What Is Excelsa Coffee? Taste, Origin, Caffeine, & How It Compares

Quick Answer

Excelsa coffee was first treated as its own species. Then in 2006, experts reclassified it as a Liberica variety. Today, it grows mainly in Southeast Asia. It has a two-sided flavor profile that feels fruity and tart, plus dark and woody. It also has less caffeine than Arabica or Robusta. You do not often see it sold as a pure single origin coffee. Production stays small. The trees also grow very tall and take more work to manage. Still, Excelsa stands out for disease resistance and strong adaptation. That matters more as climate change puts pressure on common coffee regions.

Key Takeaways

• Excelsa contains less caffeine than both Arabica and Robusta varieties
  
• It grows on tall trees (15+ meters) that require extensive maintenance
  
• Originally from Africa, now primarily cultivated in Southeast Asia
  
• Features both high-altitude (fruity) and low-altitude (bold) flavor characteristics
  
• Resists coffee leaf rust and other diseases that threaten mainstream varieties
  
• Lacks established market infrastructure despite unique qualities
  

Picture this: You have tasted many coffees from all over. Ethiopian Yirgacheffe. Colombian Supremo. Kona from Hawaii. And then you hear about a bean that even many baristas have not worked with. That is Excelsa coffee. It blends bright fruit notes with deep and rich undertones. It does not fit neat labels, and that is part of the appeal.

And as climate pressure reshapes coffee’s future, Excelsa matters for more than flavor. Its natural toughness makes it worth watching.

The Curious History of Excelsa Coffee

Excelsa coffee has a story of mixed identity. People first found it in 1903 in Central Africa. Some also called it Coffea dewevrei. For more than a century, many classified it as its own species. Then in 2006, botanists reclassified it as a variety of Liberica coffee. That shift still causes confusion today.

This change did not stay inside science journals. It also affected farming and selling. Many farmers and traders still treat Excelsa as its own category. They do this because the beans look different, and the taste can feel different too.

That naming confusion leads to a simple problem. No official production statistics exist. The International Coffee Organization does not track Excelsa on its own. Its market share is too small to measure. So Excelsa sits in a quiet corner of coffee culture. Growers and fans know it well. The wider market often overlooks it.

How Excelsa Plants Differ From Other Coffee Species

Unlike the bush-like Arabica and Robusta plants that dominate coffee farms worldwide, Excelsa grows as a true tree. These giants can reach heights of 15 meters (nearly 50 feet) with a canopy spanning 6-7 meters across.

The leaves stand out too—large, leathery affairs averaging 26cm long by 13cm wide, much bigger than those on Arabica plants. Even the flowers are distinctive and they bloom multiple times throughout the harvest season despite the fruits taking a full year to mature.

The beans themselves are asymmetrical as they average about 9mm long and 6mm wide. These physical characteristics create identification challenges—Komal Sable, a fifth-generation coffee farmer at South India Coffee Co., notes that Excelsa beans are smaller and rounder than the almond-shaped Liberica beans, yet local farmers often group them together. And they call them both "mara kaapi" or "tree coffee."

Perhaps most interesting for coffee drinkers is Excelsa's caffeine content. Lab tests from Brazil's Instituto Agronômico de Campinas show Excelsa contains just 0.86 to 1.13g of caffeine per 100g of beans—lower than both Arabica (1.2-1.5g) and Robusta (2.2-2.7g). For those seeking a gentler caffeine experience without sacrificing flavor complexity, this naturally lower caffeine content offers an intriguing option.

Excelsa vs Arabica vs Robusta – Quick Comparison

Where Does Excelsa Coffee Grow?

Despite its African origins, today's Excelsa production centers in Southeast Asia and India. Vietnam, the Philippines, and Malaysia host significant Excelsa trees, often growing alongside other coffee varieties.

Excelsa thrives at medium altitudes of 1,000-1,300 meters above sea level—lower than premium Arabica's preferred heights but higher than most Robusta. This intermediate altitude range might prove crucial as climate change pushes growing zones upward.

The trees show impressive resilience against common coffee afflictions—they resist coffee leaf rust, nematodes, and the coffee leaf miner moth. This natural hardiness makes Excelsa potentially valuable as climate patterns shift. However, they remain vulnerable to trichomycosis, a fungal disease that can damage crops.

The Distinctive Taste Profile of Excelsa

Excelsa's flavor represents a curious paradox—it somehow captures characteristics of both high and low-altitude coffees simultaneously. The cup offers bright, fruity, tart notes typical of high-grown Arabicas alongside the bold, woody depth associated with lower-grown Robustas.

When properly processed and roasted, Excelsa produces a complex cup. Medium-light roasts bring out berry-like and fruity notes alongside woody and popcorn-like flavors. Darker roasts develop a fuller body with chocolate and cream notes.
This dual flavor profile explains why Excelsa sometimes appears in blends rather than as a single-origin offering—it adds complexity and body to coffee mixtures without overwhelming them.

South India Coffee Co. has recently pushed boundaries with experimental processing methods. Their double-fermented black honey Excelsa offers "complex, very berry-like" notes that showcase what this bean can achieve with specialty treatment.

Challenges in Growing and Processing Excelsa

Several factors keep Excelsa production minimal despite its interesting flavor potential and disease resistance.

First, the trees' extreme height makes harvesting labor-intensive and expensive. Regular pruning becomes necessary yet difficult at heights exceeding 15 meters. It increases production costs significantly.

Second, the extended ripening period complicates harvest planning. Unlike Arabica or Robusta crops that mature more uniformly, Excelsa fruits ripen gradually over an extended period and it requires multiple picking passes.

Third, and perhaps most limiting, no established market infrastructure exists. Without commodity pricing, standardized grading, or consistent demand channels, commercial-scale production remains economically risky. Most Excelsa ends up consumed locally or blended anonymously into other coffee products.

Finally, proper processing methods remain underdeveloped. As Komal Sable notes, Excelsa's denser mucilage and different soluble solid content require specific roasting approaches—it can't simply use profiles developed for Arabica or Robusta. The bean needs higher temperatures or longer roasting times to reach optimal flavor development.

Excelsa's Future in a Changing Coffee Landscape

Climate change is putting pressure on coffee farms across the globe. Warmer weather shrinks the areas where many coffee plants grow well. It also pushes farming into higher hills. That shift can leave less land for coffee. In this setting, Excelsa may offer a useful path forward.

Excelsa can grow well at lower optimum altitudes than Arabica. That matters when heat makes some higher areas harder to manage. It also has natural disease resistance. This can help when pests and plant diseases move into new areas as the climate changes.

Beyond planting it for beans, Excelsa may help in another way. Growers can use it as rootstock for grafting Arabica varieties. Its faster-growing and disease-resistant roots may support more delicate commercial plants. It is similar to giving a weak plant a stronger base. Farmers already use grafting in other crops to blend good traits.

For specialty coffee enthusiasts, Excelsa still feels like new ground. As Komal Sable observes, "there is a market" for beans that taste different. But scaling it is not simple. Price systems are not well set yet. Skilled knowledge is also not widespread.

How to Try Excelsa Coffee

Finding pure Excelsa coffee requires persistence. A few specialty roasters have begun offering small-batch Excelsa, particularly from the Philippines and India. Look for:

• Indian Excelsa from the Western Ghats region
  
• Philippine Barako blends (which sometimes contain Excelsa)
  
• Specialty roasters advertising experimental or rare coffee varieties

When brewing Excelsa, standard methods work well, but consider adjusting:

• Grind slightly finer than for Arabica
  
• Use water just off the boil (205°F/96°C)
  
• Extend brew time slightly to extract full flavor complexity
  

Try both paper-filtered methods and immersion brewing to experience different aspects of its flavor profile

Conclusion

Excelsa coffee sits at an interesting turning point. People overlooked it for years. Now climate change is pushing farmers to look at new options. Excelsa brings a distinct taste, lower caffeine, and strong natural resistance to some plant diseases. That mix gives both farmers and coffee fans a solid reason to pay attention.

But confusion about how it is classified and its small market presence still hold it back. Even so, some producers now handle Excelsa with the same care they once saved for premium Arabica. They pick better cherries. They process with more control. They roast with more purpose. And the cups show it. The results suggest Excelsa has earned more respect than it gets today.

If you like trying new coffee, Excelsa gives you something uncommon. It tastes different from the usual options. It also sits between flavor styles in a way that can surprise you. As climate pressure grows and specialty coffee keeps expanding, this once ignored variety may finally get a stronger place in the coffee market.

Frequently Asked Questions (FAQs)

Is Excelsa the same as Liberica coffee?

No. Botanists have classified Excelsa as a Liberica variety since 2006. But Excelsa still stands apart in keyways. The beans tend to be smaller and rounder. The flavor often feels fruitier and more layered. And it can thrive in different growing conditions. Many coffee professionals still treat them as separate.

Why is Excelsa coffee so rare?

Excelsa grows tall like a tree. That makes harvesting and care harder. It also raises labor costs. Another issue is demand. Without clear pricing and steady buyers, large scale farms do not rush into it. So, production stays limited even though the plant can produce well.

Does Excelsa coffee have less caffeine?

Yes. Excelsa contains about 0.86-1.13g caffeine per 100g beans. That is lower than Arabica at 1.2-1.5g. It is also much lower than Robusta at 2.2-2.7g.

What does Excelsa coffee taste like?

Excelsa often has two sides. You may notice fruity and tart notes like some high-altitude coffees. You may also taste deeper, and woodier notes tied to lower altitude coffees. With careful roasting, you can get berry notes, woody tones, and a full body.

Where can I buy Excelsa coffee?

Some specialty roasters sell Excelsa in small batches. Many sources come from Southeast Asia. You can also find it through Philippine coffee sellers. Some South Indian specialty exporters carry it too. Boutique roasters that focus on rare varieties may offer it from time to time.

Can Excelsa coffee grow in the United States?

Large scale growing is unlikely because Excelsa needs a specific climate. Still, some growers have tested it. Small trials in Hawaii and Puerto Rico have happened. Results have been limited.
