What Does a Coffee Bean Really Look Like on the Tree?

Ever wonder what a coffee bean really looks like before it’s roasted, ground, and brewed? Most coffee drinkers never see the plant itself—just the end product. But understanding how coffee beans grow helps explain why they taste the way they do. Every coffee bean starts life as part of a fruit on a living, growing plant. Let’s break down what that plant and its fruit really look like, step by step.

The coffee bean you know is actually one of two seeds found inside a bright red, cherry-like fruit that grows on a small tropical tree. Each mature coffee cherry typically holds exactly two seeds—those are the coffee beans. From flower to fruit, it takes several months for the coffee plant to produce harvest-ready cherries.

What Is a Coffee Tree?

The coffee tree is a shrub or small tree belonging to the Rubiaceae (madder) family. It has oval-shaped, leathery leaves that grow in opposite pairs along the branches. These leaves are dark green and glossy, typical of many tropical evergreen plants. The tree is hardy but prefers shaded, cooler environments and does not tolerate direct sun, drought, or disease well.

Coffee Flowers: The Start of the Coffee Cherry

Around three years after planting, a coffee tree reaches maturity and begins to flower. In early spring—typically March in its native regions—the tree sprouts small, white, fragrant flowers. Each flower has five petals arranged in a spiral pattern, with a pistil that appears to spin around them, resembling a tiny pinwheel. The blooms emit a light, sweet jasmine-like aroma. The flowers grow in dense clusters along the branches.

These delicate flowers last only two or three days before they fall off. After pollination, usually by wind or insects, the fertilized flowers gradually develop into coffee cherries over the next several months.

From Flower to Coffee Cherry

Once the flowers fade, the coffee tree begins forming small green fruits. These immature fruits are classified as drupes—or stone fruits—and are similar in structure to cherries. Initially green, the coffee fruits gradually change color: first to yellow, and finally to a deep, vibrant red once fully ripe. This red, cherry-like fruit is what’s known in the coffee industry as the coffee cherry.

The coffee cherry is roughly 1.5 centimeters in diameter. Its outer skin is smooth, and beneath it lies a layer of sweet, sticky mucilage. Inside, there are two seeds nestled facing each other—that is, two coffee beans. Each coffee cherry usually holds exactly two beans, although rare mutations can produce a single seed called a “peaberry.”

Varieties of Coffee Beans Inside the Cherry

There are three main commercial coffee species grown for global consumption: Typica (often referred to as ‘small bean’ or arabica), along with two larger-seeded types (typically known as ‘medium’ and ‘large’ beans). The smaller-seeded variety (commonly arabica Typica types) generally has lower caffeine but more complex aroma and flavor. The medium and large beans tend to have higher caffeine content and a stronger, less nuanced taste profile.

In commercial blends, it’s common to find a mix of around 70% medium-bean varieties (for caffeine strength) and 30% small-bean types (for aroma). Each of these species and varieties also includes multiple cultivars or genetic variants—anywhere from a handful to more than ten per base type.

The Coffee Plant’s Growing Needs

Coffee trees thrive in mild, shaded conditions. They are relatively cold-tolerant but do poorly under intense sunlight, prolonged dryness, or in disease-prone environments. The coffee cherry, once mature and red, is the only part harvested for coffee production. The fruit contains caffeine, proteins, fats, fiber, and sugars among its nine key chemical components. The seeds themselves are the only parts used to make the coffee we drink.

The flesh of the coffee cherry is rich in natural sugars, which can be processed to create coffee sugar or even fermented into alcohol. Meanwhile, the flowers contain aromatic oils that can be extracted for high-end perfumes and essential oils.

Frequently Asked Questions

What does a coffee bean look like before it is roasted?

Before roasting, a coffee bean is actually a seed found inside a red coffee cherry. Each cherry usually contains two seeds, which are greenish-gray, flat on one side, and oval-shaped. These seeds are covered in a thin, papery silver skin and a thicker parchment layer, all of which are removed during processing before roasting.

How many coffee beans are in each coffee cherry?

Each mature coffee cherry typically contains two coffee beans. The beans sit facing each other inside the cherry. Rarely, a cherry may produce just one rounded seed called a peaberry, which occurs in less than 5% of coffee fruits.

What is a coffee cherry?

A coffee cherry is the small, round fruit that grows on a coffee tree. It is about 1.5 cm in diameter, turns bright red when ripe, and contains two coffee beans. The outer skin is smooth, followed by a layer of pulp, then a sweet mucilage, a parchment layer, and finally the two seeds (coffee beans) inside.

What part of the coffee plant becomes the coffee we drink?

The only part of the coffee plant used to make the beverage is the seed inside the coffee cherry—commonly called the coffee bean. The beans are extracted from the ripe red cherries, processed to remove the fruit layers, dried, roasted, and then ground for brewing.

How long does it take for a coffee tree to produce fruit?

A coffee tree generally begins flowering and producing fruit about three years after being planted. The flowers bloom for just a few days before turning into cherries, which take several more months to ripen to a deep red and become ready for harvest.

Are coffee flowers fragrant?

Yes, coffee flowers have a light, sweet fragrance similar to jasmine. The five-petal white flowers bloom in dense clusters and emit a pleasant scent for two or three days before they fall off the tree.
