82+ Coffee Varieties in Specialty Bean Collections

If you’ve ever wondered how many actual coffee plant varieties exist beyond the usual names like Arabica or Robusta—or why certain beans taste radically different—this guide lays out the hard numbers and real diversity in global coffee germplasm collections. Whether you’re a roaster, a green buyer, or just deeply curious, you’ll find out exactly which cultivated and wild types are preserved, studied, and even grown for production today.

There are 247 known coffee species, varieties, and forms that can be collected and preserved. Of those, 82 have already been introduced into a dedicated coffee variety garden, with plans to reach 100–150. This includes major cultivated species like Arabica, Robusta, and Liberica, as well as one wild ancestor.

What Is a Coffee Variety Garden?

A coffee variety garden serves as a living library for coffee genetic resources. Covering 3 acres, such gardens focus on collecting, conserving, and observing the plant and growth traits of various coffee types. These observations then support classification, identification, and breeding of superior cultivars. The goal isn’t just preservation—it’s also research into which plants perform best under different conditions.

The Four Main Coffee Species Collected

The coffee variety garden focuses on four major cultivated species, each representing a different segment of global coffee production:

• Arabica (Coffea arabica): The most widely grown and economically important coffee species, known for high cup quality.
• Robusta (Coffea canephora, syn. C. robusta): Hardier, higher-yielding, and more bitter—common in commercial blends and instant coffee.
• Liberica (Coffea liberica): Rare and unusual in flavor and plant structure, with limited global production.
• Wild Coffee (Coffea sylvestris): The uncultivated, original species from Ethiopia’s forests, a progenitor of modern cultivated coffee.

Arabica Varieties: The Catimor Group and Beyond

Within the Arabica species, the garden has collected numerous varieties and forms. The most numerous and significant group is the Catimor series, a group of hybrid cultivars developed by Portugal’s International Rust Research Centre. Catimors are widely planted due to their resistance to coffee leaf rust and high productivity. Notable examples include:

• Catimor P4: The highest-yielding Arabica variety in the world.
• 7963: Another prominent Catimor line.

Beyond Catimors, the collection includes:

• Mexico series: 14 distinct varieties.
• Malaysia series: 2 varieties.
• Other Arabica types: 46 additional cultivars and forms.

One legendary Arabica variety, Jamaica Blue Mountain, originates from the Catimor family tree and is renowned worldwide for its exceptional cup quality—though it is not explicitly listed among the 82 introduced varieties.

Robusta and Liberica: The Other Commercial Species

The garden has also preserved:

• Robusta (Coffea robusta / C. canephora): 8 collected varieties. Known for its strong, bitter flavor and high caffeine content, Robusta is essential for instant coffee and espresso blends needing crema and body.
• Liberica (Coffea liberica): 1 collected variety. This species produces large cherries and has a unique, woody flavor profile. It is rarely cultivated commercially today.

The Wild Ancestor: Coffea sylvestris

Also part of the collection is Coffea sylvestris, the only wild species currently preserved. This is the original, unselected coffee plant from the tropical forests of Ethiopia—the birthplace of coffee cultivation. It has never been domesticated and represents the genetic root from which all cultivated coffee varieties descend.

Why This Collection Matters

Having 82 coffee types gathered in one place allows researchers and breeders to compare plant traits, disease resistance, yield potential, and cup quality. It supports the development of new varieties that combine productivity with flavor, climate resilience, and pest resistance. For the specialty coffee industry, understanding this genetic base is key to innovation and sustainability.

Frequently Asked Questions

How many coffee species and varieties are there in total?

There are 247 known coffee species, varieties, and forms that can potentially be collected and preserved. This includes cultivated types and wild relatives.

How many coffee varieties have been introduced into the coffee variety garden?

82 coffee varieties (including species, subspecies, and cultivated forms) have already been introduced into the coffee variety garden. The goal is to eventually collect between 100 and 150 varieties.

Which coffee species are included in the collection?

The collection includes four main cultivated species: Arabica (Coffea arabica), Robusta (Coffea robusta), Liberica (Coffea liberica), and one wild species, Coffea sylvestris. Arabica is the most extensively represented.

What is the most commonly grown coffee variety in the world?

The Catimor series, especially varieties like Catimor P4 and 7963, are among the most widely planted due to their rust resistance and high yields. Catimor P4 is noted as the highest-yielding Arabica variety globally.

Is wild coffee still part of the cultivated coffee gene pool?

Yes, the wild ancestor Coffea sylvestris is included in the collection. It originates from Ethiopia’s forests and is the progenitor of all cultivated coffee, though it is not used commercially today.

Why are variety collections important for coffee production?

Variety gardens help researchers study plant traits like disease resistance, yield, climate tolerance, and flavor potential. This supports the development of improved coffee varieties suited to changing growing conditions and market demands.
