Coffee Harvest: How Coffee Is Picked and Why It Matters

Coffee does not begin as a brown bean. It begins as a fruit.

Before coffee can be roasted, ground and brewed, it has to be harvested from a coffee plant in the form of a small fruit known as a coffee cherry. And the moment at which that cherry is picked can have a surprisingly large influence on the quality of the coffee inside it.

Coffee harvesting can be done by hand or by machine, all at once or selectively over several passes. The method depends on the country, terrain, size of the plantation, labour available and, importantly, the type of coffee the producer wants to make.

At Herradura Coffee Farm, on Spain’s Costa Tropical, we grow Arabica coffee alongside mangoes, avocados, cherimoyas and other tropical and subtropical crops. Working with coffee plants directly gives us a very different perspective on harvesting: coffee cherries do not simply become ripe on a convenient date. You have to watch the plants.

What Is the Coffee Harvest?

The coffee harvest is the period when ripe coffee cherries are collected from the coffee plants.

Each coffee cherry normally contains two seeds. These are what we eventually call coffee beans.

Before harvesting, however, they are surrounded by several layers of fruit. As the cherry develops, it changes colour and the seeds inside mature. Depending on the variety, ripe cherries are commonly red or yellow.

The important point is that coffee is a fruit crop.

Just as you would not expect an unripe mango and a perfectly ripe mango to taste the same, the stage at which a coffee cherry is harvested matters.

When Is Coffee Harvested?

There is no single worldwide coffee harvest season.

Coffee is grown across a huge geographical area, and harvest dates vary according to latitude, altitude, rainfall, temperature and local climate.

In many traditional coffee-growing regions, flowering is closely connected to rainfall patterns. After flowering and fruit development, producers can anticipate a relatively defined harvest season.

But local conditions can change the picture considerably.

Coffee grown close to the equator may behave differently from coffee grown near the climatic limits of coffee cultivation. Altitude can also delay development, while temperature influences the speed at which cherries mature.

This is one reason statements such as “coffee is harvested from October to February” should always be treated carefully. That may describe a particular country or region, but not coffee cultivation everywhere.

How Do You Know When Coffee Cherries Are Ripe?

Colour is the most obvious indication.

Coffee cherries usually begin green and gradually change colour as they mature. Many Arabica varieties develop a deep red colour when ripe, although some varieties produce yellow or orange fruit.

But colour is only part of the story.

A ripe cherry also changes in texture and composition as sugars develop in the fruit. Experienced growers learn to recognise these changes by looking at and handling the cherries.

One complication quickly becomes obvious when you stand in front of a coffee plant:

not every cherry ripens at the same time.

You can have green, partially ripe and fully ripe cherries on the same branch.

This is one of the reasons selective harvesting exists.

How Is Coffee Picked?

There are three main approaches to harvesting coffee: selective hand picking, strip picking and mechanical harvesting.

Each has advantages and disadvantages.

Selective Hand Picking

Selective picking means harvesting only cherries that have reached the desired level of ripeness.

Workers move through the plantation and pick ripe cherries individually, leaving immature fruit on the plant.

They may then return to the same plants later as the remaining cherries mature.

This is labour-intensive, but it gives the producer much greater control over what enters the harvest.

It is particularly useful for higher-quality coffees because green or overripe cherries can introduce undesirable flavours and inconsistency.

Strip Picking

Strip picking is much faster.

Instead of selecting individual ripe cherries, most or all of the cherries are removed from a branch at once.

The harvested material therefore contains cherries at different stages of maturity and may require sorting afterwards.

For some production systems, the increased efficiency makes this worthwhile.

Mechanical Harvesting

On large plantations with suitable terrain, coffee can also be harvested mechanically.

Harvesting machines move through rows of coffee plants and use vibrating mechanisms to remove cherries.

This dramatically reduces the amount of manual labour required and makes it possible to harvest very large areas efficiently.

However, mechanical harvesting is not suitable everywhere.

Steep mountain plantations, irregular planting layouts and small farms can make machinery impractical or impossible to use.

This explains why hand harvesting remains common in many coffee-producing regions.

Hand-Picked vs Machine-Harvested Coffee

It is tempting to say that hand-picked coffee is automatically better than mechanically harvested coffee.

The reality is more complicated.

The important factor is not simply whether a human or machine removed the cherry. What matters is the quality and uniformity of the fruit entering processing.

Selective hand picking makes it easier to harvest only ripe cherries.

Mechanical systems prioritise efficiency and scale, although modern farms can combine mechanical harvesting with sophisticated sorting systems afterwards.

A well-managed mechanical harvest can therefore produce good coffee, while badly managed hand harvesting does not guarantee quality.

Nevertheless, when production is small and quality is the priority, selective hand picking offers an obvious advantage: you can choose the fruit directly on the plant.

Why Does Ripeness Matter?

The coffee seed develops inside a living fruit.

During ripening, important chemical changes take place within the cherry. Sugars develop, acidity changes and the composition of the fruit surrounding the seed evolves.

Harvesting too early means collecting immature cherries.

Waiting too long can create different problems, including overripe or damaged fruit.

For quality-focused production, the goal is therefore not simply to harvest coffee quickly. It is to collect cherries within the desired window of maturity.

This sounds simple until you have hundreds or thousands of cherries ripening at slightly different speeds.

Agriculture rarely follows the calendar as precisely as we would like.

Coffee Harvesting in Spain

Spain is far outside the regions normally associated with commercial coffee cultivation.

Most of the world’s coffee is produced within the tropical belt between the Tropics of Cancer and Capricorn. Southern Spain lies considerably farther north.

Yet the subtropical microclimate of the Costa Tropical of Granada makes it possible to grow crops that would be unusual elsewhere in continental Europe.

Mangoes, avocados, cherimoyas and other tropical and subtropical species have been cultivated here for decades.

Coffee can grow here too.

At Herradura Coffee Farm, we grow Arabica coffee among these crops, allowing us to observe how coffee behaves under Mediterranean conditions.

Our scale also makes selective harvesting possible. Instead of treating the plantation as a crop that must be harvested on one particular day, ripe cherries can be picked by hand as they mature.

That matters because the plants do not read the calendar.

Even within a small area, individual plants — and individual branches — can develop differently.

Why Coffee Doesn’t Ripen All at Once

Visitors are often surprised when they see coffee plants carrying cherries of several colours simultaneously.

From an agricultural perspective, this is perfectly normal.

Flowering does not necessarily occur at exactly the same moment across every plant. Differences in exposure, temperature, water availability and the individual plant can influence development.

That variation continues as the cherries mature.

The result is that harvesting can require several passes through the same plants.

The first pass removes cherries that are ready.

Others remain on the tree.

Days or weeks later, another group may have reached maturity.

For a small coffee plantation, this is manageable. For a plantation covering hundreds or thousands of hectares, the economics are completely different.

Scale changes how coffee has to be harvested.

What Happens After Coffee Is Picked?

Harvesting is only the beginning.

Once the cherries have been collected, the coffee seeds must be separated from the fruit and dried before they can eventually be roasted.

Different processing methods handle the fruit differently.

In the washed process, much of the fruit is removed before the coffee is fermented, washed and dried.

In the natural process, the whole coffee cherry is dried with the seeds inside.

There are also intermediate methods, including honey processing, where part of the fruit material remains around the seed during drying.

Processing has a major influence on the character of the final coffee.

But none of these methods can completely compensate for poor-quality fruit.

Good processing starts with good cherries.

How Long Does a Coffee Harvest Last?

Again, there is no universal answer.

On some plantations, harvesting is concentrated into a relatively short period.

Elsewhere, cherries may mature over several months.

Selective harvesting naturally extends the process because workers repeatedly return to the plants.

Climate also plays an important role.

Rainfall, temperature, altitude and flowering patterns all influence how concentrated or extended the harvest becomes.

This is why understanding a coffee’s origin involves more than knowing the country written on the bag.

Two farms in the same country can experience very different growing and harvesting conditions.

Does Coffee Have One Harvest Per Year?

Many coffee-growing regions have one principal harvest each year.

However, coffee plants respond to their local environment rather than to a universal agricultural schedule.

Some regions can experience secondary harvests or more continuous flowering and fruit development.

Rainfall patterns are particularly important in many tropical coffee regions because rain can stimulate flowering after a dry period.

Where climate is less predictable, flowering and fruit development can also become less uniform.

This creates another reminder that coffee agriculture varies enormously from one region to another.

How Harvesting Affects Coffee Quality

A cup of coffee is the result of a long chain of decisions.

Variety matters.

Soil matters.

Climate matters.

Water matters.

Processing matters.

Roasting matters.

Brewing matters.

But before most of those later stages can influence the cup, somebody has to decide which cherries leave the coffee plant.

Harvesting is therefore one of the first major quality filters in coffee production.

If a harvest contains a high proportion of immature, damaged or overripe cherries, later processing becomes more difficult.

Careful harvesting creates better raw material to work with.

It does not guarantee exceptional coffee, but it gives the rest of the process a much better starting point.

From Coffee Cherry to Cup

When people first visit a coffee plantation, one of the biggest surprises is often simply seeing what coffee looks like before processing.

There are no brown coffee beans hanging from the tree.

There are green leaves, branches and colourful cherries.

Inside those cherries are the seeds that will eventually be dried, processed, roasted and transformed into something recognisable as coffee.

Between the ripe cherry and the cup lies an extraordinary amount of work.

Harvesting is one of the moments where agriculture and coffee quality meet directly.

And once you have picked coffee cherries yourself, it becomes difficult to look at a bag of coffee simply as a finished product.

You begin to see the fruit behind the bean.
