How Coffee Is Harvested and Processed

Ever wondered how your morning coffee beans go from tree to cup? The journey starts with harvesting ripe cherries—but not all methods are equal. Some are careful and selective, others fast but rough. Then comes processing: how those cherries are turned into green beans shapes everything from flavor to quality. Here’s exactly how it works, step by step.

Coffee cherries are usually harvested once a year, depending on the country’s climate and altitude, and must be processed within days to avoid spoilage. The two main methods are dry (natural) and wet (washed), each taking days to weeks and producing distinct cup profiles.

When Are Coffee Cherries Harvested?

Coffee is harvested at different times of the year, depending on the country’s geography, climate, and elevation. Unlike crops picked all at once, coffee cherries ripen unevenly, so skilled harvesters often pick only the ripe ones. The exact timing changes by region and producer.

How Are Coffee Cherries Picked?

Mature coffee cherries are collected by hand using tools like small rakes or poles—or simply picked selectively. The first two methods rely on low-cost labor and allow for careful selection. Striking branches with poles is faster but less precise, often mixing unripe or overripe cherries, requiring extra sorting later. In flat areas, mechanical harvesters can be used where terrain allows.

Why Processing Must Start Quickly

Coffee is a delicate product. After picking, the beans inside the cherries must be processed within days to prevent fermentation of the fruit pulp and inner mucilage. How the cherries are handled next defines the coffee’s final character—and falls into two main methods.

Dry Processing (Natural Method)

The dry or natural process is mainly used in Brazil and West Africa. In this method, whole coffee cherries are spread out on the ground or raised beds to dry under the sun. The cherries are regularly turned to ensure even exposure to sunlight over a 15 to 20-day period. This produces what’s called “natural” coffee, often with fuller body and fruity notes due to prolonged contact between the bean and the fruit.

Wet Processing (Washed Method)

The wet or washed process is more complex and demands greater care. It’s widely used in Central America, Mexico, Colombia, Kenya, and Tanzania. The steps include: cleaning the cherries, soaking them, removing the outer skin and pulp, fermenting to break down the mucilage, washing, and then drying the beans. After drying, the beans are hulled to remove the parchment layer, cleaned of any remaining debris, and sometimes polished. This method yields “washed” or “bright” coffee, typically known for higher acidity and cleaner flavors.

How Processed Coffee Is Stored

Once dried and processed, the green coffee beans are packed into sacks, usually weighing around 60 kilograms (about 132 pounds). These sacks are then stored in covered facilities to protect them from the elements before beginning their journey to coffee-consuming countries.

Frequently Asked Questions

What month is coffee usually harvested?

Coffee is harvested at different times around the world, depending on the country’s geography, climate, and elevation. There is no single harvest month; it varies by region and producer.

What are the two main ways to process coffee?

The two main coffee processing methods are dry (natural) and wet (washed). Dry processing involves sun-drying whole cherries for 15–20 days, while wet processing removes the fruit before drying the beans through steps like fermentation and washing.

How long does coffee take to dry?

In the dry process, coffee cherries take about 15 to 20 days to dry when spread out and regularly turned under the sun.

Does coffee processing affect flavor?

Yes. Dry processing often results in fuller-bodied, fruitier coffee, while wet processing typically produces brighter, cleaner, and more acidic cups.

What happens after coffee is processed?

After processing, the green beans are packed into 60-kilogram sacks and stored in covered facilities before being shipped to consuming countries.

Is coffee processing done by hand or machine?

Both. Hand-picking is common for selective harvesting, while machines can be used in flat areas where terrain allows. Pole stripping is also a manual but less precise method.
