How Specialty Coffee Beans Are Harvested

Ever wondered how your single-origin Ethiopia Yirgacheffe or Colombia Huila beans begin their journey? Before roasting and brewing, those beans start as red coffee cherries on a tree. But getting them off the plant isn’t as simple as shaking a branch. The way coffee is picked has a direct impact on the quality of your cup.

Coffee beans are harvested either by stripping all cherries off the tree at once or by carefully picking only the bright red, ripe ones. Selective harvesting yields higher-quality beans but takes far more time and effort. Most specialty coffee, especially washed arabicas, relies on selective picking.

What a Coffee Bean Actually Is

What we call a ‘coffee bean’ is really the seed inside a fruit known as a coffee cherry. That cherry has several layers: an outer skin (exocarp), a sweet, pulpy layer (mesocarp), a thin layer called the parenchyma, a parchment-like husk (endocarp), and usually two beans inside, lying flat against each other and covered in a silvery skin. Only the inner seeds are roasted and brewed.

When Coffee Cherries Ripen

Coffee trees typically take 3 to 4 years to mature and begin fruiting. The cherries grow in clusters along the branches. They turn a vivid red when ripe—this is when they’re ready to be picked. For arabica varieties, this generally happens between June and August, while robusta cherries ripen from September to October. Although countries without distinct dry and wet seasons—like Colombia and Kenya—may have two flowerings a year, leading to two harvests, they still generally have just one main annual harvest cycle.

Two Ways to Harvest Coffee

There are two main methods of harvesting coffee cherries: strip picking and selective picking. Strip picking involves harvesting all cherries from the tree at once, regardless of ripeness. This is faster but results in uneven quality. Selective picking, on the other hand, means going through the trees multiple times—usually every 8 to 10 days—and picking only the fully red, ripe cherries. This method is labor-intensive and costly, but it’s essential for high-quality arabica beans, particularly those destined for washed processing.

How Much Coffee Gets Picked

The amount of coffee harvested depends on various factors including tree height and farm layout. On average, a picker can harvest between 50 and 100 kilograms of coffee cherries per day. However, only about 20% of that weight is actual coffee beans—meaning 10 to 20 kilograms of usable beans per picker daily. Standard coffee sacks weigh between 45 and 60 kilograms, so it takes a worker roughly 3 to 6 days to fill one sack.

Mechanical Harvesting and Its Limits

In places like Brazil, producers have tried using mechanical harvesters to cut labor costs. These machines shake the trees so that ripe cherries fall off and are collected in a hopper. However, mechanical picking only works well in areas with flat terrain and evenly spaced, straight rows of trees. Even then, the harvest requires additional sorting to remove leaves, twigs, and underripe or overripe cherries that fall into the collector.

It’s also worth noting that mechanized harvesting is generally less selective, which can lead to inconsistent bean quality. That’s why it’s mostly used for producing lower-cost, commercial-grade coffees rather than specialty lots.

Frequently Asked Questions

What part of the coffee plant is the bean?

The coffee bean is the seed inside the coffee cherry fruit. Each cherry normally contains two beans surrounded by several protective layers: outer skin, pulp, a thin layer, parchment, and a silvery skin. The actual beans are what get roasted.

When are coffee cherries ready to be picked?

Coffee cherries are ready to be picked when they turn bright red. Arabica cherries typically ripen between June and August, while robusta cherries ripen between September and October. Ripe cherries are firm indicators of optimal harvest time.

What is the difference between strip picking and selective picking?

Strip picking removes all cherries from the tree at once, regardless of ripeness, while selective picking involves harvesting only the red, ripe cherries, typically over multiple passes. Selective picking produces higher-quality beans but is more labor-intensive.

How much coffee can one worker harvest in a day?

On average, a coffee picker can harvest 50 to 100 kilograms of coffee cherries per day, but only 10 to 20 kilograms of that is actual coffee beans. It takes about 3 to 6 days for a worker to fill a standard 45–60 kilogram sack.

Can coffee be harvested by machine?

Yes, mechanical harvesters can be used, especially in flat areas like parts of Brazil. These machines shake trees to drop ripe cherries into a collector, but they require post-harvest sorting and work best with uniformly planted trees. Mechanical picking is less selective than hand picking.

Why is selective picking important for specialty coffee?

Selective picking ensures only fully ripe cherries are harvested, which leads to better flavor and higher quality beans—essential for washed and specialty-grade arabicas. This method supports consistency and complexity in the final cup.
