The Four Types of Coffee Trees Grown Around the World

Coffee lovers rarely think about where their morning cup actually begins—but it all starts with a tree. Whether you’re brewing a simple filter or pulling a shot of espresso, the coffee cherry that made it grew on one of just four main species of coffee trees. If you've ever wondered how Colombia became famous for its high-quality beans or what really makes Arabica different from Robusta, you're not alone.

There are four coffee tree species in the world: Arabica, Robusta, Liberica, and Excelsa. Of these, Arabica is the most widely grown and prized, especially in Colombia, where it dominates production thanks to generations of careful breeding and ideal growing conditions.

The Origins and Global Journey of Coffee

Coffee originated in Kaffa, Ethiopia, but it found its way to Colombia in 1808, brought by a priest traveling from the French Antilles via Venezuela. Today, Colombia ranks as the world’s fourth-largest coffee producer, following Brazil, Vietnam, and Indonesia. Its coffee industry thrives due to a combination of ideal geography, unique farming practices, and a well-established national system.

The Four Main Coffee Tree Species

Globally, there are four recognized species of coffee trees: Arabica, Robusta, Liberica, and Excelsa. Each has multiple varieties or cultivars. In Colombia, Arabica dominates commercial cultivation, particularly a locally developed hybrid known as the Colombia variety. This cultivar was bred by Colombian agronomists to be highly resistant to pests and diseases while also delivering high yields. Unlike the more bitter and harsh Robusta, Arabica is celebrated for its nuanced flavors and aromatic complexity, making it the preferred species for specialty coffee.

Why Colombian Coffee Stands Out

Colombia’s reputation for quality coffee is no accident. Several key factors contribute to the excellence of its beans:

1. Ideal Natural Conditions

Coffee grows best in tropical regions between the Tropic of Cancer and the Tropic of Capricorn, at elevations of 800 to 1,600 meters. Colombia lies just north of the equator, below 13 degrees latitude, and its famed Coffee Triangle—spanning three provinces—sits at around 1,200 to 1,400 meters above sea level. The rugged Andes Mountains provide well-drained soils, consistent rainfall, and plenty of sunlight without frost risk. This environment allows coffee trees, which range from shrub height to over four meters tall, to flourish much like tea plants in China. The Colombian Coffee Triangle’s altitude and microclimates are often considered superior even to those in Brazil.

2. Unique Processing Methods

Coffee production begins with seeds carefully selected from the middle of the coffee cherry—beans that are plump and glossy. These seeds are planted in special bags and nurtured into seedlings resembling bean sprouts or matchsticks. Over six months, the seedlings develop leaves, and after about eight months, they’re ready for transplanting. A coffee tree takes roughly two years to yield fruit and can produce for around eight years before it’s cut down to regrow. Trees may bear flowers and cherries simultaneously; the white flowers resemble jasmine but lack fragrance. The cherries, about the size of a cherry, are smooth and come in red or yellow. Each cherry typically holds two coffee beans.

Colombian coffee is processed using the washed method: the fruit’s flesh and skin are removed, and the beans ferment before being used as fertilizer. The beans are then soaked to remove mucilage, dried, and have their parchment layer removed before roasting. The longer and hotter the roast, the deeper and richer the flavor; shorter roasts yield a softer taste. Unlike Brazil, where machines harvest all cherries indiscriminately and skip washing, Colombian coffee is handpicked—twice a year, in May and October—selecting only perfectly ripe fruit. This careful harvesting and processing contribute significantly to its superior cup quality.

3. Strong Organizational Structure

Colombia established a national coffee growers' federation early on. Farmers deliver their harvests to the federation, which has offices worldwide to market Colombian coffee. With smart branding and marketing strategies, Colombian coffee gained international renown. About 25% of Colombian coffee exports go to Germany, and a significant amount to the U.S.—including to Starbucks. The federation’s Juan Valdez brand, representing the archetypal Colombian coffee farmer, is the country’s flagship, though many locals prefer more affordable local brands like Sello Rojo or OMA, which also offer great flavor. Some farmers are even considering creating their own private labels, especially those with large estates like the 75-hectare farm mentioned in the original account.

Frequently Asked Questions

What are the four types of coffee trees?

The four coffee tree species are Arabica, Robusta, Liberica, and Excelsa. Arabica is the most common and favored for specialty coffee due to its flavor complexity. Robusta is stronger and more bitter, often used in instant coffee. Liberica and Excelsa are rarer, with unique flavor profiles and less global presence.

Why is Colombian coffee so highly regarded?

Colombian coffee benefits from ideal growing conditions in the Andes Mountains at 1,200–1,400 meters altitude, thorough hand-picking of ripe cherries, and a washed processing method that enhances cleanliness and sweetness. The country also has a strong national coffee federation that ensures quality control and global marketing.

What is the Colombia coffee variety?

The Colombia variety is a hybrid coffee cultivar developed by Colombian agronomists. It is a type of Arabica bred for high yields and strong resistance to pests and diseases, making it one of the most reliable and flavorful coffees grown in the country.

How is coffee processed in Colombia?

In Colombia, coffee is processed using the washed method. The coffee cherries are depulped to remove the fruit, then the beans are fermented, washed, and dried. This process results in a cleaner, brighter cup compared to natural or honey processing methods.

How often are coffee cherries picked in Colombia?

Coffee cherries in Colombia are harvested twice a year, typically in May and October. Only fully ripe cherries are handpicked, ensuring higher quality and flavor in the final coffee.

Are there different species of coffee trees?

Yes, there are four main species: Arabica, Robusta, Liberica, and Excelsa. Each species has distinct growing requirements, flavors, and levels of caffeine. Arabica accounts for the majority of specialty coffee production.
