How Coffee Is Harvested and Processed: From Fruit to Green Bean

Ever wondered how your cup of coffee began—as a bright red fruit hanging twenty feet up a tree? Specialty coffee starts not in a roastery, but on mountainous farms where each cherry must be picked at peak ripeness. But getting from tree to roasted bean isn’t simple: it involves careful harvesting and complex processing that shapes your coffee’s final flavour.

Coffee cherries are picked by hand when fully ripe (deep red), then processed immediately—either via natural (dry) or washed (wet) methods. Natural takes 12–15 days in sun, while washed takes just 20–24 hours with water. Each method dramatically affects taste, cost, and bean quality.

What Is Coffee and Where Does It Grow?

Coffee comes from the fruit of Coffea plants, which belong to the Rubiaceae (madder) family. These evergreen shrubs grow naturally along a narrow subtropical band around the world, typically at altitudes near 6,000 feet (about 1,800 metres). Wild coffee trees can reach 20 feet tall, but are usually pruned to 8–10 feet to make harvesting easier. The plants take 3–5 years to bear fruit, first flowering with small white blossoms similar to jasmine. After pollination, green berries form, then turn yellow, red, and finally deep red when ripe. Inside each cherry are two seeds—we call these coffee beans.

How Are Coffee Cherries Harvested?

Coffee cherries do not all ripen at once. To ensure only ripe fruit is picked, nearly all specialty coffee is harvested manually, by hand, one cherry at a time. This labour-intensive method allows pickers to select only the deep red, fully mature cherries, which is essential for high-quality coffee. Machines are sometimes used for low-grade commodity coffee, but they cannot match the precision of hand-picking.

How Is Coffee Processed After Harvest?

Once picked, coffee cherries must be processed quickly to prevent spoilage. There are two main methods: natural (dry) and washed (wet). Each affects the final flavour, body, and cleanliness of the green bean.

Natural (Dry) Process

In the natural process, whole coffee cherries are spread out to dry in the sun for 12–15 days. The fruit dries around the seeds, and after drying, the outer skin, pulp, and parchment are removed to reveal the green bean. This method is low-cost and requires minimal equipment, but it often results in uneven drying, risk of fermentation, and earthy or fermented off-flavours if it rains or is poorly managed. The beans produced tend to have fuller body but can be less clean in the cup.

Washed (Wet) Process

The washed process is more complex and costly, but yields cleaner, brighter flavours. Within 20–24 hours of picking, the cherries are pulped to remove the outer skin, then the beans (still coated in mucilage) are soaked in water. Fermentation breaks down the sticky layer, after which the beans are washed clean and dried on patios or raised beds for 10–14 days until they reach around 11–12% moisture. The outer parchment is still present at this stage. These beans are called “parchment coffee.” Before export, the parchment is removed, and the green beans may be polished and sorted by grade. The washed method produces cleaner, more aromatic, and consistent cups with higher acidity and clarity.

What Happens to the Beans Before Export?

After processing, the beans are dried to a safe moisture level. In the natural process, this happens while the fruit is still intact; in the washed process, it occurs after the mucilage is removed and the beans are dried as parchment. Once dried, the beans are stored in their parchment layer (“parchment coffee”) to protect them. Right before export, the parchment is removed in a hulling process, revealing the green bean. The beans are then sorted, graded, and sometimes polished before being packed for shipment.

What Are the Main Coffee Varieties?

There are three primary species of coffee cultivated globally:

• Arabica (Coffea arabica): Originating in Ethiopia, Arabica makes up 70–80% of global production. It is known for its complex flavours, higher acidity, and lower caffeine content. Most specialty coffee is Arabica.
• Robusta (Coffea canephora): Native to the Congo, Robusta accounts for 20–30% of global production. It has a harsher, more bitter taste, higher caffeine, and is mostly used in instant coffee and espresso blends for crema and body.
• Liberica (Coffea liberica): Grown almost exclusively in Liberia, this variety makes up less than 5% of world production. It has a very strong, distinctive flavour with intense bitterness and aroma.

Frequently Asked Questions

Why are coffee cherries picked by hand instead of by machine?

Coffee cherries ripen at different times even on the same tree, so hand-picking ensures that only fully ripe, deep red cherries are collected. This improves quality, especially for specialty coffee. Machines are used mainly for low-grade coffee where uniform ripeness is less critical.

What’s the difference between natural and washed coffee processing?

Natural (dry) processing dries the whole coffee cherry in the sun for 12–15 days, resulting in a fuller body but risk of off-flavours. Washed (wet) processing removes the skin and pulp first, ferments the beans, then dries the naked seeds for 20–24 hours, yielding cleaner, brighter, and more acidic cups with better consistency.

How long does coffee processing take?

Natural processing takes about 12–15 days of sun drying. Washed processing takes roughly 20–24 hours for initial processing, plus 10–14 days of drying the parchment coffee. Total time varies with weather and method.

What is parchment coffee?

Parchment coffee refers to dried coffee beans that are still encased in a thin, paper-like husk called parchment. This protective layer is removed just before export, leaving the green bean ready for roasting.

Which coffee species is best for specialty coffee?

Arabica is the dominant species for specialty coffee, making up 70–80% of global production and offering complex flavours, higher acidity, and lower bitterness. Robusta is mostly used for instant coffee due to its harsher taste and higher caffeine content.
