82 Coffee Varieties in a Specialty Coffee Field Guide

If you’ve ever wondered just how many types of coffee plants actually exist—and which ones end up in your cup—this field guide lays it all out. From the high-yielding hybrids that dominate the trade to rare wild strains untouched by human selection, coffee’s genetic diversity is vast. But only a fraction are grown commercially or studied in depth. Here’s what you need to know about the real coffee varieties behind your daily brew.

In total, 247 coffee species, varieties and cultivars are known to science and preserved for research. Of those, 82 have already been collected in a dedicated 3-acre coffee variety garden, with plans to expand to 100–150. This living library helps researchers classify plants, observe traits, and select improved varieties for farming and sensory quality.

What Is a Coffee Variety—and Why Does It Matter?

Coffee varieties are cultivated forms of the coffee plant, selected or bred for traits like yield, disease resistance, flavor, or climate adaptability. They fall under four main species: Arabica, Robusta, Liberica, and wild (uncultivated) types. Each species and variety brings different cup qualities, growth needs, and market value. For specialty roasters and farmers, variety choice directly affects cup profile, productivity, and sustainability.

The Arabica Group: Where Most Specialty Coffee Comes From

Arabica (Coffea arabica) makes up the majority of specialty coffee production. Within the Arabica category, the variety garden has assembled an extensive selection:

• Catimor Series (10 varieties): A group of high-yield, disease-resistant hybrids developed by Portugal’s International Rust Research Centre. These include widely planted commercial types and the top-producing variety worldwide, Coffea arabica var. Catimor P4. Many Catimors balance productivity with acceptable cup quality for their role in global supply chains.
• Mexico Series (14 varieties): Collected genetic material from Mexico, offering a range of agronomic and sensory profiles under evaluation.
• Malaysia Series (2 varieties): Two distinct types from Malaysia included in the collection.
• Other Arabica (46 varieties): A broad mix of additional Arabica types, encompassing both known cultivars and less-documented types.

Notably, the garden also preserves the world’s most renowned high-quality Arabica: Jamaica Blue Mountain (Coffea arabica cv.), originally from Jamaica and esteemed for its refined cup character. This variety is distinct for its low bitterness, smooth body, and complex acidity—traits that make it a classic among specialty enthusiasts.

Robusta & Beyond: Other Commercial and Wild Species

Beyond Arabica, the collection includes other important coffee species:

• Robusta (Coffea canephora, formerly C. robusta; 8 varieties): Also known as Coffea robusta Linden, this species is valued for its strong caffeine content, disease resistance, and suitability for lower-altitude growing. Eight robusta varieties are preserved in the garden, often used in commercial blends for their bold flavor and crema contribution in espresso.
• Liberica (Coffea liberica; 1 variety): A single representative of the large-fruited Liberica species, historically grown in Southeast Asia and known for its unique woody, smoky flavor profile and very large cherries. Though rarely used in specialty today, it remains part of the genetic spectrum.
• Wild Coffee (Coffea sylvestris; 1 variety): The original, uncultivated ancestor of modern cultivated coffee, collected from the tropical forests of Ethiopia—the birthplace of coffee. This wild type has not been selectively bred and offers a glimpse into coffee’s evolutionary origins. It remains of great interest for genetic studies and breeding resilience.

How Coffee Varieties Are Collected and Studied

The 3-acre coffee variety garden serves as a field research station. Its main functions are collecting, conserving, and classifying coffee genetic resources. Researchers track each variety’s botanical features—like leaf shape, cherry size, and growth habit—and study biological traits such as yield potential, disease susceptibility, and climate response. Based on these observations, varieties are identified by species and variety type, and some are selected for further breeding or promotion based on their suitability for farming or cup quality.

The goal is not only preservation but also improvement. By understanding the differences among 82 cultivated types—and eventually up to 150—the garden supports the development of better-adapted, higher-quality, and more sustainable coffee plants for the future.

Frequently Asked Questions

How many coffee species and varieties are there?

There are 247 known coffee species, varieties and cultivars preserved for research. Of these, 82 have been collected in the featured 3-acre coffee variety garden, with plans to eventually include 100–150 varieties.

What is the most commonly grown coffee variety?

The most widely planted variety is Catimor P4, a high-yielding, disease-resistant hybrid from the Catimor series developed by Portugal’s rust research center. It is favored for its productivity, though it varies in cup quality.

What is the highest quality coffee variety?

The Jamaica Blue Mountain variety (Coffea arabica cv.) is considered one of the highest quality coffees in the world. It is known for its mild flavor, smooth body, and lack of bitterness, originating from Jamaica and now preserved in coffee research collections.

What are Catimor varieties?

Catimor varieties are a group of hybrid coffee plants developed for high yield and coffee leaf rust resistance. There are 10 Catimor varieties in the collection, including the top-producing coffee plant globally, Catimor P4.

What is the difference between Arabica, Robusta, and Liberica?

Arabica (Coffea arabica) is known for high cup quality and is the main species used in specialty coffee. Robusta (Coffea canephora) is hardier, higher in caffeine, and often used in commercial blends. Liberica (Coffea liberica) is rare, with large cherries and a distinctive smoky flavor, grown mostly in Southeast Asia.

Why are coffee variety gardens important?

Variety gardens collect, conserve, and study different coffee types to improve understanding of their agronomic and sensory traits. They support breeding programs for better yields, disease resistance, and cup quality, and help preserve genetic diversity for the future of coffee farming.
