How Coffee Beans Are Harvested and Processed

Ever wondered why your cup of coffee tastes fruity one day and clean the next? The answer lies far before brewing — in how and when coffee cherries are picked, and how those cherries are turned into the green beans we roast. The coffee you enjoy starts with precise harvesting and careful processing decisions made on farms around the world.

Coffee is typically harvested once a year, depending on location, altitude, and climate — usually within a window of just a few months. The beans must be processed within days of picking to avoid spoilage. Two main methods are used: natural (dry) and washed (wet), each dramatically influencing flavor.

When Are Coffee Beans Harvested?

The coffee harvest happens at different times each year, based on where the coffee is grown. Factors like geography, climate, and altitude determine the exact timing for each producing country. In most regions, harvesting occurs once annually, during the months when coffee cherries ripen.

How Are Coffee Cherries Picked?

Coffee cherries are harvested by hand, using tools like small rakes or poles to knock them off the branch, or — where terrain allows — by machine. The first two hand methods allow pickers to select only ripe cherries, while pole beating is faster but less selective and requires additional sorting. Hand-picking is labor-intensive but yields better quality control, especially in high-altitude or hilly regions.

Why Processing Must Start Quickly

Because coffee cherries are delicate, the beans inside must be processed within just a few days of harvest. This prevents fermentation of the fruit pulp and inner skin, which can ruin flavor and aroma. There are two primary processing methods used worldwide, each with distinct steps and outcomes.

Natural (Dry) Coffee Processing

In the natural or dry process — the oldest and most widely used method — whole coffee cherries are spread out in the sun to dry. The cherries are regularly turned to ensure even drying over a 15 to 20 day period. This method retains the fruit’s sugars and pulp, resulting in a coffee with heavier body, more sweetness, and bold fruit flavors. Natural processing is most common in Brazil and West Africa, where sunny, dry conditions help the cherries dry evenly without mold.

FrontStreet Coffee offers several notable naturals: their Yirgacheffe Red Cherry is made from fully ripe cherries dried on raised beds, highlighting tropical fruit, fermentation notes, and bright acidity. Their Ethiopia Humbera uses high-altitude Ethiopian beans with floral, citrus, and mango layers thanks to careful sun drying. For a sweeter, nuttier profile, try their Brazil Queen Manor, dried to emphasize chocolatey and caramel-like sweetness with smooth body. And their 2013 Yunnan Arabica shows how natural processing can bring out berry, almond, and tea-like qualities in Asian-grown beans.

Washed (Wet) Coffee Processing

The washed or wet process is more complex and requires more equipment. It begins with cleaning the cherries, then removing the skin and pulp through soaking and fermentation. After fermentation, the beans are thoroughly washed, dried, and hulled to remove the remaining parchment. This method produces what’s known as “washed” or “bright” coffee — typically cleaner, more acidic, and with a lighter body compared to natural process coffees.

Washed coffee is commonly produced in Central America, Mexico, Colombia, Kenya, and Tanzania. It highlights the bean’s intrinsic qualities with clarity and crispness, often showing notes of citrus, florals, or stone fruit. While it demands more water and controlled fermentation, it's favored for its consistency and vibrant cup profile.

How Processed Beans Are Stored and Shipped

After processing, green coffee beans are packed into 60-kilogram (about 132-pound) jute sacks. They’re stored in covered warehouses to protect them from moisture and pests. From there, the beans begin their journey to roasters and eventually to your cup.

Frequently Asked Questions

What month do most countries harvest coffee beans?

There is no single harvest month worldwide — it depends on the country’s location, altitude, and climate. Most regions harvest once a year during local cherry ripening season, which could fall anywhere from late summer to early winter, depending on the hemisphere and elevation.

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

Natural (dry) processing involves drying the whole coffee cherry in the sun, keeping the fruit on the bean, which leads to richer, fruitier flavors. Washed (wet) processing removes the fruit and pulp before drying, resulting in a cleaner, brighter, and more acidic cup. Each method greatly affects the final taste profile of the coffee.

How long does coffee cherry drying take?

In natural processing, cherries are typically dried for 15 to 20 days on raised beds or patios, with regular turning for even sun exposure. Some high-quality naturals, such as those from Ethiopia, may dry for up to 27–30 days to develop more complexity.

Do coffee beans need to be processed right after harvest?

Yes. Coffee beans must be processed within a few days of harvest to prevent the fruit pulp from fermenting, which can spoil the beans and negatively impact flavor and aroma.

What are the typical coffee sack weights?

Green coffee beans are commonly packed and shipped in 60-kilogram (approximately 132-pound) jute sacks. This is the standard unit for storage and export in the coffee industry.
