Two Main Types of Coffee Species Names Explained

Ever wonder why two bags of ‘100% Arabica’ coffee can taste wildly different—even when both claim premium quality? The answer isn’t just about roast level or origin. It often comes down to the specific coffee tree variety, a factor as influential as terroir or processing.

There are two main categories of coffee species names: traditional, naturally evolved ‘old’ varieties and scientifically developed ‘new’ hybrids or genetically modified types. Each affects flavor, yield, disease resistance, and farming sustainability in unique ways.

What Are the Two Main Categories of Coffee Species?

In specialty coffee, professionals generally group coffee trees into three broad types—natural varieties, cultivated hybrids, and genetically modified strains—but for clarity, they’re often referred to simply as ‘tree species’ or ‘varieties.’ These categories are defined by how the plants were developed and how they perform in the field and cup.

1. Old Varieties (Naturally Selected or Traditional Types)

‘Old’ coffee varieties aren’t ancient, but they evolved naturally or were selected over time without human crossbreeding. Many gained fame due to unique flavor profiles or historical significance. These include:

• Ethiopian and Yemen Mocha (Moka): Among the oldest known and most flavor-prized.
• Typica: A foundational variety with wide global spread and balanced flavor.
• Bourbon: Known for high sweetness and complexity; widely grown in Latin America.
• Blue Mountain: Grown in Jamaica, prized for mild cup profile.
• Sumatra (var.): Common in Indonesia, often associated with earthy profiles.
• Maragogype (Elephant Bean): A natural mutation from Typica, producing very large beans but with low yield. First appeared around 1870 in Brazil.

More recent natural mutations include:

• Mundo Novo: A cross that emerged around 1920, valued for balance and adaptability.
• Caturra: Developed in 1935, favored in Central America for early harvest and high productivity—but simpler flavor than Typica.
• Catuai: Another 20th-century mutation, offering more complex cup expression than Caturra.

These older types are often celebrated by specialty coffee fans and traditionalists for their heritage and nuanced flavors.

2. New Varieties (Hybrids & Cultivated Crosses)

New varieties are typically the result of deliberate human crossbreeding, often involving other species like Robusta to boost traits such as disease resistance or climate tolerance. While many deliver practical benefits for farmers, they sometimes sacrifice cup quality.

Notable examples include:

• SL-28 & SL-34: Famous Kenyan varieties known for exceptional cup quality, developed in East Africa.
• Various disease-resistant types in Colombia, Brazil, India, and Kenya: Often include Robusta genetics to improve survival rates.

Controversially, some new hybrids offer high yields but muted flavor. For instance:

• Catimor: A hybrid with Robusta lineage, widely criticized for bland cup profiles—but it resists disease and boosts production. Some exceptions (like Kent in India and Variedad Colombia in Colombia) retain complex flavors nearly on par with traditional types.

Governments and farmers often support these varieties for economic and ecological reasons, even at the cost of some sensory qualities.

3. Genetically Engineered Varieties (GMO Coffee)

The most debated category includes lab-developed coffee trees, often modified for specific traits unrelated to traditional breeding. Examples under research include:

• Caffeine-free coffee: Developed in Hawaii by reversing the gene responsible for caffeine production; flavor impact is under study.
• Synchronized ripening varieties: Designed to allow all cherries to mature at once, simplifying harvest logistics.

Researchers like John Stiles claim that certain genetic modifications (like removing caffeine) need not affect cup quality—but environmental concerns persist, and none of these GMO types are yet widely approved or commercialized.

Frequently Asked Questions

What is the difference between old and new coffee varieties?

Old varieties are naturally selected or spontaneously mutated plants, often valued for their unique and complex cup profiles, such as Typica, Bourbon, and Mocha. New varieties are intentionally hybridized or genetically modified, frequently to improve yield, disease resistance, or climate resilience—though they may sacrifice flavor complexity.

What are some examples of traditional coffee tree varieties?

Common old or traditional coffee varieties include Typica, Bourbon, Mocha (from Yemen/Ethiopia), Blue Mountain, Maragogype, Mundo Novo, Caturra, and Catuai. These are often appreciated for their flavor characteristics and historical importance.

Are hybrid coffee varieties less flavorful?

Some hybrid varieties, especially those with disease resistance or high yield goals like Catimor, are often considered less complex in the cup. However, there are exceptions—certain hybrids like Variedad Colombia and Kent maintain richer flavor profiles similar to traditional types.

What is Catimor and why is it controversial?

Catimor is a hybrid coffee variety with Robusta parentage, valued for its disease resistance and high productivity. However, it’s widely criticized for producing dull or simple cup flavors, making it controversial among specialty coffee professionals.

Are there genetically modified coffee trees?

Yes, scientists have developed genetically engineered coffee varieties, such as caffeine-free trees and types designed for synchronized fruit ripening. These are still in experimental stages and not yet widely adopted due to environmental and flavor concerns.

Which coffee varieties are best for flavor?

Many coffee enthusiasts favor older, naturally selected varieties like Typica, Bourbon, and SL-28 for their complex and desirable cup profiles. However, flavor also depends heavily on growing conditions, processing, and roast methods.
