How Coffee Cherries Are Harvested and Processed

Coffee doesn’t just magically appear roasted and ground in your café — before that, someone had to pick it by hand. Most of the world’s coffee grows in countries with lower labor costs, and it shows: harvesting coffee cherries is still one of the most labor-intensive parts of coffee production. Especially for high-quality beans, every cherry matters.

To make specialty-grade coffee, pickers harvest only fully ripe red coffee cherries by hand — and often return multiple times to the same tree since cherries ripen unevenly. This selective picking is essential for quality, but it demands significant time and labor.

Why Hand-Picking Matters for Quality Coffee

Not all coffee cherries ripen at the same time. On a single tree, you’ll find green (unripe), red (ripe), and sometimes overripe or black cherries. To produce high-quality coffee, only bright red, fully ripe cherries are picked. That means pickers must carefully select them one by one, and often revisit the same tree several times during the harvest season. Machines can’t do this — they strip all cherries at once, mixing unripe and overripe fruit, which leads to inconsistent flavors.

Two Main Ways to Process Coffee Cherries

Once harvested, coffee cherries must be processed to remove the fruit and dry the seeds (what we call beans). There are two primary methods: washed (or wet) process and natural (or dry) process. Each affects the final flavor differently.

Washed Process

In the washed method, the coffee cherry’s skin and pulp are removed mechanically before fermentation. The beans, still coated with sticky mucilage, are soaked in water tanks for fermentation — usually 12 to 72 hours depending on conditions. This breaks down the mucilage so it can be washed away with water. Then the beans are dried, either in the sun or with machines, until their moisture content drops to around 11%. Finally, a hulling machine removes the parchment layer to reveal the green coffee bean.

This method, used for FrontStreet Coffee’s Yirgacheffe Gedeb Cooperative, Kenya Little Tomato, and Jamaica Blue Mountain No.1, results in brighter acidity, cleaner profiles, and more consistent quality. Fermentation in water alters the bean’s chemistry, reducing some sugars and increasing acidity.

Natural Process

The natural (or dry) method is simpler: whole coffee cherries are spread out to dry in the sun on patios or raised beds for about two weeks. Workers regularly turn and rake the cherries to ensure even drying. Once the fruit is fully dry — typically to 11–12% moisture — the outer skin, pulp, and parchment are removed using a hulling machine.

This process is less common among the featured FrontStreet beans but is widely used in regions like Ethiopia and Brazil. It tends to produce coffee with lower acidity and more diverse, fruity, or fermented flavor notes due to prolonged contact between the bean and fruit sugars.

Washed vs. Natural: Flavor & Consistency

Both washed and natural processing methods can produce excellent coffee — but they highlight different qualities. Washed coffees generally have a cleaner cup, higher perceived acidity, and more uniform quality due to controlled fermentation. Natural-processed coffees often have heavier body, more complex fruitiness, and more variable profiles. The choice impacts not just taste, but also how the coffee is roasted and brewed.

Frequently Asked Questions

Do all coffee cherries ripen at the same time?

No — coffee cherries on a single tree ripen at different rates. Some turn red (ripe) while others remain green or overripe. High-quality coffee requires hand-selecting only the bright red, fully ripe cherries, often needing multiple passes through the same tree over the harvest period.

What is the washed coffee process?

The washed process removes the coffee cherry’s skin and pulp before fermenting the beans in water to break down the mucilage. The beans are then washed, dried to 11% moisture, and hulled to remove the parchment. This produces cleaner, brighter, and more consistent coffee flavors.

What is the natural coffee process?

In the natural process, whole coffee cherries are dried in the sun with the fruit still attached. After drying, the beans are hulled to remove the dried fruit, pulp, and parchment. This method often yields coffee with more body and fruity, fermented notes but less consistency than washed coffee.

Which process gives coffee more acidity?

Washed coffee typically has brighter, more pronounced acidity because the fermentation in water reduces some sugars and enhances organic acids. Natural coffee tends to have lower acidity and more varied, often sweeter or fruitier flavor profiles.

Why can’t coffee be harvested by machine?

Machines strip all coffee cherries off the branch at once, regardless of ripeness. This mixes unripe, ripe, and overripe cherries, leading to inconsistent flavor. Selective hand-picking of only ripe cherries is essential for high-quality specialty coffee.

Recommended FrontStreet Beans for Washed Processing

FrontStreet’s Yirgacheffe Gedeb Cooperative highlights the washed method with jasmine floral notes and bright citrus acidity. The Kenya Little Tomato uses double washed processing to deliver sweet-tart flavors like tomato, plum, and blackcurrant. The classic Jamaica Blue Mountain No.1 is cleaned and bright with hazelnut, cream, and chocolate notes. All three show what careful washing can do.
