Liberica coffee is one of the lesser-known species of the Coffea genus, yet it holds remarkable potential for the future of coffee cultivation. Among its most distinctive branches is Liberica coffee var. Dewevrei, a variety known for its unique flavor, resilience, and fascinating sub-varieties found across tropical regions.
🌿 Understanding Liberica Coffee
The Liberica species (Coffea liberica) originated in West and Central Africa and is known for its large cherries, tall trees, and bold flavor profile.
Compared to Arabica or Robusta, Liberica beans are larger, more irregular in shape, and have a distinct almond-like aroma when roasted.
Liberica trees are highly resistant to pests and diseases and thrive in hot, humid climates. These traits make them valuable for sustainable coffee farming in regions affected by climate change.
🧬 What Is var. Dewevrei?
The var. Dewevrei (sometimes referred to as Excelsa) is a major botanical variety within the Liberica species.
It was originally identified in Central Africa and named after the explorer Élie Dewevre.
This variety is often considered an intermediate form between Liberica and Excelsa coffees. Its trees are slightly smaller than traditional Liberica but share many of the same resilient qualities. The beans are typically smaller and denser, producing a coffee with complex, fruity, and woody notes.
In recent years, scientists have suggested that Coffea dewevrei may even deserve classification as a separate species, reflecting its genetic distinctiveness and adaptability.
🌱 Sub-varieties of Liberica var. Dewevrei
Over time, several local and regional sub-varieties of Liberica var. Dewevrei have been identified, each adapted to specific environments in Africa and Asia.
While the classification remains under scientific review, the most commonly recognized sub-varieties include:
1. Coffea arnoldiana
Known for its moderate tree size and tolerance to variable climates. It produces beans with balanced acidity and a mild nutty aftertaste.
2. Coffea aruwimiensis
Originating near the Aruwimi River in the Congo Basin, this sub-variety is well adapted to wet, tropical forests. It often displays sweet, floral tones with low bitterness.
3. Coffea dybowskii
A rare and hardy form, found in drier regions. It has excellent drought resistance and a rich, earthy cup profile with subtle spice undertones.
4. Coffea laurentii
Distinguished by its larger leaves and elongated beans. It thrives in shaded areas and is often cultivated in agroforestry systems.
5. Coffea excelsa (syn. dewevrei)
Sometimes treated as a synonym rather than a sub-variety, Excelsa is known for its deep, complex flavor — a mix of tart fruitiness, floral aromas, and dark, lingering notes. It has become a favorite among specialty roasters for its exotic taste.
🌍 Distribution and Cultivation
Liberica var. Dewevrei and its sub-varieties are grown mainly in Central and West Africa, Southeast Asia, and parts of the Philippines and Malaysia.
The plants prefer warm climates, moderate rainfall, and well-drained soil. Because of their resilience, they can grow at lower altitudes where Arabica struggles.
In regions like Malaysia, Indonesia, and the Philippines, these varieties have become an essential part of local coffee traditions — producing distinctive beverages with a bold, smoky sweetness.
☕ Flavor and Cup Profile
Coffees from the Dewevrei group are recognized for their diverse and intense flavors.
Depending on the sub-variety and processing method, the taste can include:
- Woody and smoky undertones
- Floral and fruity acidity
- Nutty sweetness
- Thick, syrupy body
The balance of boldness and brightness makes these coffees ideal for espresso blends or single-origin roasts that stand out from conventional Arabica.
🔬 The Scientific Importance of var. Dewevrei
Beyond flavor, Liberica var. Dewevrei is valuable for its genetic diversity.
It carries traits that can help future coffee breeding — especially disease resistance, tolerance to heat, and adaptability to low altitudes.
Researchers are studying its genome to develop hybrid varieties that combine the flavor quality of Arabica with the resilience of Liberica.
❤️ Why It Matters
As global temperatures rise and Arabica faces increasing challenges, the Liberica-Dewevrei group could become a key player in ensuring coffee’s long-term survival.
Its wide range of sub-varieties offers both farmers and roasters a palette of possibilities — from unique flavors to climate-smart farming solutions.
Exploring Liberica var. Dewevrei is more than discovering a rare coffee — it’s about preserving the diversity and future of coffee itself.
