How Coffee Grows: From Tree to Harvest

Ever wondered where your morning coffee actually comes from? The journey begins on a tree—specifically, a tropical evergreen that produces the bright red fruit we call coffee cherries. But how does that cherry become the bean you grind? And why does altitude, climate, and processing matter so much? This guide breaks down everything you need to know about how coffee grows, is harvested, processed, and classified by variety.

Coffee comes from the fruit of a Coffea plant, typically grown around 6,000 feet (1,800–2,000 meters) above sea level in a narrow band of subtropical regions. The trees can reach 20 feet tall but are pruned to 8–10 feet for easier harvesting. It takes 3–5 years for a tree to bear fruit, which starts as white jasmine-like flowers before developing into green berries that ripen to deep red.

What Is Coffee and Where Does It Grow?

Coffee is the seed—or bean—inside the fruit of the Coffea plant, a member of the Rubiaceae (madder) family. These plants naturally grow in a thin strip of the world’s subtropics, roughly along the Equator between the Tropics of Cancer and Capricorn. The most common species, Arabica, thrives at higher elevations, generally between 500 and 2,000 meters, where cooler temperatures and well-defined wet and dry seasons help develop complex flavors.

How Coffee Is Harvested

Coffee cherries do not all ripen at the same time, even on the same branch. That’s why nearly all high-quality coffee is picked by hand. Pickers select only the bright red, fully ripe cherries. This labor-intensive method ensures that only the best fruit is harvested, though it increases cost and time. In some lower-grade or volume-driven production, machines may strip entire branches, harvesting ripe and unripe cherries together—but this is rare in specialty coffee.

How Coffee Is Processed After Harvest

Once picked, coffee cherries must be processed quickly to prevent spoilage. There are two main methods:

• Natural (Dry) Process: Cherries are spread out in the sun for 12–15 days to dry completely. The outer fruit, pulp, and parchment are later removed. This method is cheaper but can result in uneven flavor and fermentation issues if it rains. The beans produced tend to be less consistent and have more earthy or fermented notes.
• Washed (Wet) Process: The cherries are first soaked to remove the skin and pulp, then the beans (still in their mucilage) are fermented in water for 20–24 hours before being washed and dried. This results in cleaner, brighter flavors with less risk of defects. The beans are then dried, still inside a protective parchment layer, and later hulled before export. This method is more costly and labor-intensive but yields higher-quality beans.

After drying, the beans are stored as “parchment coffee” until they’re milled (parchment removed), polished, graded, and prepared for export.

The Three Main Coffee Species

There are three primary coffee species cultivated globally, each with distinct characteristics:

Arabica is the dominant species, accounting for 70–80% of global production. It originates from Ethiopia and includes most specialty coffee varieties. Robusta, from Central Africa, makes up 20–30% of production and is mostly used in instant coffee due to its strong, harsh flavor and higher caffeine content. Liberica, native to West Africa, is rare, making up under 5% of global output, and is known for an intense, unusual bitterness and aroma.

How Coffee Varieties Differ

Beyond species, coffee flavor and growth traits vary based on cultivar, altitude, and climate. Arabica performs best at higher altitudes with cooler temperatures, producing more nuanced cups. Robusta is hardier, tolerating heat, pests, and lower altitudes, but lacks the delicate flavors of Arabica. Liberica is the most resilient to both heat and cold and grows at low elevations, but its flavor is polarizing due to its strong bitterness.

Key environmental needs per species include:

• Arabica: Prefers 500–2,000m altitude, cooler temperatures, moderate rainfall. Sensitive to extreme weather.
• Robusta: Grows well below 500m, tolerant of heat, heavy rain, and drought.
• Liberica: Adapts to lowland or flat areas under 200m, survives diverse climates.

Coffee and Caffeine

Caffeine is the main compound behind coffee’s bitter taste and stimulating effects. Found not just in coffee but also in tea, chocolate, and cola, caffeine affects the body for about 2–3 hours. In moderation, it boosts alertness and circulation. Arabica beans contain 1.1%–1.7% caffeine, while Robusta has a much higher concentration of 2%–4%. Liberica’s caffeine content is not specified in the source.

Frequently Asked Questions

What is the coffee fruit called?

The fruit of the coffee plant is called a coffee cherry. It starts green, turns yellow, then red, and finally deep red or purple when fully ripe. Inside each cherry are usually two seeds—the coffee beans.

How long does it take for a coffee tree to produce fruit?

A coffee tree typically takes 3 to 5 years after planting to bear its first fruit. Once mature, it can produce viable coffee cherries for many years, often decades with proper care.

What are the main types of coffee beans?

The three main coffee species are Arabica, Robusta, and Liberica. Arabica makes up 70–80% of global production and is known for its balanced flavor. Robusta accounts for 20–30% and is stronger and more bitter. Liberica is rare, under 5%, with a unique, intense taste.

Which coffee processing method is better?

The “better” method depends on the desired outcome. Washed (wet) processing results in cleaner, brighter flavors and is preferred for specialty coffee. Natural (dry) processing is simpler and cheaper but can yield more inconsistent and earthy flavors. Both methods are used widely depending on region and resources.

Why are coffee cherries picked by hand?

Coffee cherries don’t all ripen at once. Hand-picking ensures that only fully ripe cherries are harvested, improving quality. This is essential for specialty coffee, though less common in commercial or mass-market production where machines may be used.

Where is Arabica coffee grown?

Arabica coffee grows best at higher altitudes, typically between 500 and 2,000 meters. Major producers include Brazil, Colombia, Ethiopia, Kenya, Honduras, and many Central and South American countries, as well as parts of East Africa and Asia.
