Where Coffee Beans Grow and How They’re Made

Ever wondered where your coffee beans really come from — beyond the package? Before that rich brown coffee lands in your grinder, it travels thousands of miles, passes through many hands, and undergoes a complex journey from plant to cup. Understanding how coffee grows and is processed helps explain why your morning brew tastes the way it does.

Coffee beans grow in over 60 countries near the equator, mostly between 300–2,500 metres above sea level. The top producers are Brazil (30%), Central America and Colombia (together 60%), then Africa and Arabia (30%), with the rest from Asia and Pacific islands. Your coffee’s flavour starts with where — and how — it’s grown.

What Is a Coffee Bean, Really?

The coffee bean is actually the seed inside a bright red or purple fruit called a coffee cherry. Each coffee tree produces 3–5 kilograms of cherries yearly, which yield about 20% that weight in green coffee beans after processing. The cherry has layers: outer skin, pulp, sticky mucilage, parchment (called silver skin), and finally the bean. Turning that fruit into the green beans you roast involves multiple steps — and many people.

Where Coffee Grows Best

Ideal coffee-growing conditions include steady temperatures around 20°C, annual rainfall between 1,500–2,000 mm, and high altitudes — especially above 1,500 metres, where beans develop more complexity. Most coffee farms sit between 300–400 metres, but specialty-grade beans often come from higher elevations. Frost-free zones are a must. Coffee is typically planted at elevation to slow growth, allowing more flavour to develop in the beans.

Three Main Coffee Species

The coffee plant belongs to the Rubiaceae family. There are three main cultivated species:

• Arabica (Coffea arabica): Makes up around 66% of global production. It prefers cooler, high-altitude climates, has an oval, flat bean shape, and produces nuanced, aromatic, and higher-quality flavours. It’s the foundation of most specialty coffee.
• Robusta (Coffea canephora): Bold, bitter, and less aromatic. It thrives at low altitudes, resists disease better, and is commonly used in instant and espresso blends for body and crema. Around 30–34% of global coffee is Robusta.
• Liberica (Coffea liberica): Rare, with poor yield and flavour. Mostly exported to Europe, not common in Japan or specialty markets.

Flat Beans vs Peaberry Beans

Most coffee cherries hold two seeds that flatten against each other, resulting in the typical flat-sided bean (known as a “flat bean”). But about 5% of cherries produce just one round seed — called a peaberry or caracol. These beans are often separated and sold separately, though their flavour isn’t necessarily stronger or different. Most coffee you drink will be made from flat beans.

How Coffee Beans Are Processed

After harvest, coffee cherries must be turned into green beans through one of two main methods:

Dry (Natural) Process

In this traditional method, whole cherries are dried in the sun with all layers intact. This is how most Brazilian, Ethiopian, and Yemeni beans are processed. The method is simple but weather-dependent, and unripe or defective beans are harder to remove. Beans gain more body but can be inconsistent without careful sorting.

Washed (Wet) Process

Here, harvested cherries are first soaked to remove floating poor-quality fruit. Then a pulper removes the skin and pulp. The beans, still coated in sticky mucilage, soak in water tanks for 12–24 hours to ferment. After fermentation, the beans are rinsed, dried (either in the sun or with machines), and hulled to remove the parchment layer. This method yields cleaner, brighter flavours, with fewer defects. About 70% of beans from Colombia, Mexico, and Guatemala use washed processing. When done well, it highlights the bean’s intrinsic qualities — but poor fermentation can create off-flavours.

From Farm to Cup: Exporting Green Coffee

Once processed, green coffee beans are sorted, bagged in jute or grainpro sacks, and shipped worldwide in containers. Every step — from cherry to container — involves decisions that shape your coffee’s final taste.
