is open-pollinated—its offspring are genetically diverse unless cloned, making variety naming more complex. Because of this, canephora is best evaluated by genetic group, not variety; its cross-pollinating nature makes plant behavior highly context-dependent.

The two main genetic groups of canephora are the Congolese Group—often called robusta—and the Kouillou-Guinean Group. Both originated in Central Africa, particularly in what is now the Republic of Congo and surrounding areas. The Kouillou group is associated with the western parts of the region, while the Congolese group is more common in the central and eastern zones.

The Congolese group includes vigorous, disease-resistant plants that thrive in lowland tropics. It is found in the species’ endemic origins such as the Democratic Republic of Congo, Uganda, and Gabon, and has been widely adopted in producing countries like Vietnam, India, Ivory Coast, and the Brazilian Amazon.

The Kouillou or Guinean group adapted especially well in Brazil’s Espírito Santo state and helped shape the country’s modern canephora sector. Commercially known as conilon in Brazil, the name derives from “Kouillou,” the region in the present-day Republic of Congo where the original plants were first collected.

Angola is home to Kouillou-type plants and played a key role in the development of Brazil’s conilon. Gabon and Cameroon hold both wild and cultivated populations that align mostly with the Congolese group, with some genetic overlap due to the transitional nature of the region.

Canephora as a Survival Crop

Canephora, commercially marketed as “robusta coffee,” is the second most traded coffee species globally, accounting for roughly 40% of global volume according to ICO data. Its top five producing countries today are Vietnam, Brazil, Indonesia, India, and Uganda. Compared to arabica, canephora is more resistant to diseases and thrives in higher temperatures in lower-altitude farming (typically 200–800 meters), in warm and humid subtropical or tropical climates.

The first commercial cultivation of canephora was documented in the late 19th century, in what is now the Democratic Republic of Congo and Uganda—both native origins of the species. From there (1900–1930), farming expanded into Asian and African regions such as Indonesia, Angola, India, and Timor, driven by the species’ higher resistance to coffee rust. The rust epidemic in arabica crops was a major turning point that laid the foundation for robusta’s global spread.

Amid wars and post-colonial transitions, robusta often proved the only coffee that could grow and deliver under pressure—becoming central to soluble coffee and high-volume blends.

Robusta and Trade

It was only in the 1990s that canephora fully entered global trade through the convergence of post-Cold War liberalization, global consumption growth, and the scaling up of production in Brazil and post-war Vietnam. Its inclusion in futures contracts at the LIFFE coffee futures market—now known as Intercontinental Exchange (ICE) Futures Europe—marked this new era. Today, it makes up over 40% of total coffee traded volume, with annual output nearly tripling in the past three decades.

This period may have solidified robusta’s position in the supply chain—but not yet in the conversation on quality. And while arabica’s link to “quality” gained momentum through specialty-coffee, robusta was rarely offered the same attention. There was no need for studying and improving quality, just yield numbers—until very recently, says Dr. Enrique Alves of Embrapa, part of the team of researchers releasing the Canephora Flavor Wheel this year. “Old school robustas were dry and woody. Now we’re seeing fruitiness, boozy notes, even brightness. It’s a whole new universe,” he shared with Barista Magazine.

For Enrique, the goal is not to compare species, but to build a more diverse and inclusive future. “The future of coffee isn’t arabica versus robusta,” he says. “It’s about embracing diversity, and canephora has a lot to offer.”
