Where Coffee Beans Come From: The Production Process

You’ve probably heard coffee comes from beans—but have you ever wondered where those beans actually grow? Despite Starbucks making coffee mainstream, most people don’t know coffee beans are the seeds inside bright red or yellow fruits that grow on trees. Understanding how coffee beans are produced helps explain why your cup tastes the way it does, and what choices go into every sip.

In short: coffee beans come from the seeds of coffee cherries, which grow on tropical trees. There are over 500 coffee species and 6,000 varieties, but just two—Arabica (70% of global production) and Robusta (20–30%)—dominate the commercial market. These two species produce the vast majority of specialty and everyday coffees due to their distinct flavor profiles and adaptability to different growing conditions.

The Coffee Tree: More Than Just a Bean Source

Coffee doesn’t grow on bushes or vines—it grows on trees. The coffee tree, depending on the species, can reach between 3 and 10 metres tall in the wild, though cultivated trees are often pruned shorter to make harvesting easier. The actual coffee beans are the seeds found inside the fruit of the coffee tree, commonly referred to as the coffee cherry. Each cherry typically contains two beans, though sometimes just one (called a peaberry).

Major Coffee Species: Arabica vs. Robusta and Beyond

Globally, there are four main coffee species, but only two are widely grown for commercial coffee production:

• Arabica (Coffea arabica): Accounts for around 70% of the world’s coffee. Known for its smoother, more nuanced flavors, Arabica beans are grown at higher altitudes and are more sensitive to growing conditions. Famous coffees like Jamaica Blue Mountain, Yirgacheffe, and many single origins are Arabica. Most specialty coffee is Arabica-based.
• Robusta (Coffea canephora): Makes up about 20–30% of global production. Originating in the Congo, Robusta is hardier, grows at lower altitudes, and has a stronger, more bitter flavor with higher caffeine content. It’s often used in espresso blends for added crema and body.
• Liberica (Coffea liberica) & Excelsa (Coffea excelsa or considered a subtype of Liberica): These make up less than 1% of production. Liberica has a unique, woody, smoky flavor and is grown in Southeast Asia; Excelsa offers tart, fruity notes and is mainly found in parts of Southeast Asia.

From Cherry to Coffee Bean: How Coffee Is Harvested and Processed

Coffee beans start as the seeds inside coffee cherries, which are harvested by hand or machine when ripe. The two main processing methods are:

• Washed (Wet) Process: The coffee cherry’s skin and pulp are removed before the beans are fermented and dried. This method highlights cleaner, brighter flavors.
• Natural (Dry) Process: The whole cherry is dried in the sun before the beans are removed. This often results in sweeter, fruitier, and more full-bodied flavors.

After drying, the beans (now called green coffee beans) are milled to remove the parchment layer, sorted by size and quality, and exported. They are then roasted—transforming green beans into the aromatic brown beans used for brewing.

Why Arabica and Robusta Dominate the Market

Though there are thousands of coffee varieties, Arabica and Robusta dominate because of their balance of flavor, yield, disease resistance, and adaptability to farming. Arabica thrives at higher elevations with cooler temperatures, producing a more delicate cup, while Robusta is more disease-resistant and grows well at lower altitudes, offering a stronger, more bitter profile. Other species like Liberica and Excelsa are rare due to lower yields, niche flavors, or difficulty in cultivation.

Coffee Bean Varieties and Flavor Profiles

Even within the Arabica species, flavor varies dramatically based on factors like soil, altitude, climate, and processing. For example:

• High-altitude Arabicas often have bright acidity and floral or fruity notes.
• Lower-altitude beans may taste more earthy or chocolatey.

This diversity is why single-origin coffees taste so different from one another—and why blends are crafted to balance flavors.

Frequently Asked Questions

Are coffee beans actually beans?

No, coffee “beans” are not beans botanically—they are the seeds of the coffee cherry fruit, which grows on coffee trees. They only became known as “beans” because of their bean-like shape.

How many coffee beans are in a cup of coffee?

A standard single cup of coffee (about 12–16g of ground coffee) typically uses around 60–80 coffee beans, depending on bean size, roast level, and brewing method.

What’s the difference between coffee beans and coffee powder?

Coffee beans are the whole, unground seeds harvested from coffee cherries. Coffee powder, or coffee grounds, is what you get after grinding the beans. The grind size affects brewing method and extraction.

Which coffee beans are best for Americano or espresso?

For espresso—including Americano—darker roasted Robusta or Arabica-Robusta blends are common for boldness and crema. However, many specialty drinkers prefer medium or dark-roasted single-origin Arabica for a more complex shot.

Can I grow coffee trees at home?

Yes, in tropical or subtropical climates, or in controlled indoor environments with adequate light and humidity, you can grow small coffee trees. They can fruit, but homegrown harvests are usually very small.
