How Coffee Beans Are Picked and Named by Country

When you take a sip of coffee, you might imagine the rich aroma filling your cup or the deep amber color of the brew—but have you ever wondered how those beans reached your filter? Most coffee lovers know little about the journey of the coffee bean, from a bright red cherry on a tropical tree to the green seed inside your roaster’s offering.

Coffee cherries are picked at peak ripeness—when they turn deep red—for the best flavor. Proper harvesting, growing altitude, and processing methods directly affect the coffee’s final taste and quality.

What Is a Coffee Bean, Really?

What we call a coffee bean is actually the seed found inside the fruit of the coffee plant, commonly referred to as the coffee cherry. These cherries start out green, turn yellow-green, and finally ripen to a bright red. Each cherry usually holds two oval seeds that are flat on one side where they touch—these are what we call "flat beans" or . Occasionally, a cherry produces just one round seed—this is a "peaberry" or —and while it looks different, it doesn’t taste significantly different.

Where Do Coffee Beans Come From?

Coffee is grown in around 60 countries, mostly at elevations between 300 and 400 meters. However, some of the highest-quality beans come from farms at higher altitudes, particularly between 1,500 and 2,500 meters above sea level. The very best coffee is often cultivated above 1,500 meters on sloped land, where cooler temperatures and thinner air slow growth and develop more complex flavors.

Ideal coffee-growing conditions include:

• Average annual rainfall: 1,500–2,000 mm
• Average temperature: around 20°C (68°F)
• No frost

How Are Coffee Beans Harvested and Processed?

Coffee harvesting requires careful timing to pick only fully ripe cherries. Once harvested, beans are processed using one of two main methods:

Washed (Wet) Process

In the washed method, also known as , coffee cherries are pulped to remove the outer skin, then the sticky mucilage is washed away using water and friction in tanks before the beans are dried. This produces a more consistent and cleaner-tasting coffee. The end result is what we call a , or washed coffee bean.

Natural (Dry) Process

The non-washed or natural process involves drying the whole coffee cherry in the sun, then using a hulling machine to remove the dried husk and pulp. This method can yield more varied cup profiles but often results in less consistent quality compared to washed coffee.

Flat vs Peaberry Beans

Most coffee cherries contain two seeds that are flat on one side (flat beans). Rarely, a cherry produces a single round seed (peaberry). Both can produce excellent coffee, though peaberries are sometimes separated and sold separately due to their unique shape.

The Main Coffee Species and Varieties

There are three main cultivated coffee species:

• Arabica : The most widely grown and prized species, known for its complex flavors and acidity. It includes countless cultivars such as Typica, Bourbon, Geisha, and many more.
• Robusta : Hardier and more bitter, with higher caffeine content. Often used in espresso blends for crema and body.
• Liberica : Much rarer, with a distinctive woody, smoky flavor. It makes up a tiny fraction of global production.

Each species includes multiple varieties that are tracked and traded separately. Even within a single country, differences in climate, soil, and altitude create distinct regional flavor profiles—so it’s impossible to generalize a country’s coffee style in just one sentence.

Coffee Farming Altitude and Plant Management

Coffee plants are originally tropical evergreens that can grow over eight meters tall in the wild. On commercial farms, they’re pruned to around two meters to make harvesting easier and improve bean quality. The best specialty coffee is grown at higher altitudes, where cooler temperatures slow maturation, allowing sugars and acids to develop more fully in the bean.

Coffee Bean Specifications: Washed vs Natural

Coffee beans are categorized not just by species, but also by processing method and bean shape:

Washed vs Non-Washed

• Washed : Seeds are removed using water and friction; produces uniform, clean-tasting beans.
• Non-Washed : Dried in the sun, then hulled; can be inconsistent in quality.

Flat Bean vs Peaberry

• Flat Bean : The standard, two-flat-sided seed from most cherries.
• Peaberry : A rare, round single seed from a cherry that produced only one bean. Taste is similar but sometimes more concentrated.

Frequently Asked Questions

What is the best altitude for growing coffee beans?

The best coffee is typically grown at altitudes between 1,500 and 2,500 meters, with particularly high-quality beans coming from farms above 1,500 meters on slopes. These conditions result in slower cherry development and more complex flavors.

What are the main types of coffee beans?

The three main coffee species are Arabica, Robusta, and Liberica. Arabica is known for its complexity and acidity, Robusta for its strength and bitterness, and Liberica for its rarity and smoky flavor.

What is the difference between washed and natural coffee processing?

Washed coffee removes the cherry’s flesh and mucilage using water before drying, resulting in a cleaner, more consistent flavor. Natural coffee dries the whole cherry in the sun before hulling, often producing fruitier but less predictable profiles.

What are flat beans and peaberries?

Flat beans are the typical oval seeds with a flat side from most coffee cherries. Peaberries are rare, round single seeds that develop when only one seed forms in the cherry. They are often separated and sold individually.

How are coffee cherries turned into green beans?

After harvesting, coffee cherries are either washed to remove the fruit and mucilage (washed process), or dried whole and then hulled (natural process), leaving behind the green coffee bean inside the parchment layer.

Does coffee bean shape affect flavor?

Flat beans and peaberries generally taste similar, but some roasters believe peaberries can have a more concentrated flavor due to their single-seed development. However, the difference is subtle.
