Coffee is one of the world's most beloved beverages, with over 2 billion cups consumed daily. However, the industry is facing a serious threat: climate change. Rising temperatures, unpredictable rainfall, and increasing pests are making it harder to grow traditional coffee species like arabica and robusta. This has led to skyrocketing prices and concerns about the future of coffee production.

But amidst this crisis, a little-known coffee species—excelsa—is emerging as a potential solution. Could this rare bean be the key to coffee’s survival?

What Is Excelsa Coffee?

Excelsa coffee (Coffea excelsa), a species within the liberica coffee family, is native to South Sudan, Uganda, and parts of Central Africa. Unlike arabica and robusta, excelsa trees grow much taller—sometimes reaching 49 feet (15 meters)—and are known for their deep root systems, which help them survive extreme drought conditions.

Flavor Profile: A Unique Coffee Experience

Excelsa has a rich, complex flavor that sets it apart from traditional coffee varieties. It is often described as having:

  • A sweet, fruity taste similar to arabica

  • Notes of chocolate, dark fruit, and hazelnut

  • Less bitterness and more body than robusta

Despite its potential, excelsa currently makes up less than 1% of the global coffee market.

How Climate Change Is Threatening Coffee

Coffee plants are highly sensitive to environmental changes. Some of the biggest climate-related threats include:

  • Rising Temperatures: Arabica, which thrives in cooler mountain regions, struggles with higher temperatures, reducing yields and flavor quality.

  • Unpredictable Rainfall: Coffee requires consistent rainfall patterns, but climate change is causing longer droughts and unseasonal floods.

  • Pests and Diseases: Warmer climates are increasing the spread of coffee diseases like coffee leaf rust and pests like the coffee borer beetle.

These challenges are already impacting major coffee-producing countries like Brazil, Colombia, and Ethiopia, leading to unstable prices and supply shortages.

Why Excelsa Could Be the Future of Coffee

Excelsa coffee stands out as a climate-resilient alternative because of its:

1. Drought and Heat Resistance

Unlike arabica and robusta, excelsa thrives in hotter, drier climates. Its deep roots and thick leaves allow it to retain moisture and survive in regions that would be too harsh for other coffee species.

2. Natural Pest and Disease Resistance

Excelsa is naturally resistant to many common coffee pests and diseases, reducing the need for pesticides and making it a more sustainable crop.

3. Potential for Expansion

Countries like South Sudan, Uganda, and Vietnam are beginning to explore excelsa farming. Some specialty coffee producers in Europe and Asia are also showing interest in bringing this rare bean to a wider market.

Challenges in Scaling Excelsa Coffee

While excelsa has incredible potential, it faces several hurdles:

1. Lack of Awareness and Market Demand

Because excelsa is relatively unknown, there is little global demand. Specialty coffee roasters are beginning to experiment with it, but widespread adoption will take time.

2. Difficult Harvesting Process

Excelsa trees grow significantly taller than arabica and robusta, making harvesting more labor-intensive unless they are pruned. Farmers need training and resources to make cultivation more efficient.

3. Limited Infrastructure in Key Growing Regions

Countries like South Sudan, where excelsa grows naturally, lack the infrastructure to process and export coffee efficiently. High transportation costs and political instability also make it difficult for farmers to scale production.

What Needs to Happen for Excelsa to Succeed?

For excelsa coffee to become a mainstream alternative, several key steps must be taken:

  • Investment in Research & Development: More studies are needed to improve excelsa farming techniques and optimize yields.

  • Support for Small Farmers: Governments and international organizations should fund training programs and infrastructure to help farmers grow and sell excelsa coffee.

  • Consumer Awareness & Specialty Coffee Demand: Coffee lovers and roasters need to learn about excelsa’s unique flavor profile to create a demand for this climate-resistant coffee.

  • Stronger Supply Chains & Export Networks: Investing in better transport, processing facilities, and global trade partnerships will help bring excelsa coffee to international markets.

Conclusion

While excelsa coffee is still relatively unknown, it could be the future of coffee in a warming world. Its resilience to climate change, unique flavor, and potential for sustainable farming make it an exciting alternative to traditional coffee species.

However, for excelsa to thrive, farmers, researchers, and coffee companies must work together to scale production, improve processing, and educate consumers. If successful, this little-known coffee species could play a crucial role in ensuring that coffee lovers around the world continue to enjoy their daily cup—even as climate change reshapes the industry.

FAQs

What makes excelsa coffee different from arabica and robusta?

Excelsa has a unique flavor profile with fruity, chocolatey, and nutty notes, similar to arabica but with a bolder body. It is also more resistant to drought, heat, and pests, making it a potential solution for climate-threatened coffee farms.

Why is climate change a threat to traditional coffee crops?

Arabica and robusta, the two most widely consumed coffee species, struggle with rising temperatures, erratic rainfall, and increased pests and diseases. This leads to lower yields, higher prices, and declining coffee quality.

Where does excelsa coffee grow?

Excelsa is native to South Sudan, Uganda, and parts of Central Africa, and is also cultivated in Vietnam, India, and Indonesia. Its ability to withstand extreme weather makes it suitable for hotter, drier regions.

Can excelsa coffee replace arabica and robusta?

While excelsa has the potential to supplement traditional coffee species, it currently represents less than 1% of the global coffee market. Scaling up production requires investment, better infrastructure, and increased consumer demand.

How can I try excelsa coffee?

Excelsa coffee is still rare but can be found in specialty coffee shops and online retailers. As awareness grows, more coffee roasters may begin offering it.
