How Coffee Beans Are Picked, Processed, and Dried

When you sip your morning espresso or pour-over, you’re tasting the result of a long journey that began on a coffee tree — not as a bean, but as a fruit. But how does a bright red coffee cherry become the green bean you roast? The answer lies in careful harvesting, precise processing, and controlled drying. This is how specialty coffee begins.

Coffee cherries turn bright red when ripe and are typically harvested once a year, either by hand-selecting only ripe fruits or stripping entire branches. After picking, the beans are processed using either the natural (dry) or washed (wet) method, then dried to 11% moisture. Each step affects flavor, body, and aroma — especially in specialty coffee.

What Is a Coffee Bean, Really?

The coffee bean is not a bean at all, but a seed found inside a fruit that looks like a cherry. These coffee cherries grow in clusters on branches. The outer skin (exocarp) is thick and bitter, while the sweet, pulpy layer (mesocarp) feels like grapes. Beneath that is a sticky layer called the parenchyma, which protects the beans. The beans themselves are coated in a parchment-like skin (endocarp) and have a thin silvery membrane (silver skin) on the surface. Two green coffee beans are found inside each cherry.

When and How Are Coffee Cherries Harvested?

Coffee is usually harvested once per year, depending on the region. In the Northern Hemisphere, the harvest runs from September to March; in the Southern Hemisphere, it’s April to May. Most coffee is picked by hand. There are two common methods: strip picking, where all cherries are removed at once, and selective picking, where only ripe, red cherries are chosen. Selective picking is more labor-intensive and is generally reserved for high-quality Arabica beans.

What Are the Main Coffee Processing Methods?

After picking, coffee cherries must be processed to remove the fruit and dry the beans. There are two main methods:

Dry Process (Natural Process)

This is the simplest and most economical method. Coffee cherries are spread out in the sun and turned regularly with rakes. They dry for seven to ten days until their moisture content drops to 11%. During this time, the outer skins turn yellow, and the beans inside become loose and rattle. This method is used in many origin profiles, including Ethiopia and Brazil, and often results in sweeter, fruitier cups due to prolonged contact with the fruit.

Wet Process (Washed Process)

In the wet method, the fruit pulp is removed from the beans within 24 hours of harvest using a pulper. The beans are then placed in fermentation tanks for 12 to 48 hours, where natural enzymes break down the sticky mucilage. After fermentation, the beans are either sun-dried or machine-dried. This method tends to produce cleaner, brighter flavors and is widely used for high-quality washed Arabicas.

How Are the Coffee Beans Dried and Sorted?

Once processed, the beans — still wrapped in parchment — are dried. For natural processed coffees, this happens while the fruit is still intact. For washed coffees, it occurs after pulping and fermentation. Drying continues until the beans reach 11% moisture. After drying, all remaining layers — parchment and silver skin — are removed in a process called hulling. The beans are then sorted by size and density, either manually or using air blowers to separate lighter, defective beans from heavier, higher-quality ones.

What Happens After Drying?

The final product is green coffee — unroasted beans ready for export. Green coffee is typically packed in jute or burlap sacks, or large plastic containers, and shipped globally. Each year, over 7 million tons of green coffee are shipped worldwide. These beans maintain their quality until roasted, when their true flavors emerge.

Frequently Asked Questions

What does a coffee bean look like inside the cherry?

A coffee bean is actually a seed found inside a coffee cherry. Each cherry usually holds two green beans covered in a thin, silvery skin (silver skin) and a thicker parchment layer (parchment). The beans are surrounded by a sticky mucilage layer, sweet pulp, and a tough outer skin.

How do you know when coffee cherries are ready to pick?

Coffee cherries are ready for harvest when they turn a bright red color. At this stage, the beans inside have reached maturity. Some varieties, like yellow bourbon, may turn yellow instead of red when ripe.

What is the difference between dry and wet coffee processing?

Dry processing (natural) involves drying the whole coffee cherry in the sun, with the fruit intact. Wet processing (washed) removes the fruit pulp within 24 hours, then ferments and washes the beans before drying. Dry processing enhances sweetness and body, while wet processing highlights clarity and acidity.

How long does coffee drying take?

Drying coffee cherries takes about 7 to 10 days in the sun for the dry method, or several days for washed beans after fermentation. Natural processed coffees like Ethiopia’s Yirgacheffe may dry for up to 27–30 days under specific conditions.

What happens after coffee beans are dried?

After drying, beans are hulled to remove all outer layers, leaving just the green coffee bean. They are sorted by size and density, then packed in jute or burlap sacks for global shipment. These green beans are unroasted and ready for roasting before brewing.
