How Coffee Grows: From Tree to Cherry Fruit

Coffee lovers often sip their favorite brew without ever seeing where it began. Ever wondered how the coffee cherry — the fruit that holds your daily brew — grows? Understanding how coffee plants flower, fruit, and ripen helps explain why coffee quality starts in the orchard.

A mature coffee tree typically reaches 5–10 metres tall but is pruned to under 2 metres for easier picking. Each coffee cherry holds two seeds — your coffee beans — and goes through a distinct growth cycle from flower to ripe red fruit over roughly 9 months.

What Is a Coffee Tree?

Coffee trees are evergreen shrubs or small trees that produce white, jasmine-like flowers and green fruits that ripen to a bright red. These red fruits resemble cherries — hence the nickname 'coffee cherry.' Inside each cherry are usually two coffee beans, though a rare single round bean called a peaberry can also form.

Left unpruned, coffee trees can grow quite tall, but farmers routinely prune them to around 2 metres. This height makes hand-harvesting easier and encourages better yields from lower, more manageable branches.

The Coffee Flowering Stage

Coffee trees begin flowering when they are around 4–5 years old, typically in February or March. The flowers are small, white, and strongly fragrant, with five petals that curve backward. They closely resemble jasmine or gardenias in scent and appearance.

The flowers emerge in tight clusters along the branches and bloom for just 3–5 days. Their brief flowering window makes witnessing a full coffee blossom display a rare treat. Pollination happens naturally, often aided by wind and insects, and shortly after, the coffee cherries begin to form.

From Flower to Coffee Cherry

After the flowers fade, green coffee cherries start to develop. These immature fruits are hard, oval-shaped, and a deep green colour. Over the next 6–7 months, they gradually mature, turning from green to yellow and finally to a vibrant red when fully ripe.

Each mature cherry usually contains two flat-sided coffee beans facing each other, encased in a sweet, sticky, yellowish pulp. Surrounding the beans is a thin membrane called the silver skin, and both beans sit inside a hard, protective layer known as the parchment (or endocarp). This parchment shields the beans from the fruity mucilage during growth.

About 5–10% of coffee cherries develop a single round bean instead of two flat ones. These are called peaberries (or caracolillos) and are often separated during processing due to their rarity. Many coffee experts believe peaberries have a more concentrated flavour, though this remains subjective.

What Makes a Coffee Cherry Mature?

The coffee cherry’s colour change from green to red signals ripeness. This transformation takes approximately 6–7 months after flowering. During this time, the fruit develops its sugary pulp and protects the two coffee beans inside.

A typical coffee cherry holds two beans, but a natural mutation may cause it to produce just one rounded bean — the peaberry. These are smaller, rounder, and usually hand-selected due to their scarcity. They are often sold separately and can command higher prices.

The outer red skin is sweet and pulpy. Beneath it lies a layer of mucilage, then the parchment, and finally the silver skin encasing each bean. All these layers must be carefully removed during processing to avoid damaging the green coffee beans inside.

Frequently Asked Questions

How tall does a coffee tree grow?

A mature coffee tree can grow to 5–10 metres naturally, but farmers typically prune them to under 2 metres to make harvesting easier and encourage better fruit production from lower branches.

When does a coffee tree flower?

Coffee trees generally begin flowering at 4–5 years old, with blooms appearing between February and March. The flowers last only 3–5 days and have a strong, sweet fragrance similar to jasmine.

How long does it take for a coffee cherry to ripen?

From flowering to fully ripe cherry, the process takes around 6–7 months. The fruit changes from green to yellow and finally bright red when ready for harvest.

What’s inside a coffee cherry?

Each mature coffee cherry normally contains two coffee beans lying flat against each other. They’re surrounded by sweet pulp, mucilage, a parchment layer, and a thin silver skin. Occasionally, a cherry produces a single round bean called a peaberry.

What is a peaberry coffee bean?

A peaberry is a rare, naturally occurring single round coffee bean inside a cherry, instead of the usual two flat beans. They make up about 5–10% of all coffee cherries and are often separated and sold as a distinct grade due to their perceived richer flavour.

Why are coffee cherries called cherries?

Coffee cherries are nicknamed 'cherries' because their bright red colour and oval shape closely resemble the fruit when ripe. This term is widely used in farming and processing but refers only to the fruit, not the bean inside.
