How Coffee Grows: From Flower to Cherry Fruit

Ever wondered how your morning cup starts—as a flower on a tree? Coffee begins life not as a bean, but as part of a fruit grown on a tree that most people never see. If you’ve ever asked where coffee really comes from or how those ‘cherries’ turn into the beans you roast, this guide breaks down the full journey from flower to your brew.

Coffee trees typically grow 5–10 metres tall in the wild, but are pruned to under 2 metres for easier harvesting. Their white jasmine-like flowers bloom for just 3–5 days, then develop into green fruits that ripen to bright red over 6–7 months—these are the famous ‘coffee cherries.’ Each cherry usually holds two coffee beans, though a rare single round bean called a peaberry can also form.

What Is a Coffee Tree and What Does It Look Like?

A coffee tree is an evergreen shrub or small tree that produces white, fragrant flowers and green fruits that ripen to red. The tree can reach heights of 5 to 10 metres naturally, but is commonly pruned to under 2 metres in commercial plantations to simplify coffee cherry picking. The dark green, oval fruits gradually change colour from deep green to vivid red when ripe, resembling cherries—hence the nickname.

The Coffee Flowering Stage: How Coffee Trees Bloom

Coffee trees begin flowering at around 4 to 5 years old, typically between February and March. The coffee flowers are small, white, and have five petals that curl backward. They emit a strong, sweet fragrance similar to jasmine. The flowers grow in tight clusters along the branches, creating a brief but striking visual display. However, each flower only blooms for 3 to 5 days, making the sight of a coffee blossom ‘cherry blossom’ moment rare and fleeting.

From Flower to Coffee Cherry: Fruit Development Timeline

After the flowers fade, green coffee fruits begin to form. These fruits are initially hard and deep green. Over the next 6 to 7 months, they mature, gradually changing colour until they reach a vibrant red. This red, fleshy exterior is what gives the fruit its cherry-like appearance, leading to the common term ‘coffee cherry.’ Beneath the outer skin is a layer of sweet, sticky mucilage, followed by the hard, protective parchment layer that encases the actual coffee seeds—or beans.

What’s Inside a Coffee Cherry? Anatomy of the Coffee Bean

Each ripe coffee cherry usually contains two coffee beans that sit flat against each other. Each bean is coated with a very thin, silvery membrane known as the silver skin, and both the bean and its silver skin are protected inside a tough, beige-coloured shell called the parchment or endocarp. In rare cases, a cherry will develop only one round bean instead of two. This is called a peaberry (or caracol), which is smaller, rounder, and lacks the usual flat side. Peaberries occur in very small quantities and are often hand-selected, making them more expensive. Many coffee drinkers believe peaberries have a richer, more concentrated flavour due to their rounded shape.

Why Do Some Coffee Cherries Have Just One Bean?

Occasionally, a coffee cherry develops a single round coffee bean instead of the usual pair. This single bean is known as a peaberry, also called a caracol or single bean. Unlike regular flat beans, peaberries are almost perfectly round because they form when one of the two seeds in the cherry fails to develop, allowing the remaining seed to grow without a flat side. Because peaberries are much less common and require careful sorting, they are often sold separately and are considered by some to have a more intense, focused flavour profile. Their scarcity and unique shape contribute to their higher market price.

Frequently Asked Questions

How tall do coffee trees grow naturally?

Coffee trees can grow up to 5 to 10 metres tall in their natural state, but are usually pruned to stay under 2 metres in plantation settings to make harvesting easier.

When do coffee trees flower?

Coffee trees typically flower between February and March, starting at around 4 to 5 years of age. The flowers bloom in clusters and are white with a jasmine-like fragrance, but each flower only lasts for 3 to 5 days.

What colour are coffee cherries when they’re ripe?

Coffee cherries start off green and take about 6 to 7 months to ripen. When fully ripe, they turn a bright red colour, which is why they are commonly called ‘coffee cherries.’

How many coffee beans are in each cherry?

Most coffee cherries contain two beans that sit flat against each other. However, about 5% of cherries contain just one round bean, known as a peaberry, which develops when only one seed forms inside the cherry.

What is a peaberry coffee bean?

A peaberry is a rare, round coffee bean that forms when only one seed develops in a coffee cherry, instead of the usual two. These beans are usually smaller, rounder, and are often separated and sold separately due to their perceived richer flavour and scarcity.

How long do coffee flowers last?

Coffee flowers have an extremely short blooming period of just 3 to 5 days. They are highly fragrant, with a scent similar to jasmine, and bloom in tight clusters on the branches.
