What Is a Coffee Cherry? From Fruit to Bean
Share
A coffee cherry is the small, round fruit of the coffee plant, and the coffee bean is the seed inside it. Each ripe cherry usually holds two seeds wrapped in several layers: a thin outer skin, a little sweet pulp, a sticky mucilage, a papery parchment shell and a delicate silverskin. Coffee only becomes the brown bean you know after those layers are removed and the green seed is roasted.
It is easy to forget that coffee starts as fruit. Here is a layer-by-layer tour of the coffee cherry, how it ripens, and how farmers get from fruit to bean.
From Flower to Coffee Cherry
Coffee trees produce clusters of small white flowers with a sweet, jasmine-like scent. After pollination, each flower can develop into a cherry. The fruit starts hard and green, then slowly swells and changes color over several months.
Most varieties ripen to a deep red, but some ripen yellow, orange or even pink, depending on their genetics. Yellow Bourbon, for example, is named for its yellow ripe fruit. Because cherries on the same branch ripen at different times, harvest timing is one of the biggest factors in quality.
Coffee grows mainly in tropical highlands between the Tropics of Cancer and Capricorn. Our guide to the coffee belt explains where and why.
Coffee Cherry Anatomy: Layer by Layer
Botanically, the coffee cherry is a drupe-like fruit, similar in structure to a cherry or plum but with very little flesh. From the outside in:
- Skin (exocarp). The thin, smooth outer skin that turns red or yellow when ripe. It protects the fruit and is the part people see on the tree.
- Pulp (mesocarp). A thin layer of sweet, fruity flesh just under the skin. There is not much of it, but it has a pleasant, slightly floral sweetness when you taste a ripe cherry.
- Mucilage. A slippery, sugary, pectin-rich layer clinging to the parchment. It is technically the inner part of the pulp, and how farmers handle it shapes washed, honey and natural coffees.
- Parchment (endocarp). A thin, papery hull that encloses each seed. Coffee is often dried and stored “in parchment” to protect the seed.
- Silverskin (spermoderm). A very thin, shiny film hugging the seed itself. Some of it remains on green coffee and flakes off as chaff during roasting.
- Bean (endosperm and embryo). The seed. The endosperm is the food store we roast and brew, and the tiny embryo is what would sprout into a new coffee plant.
The Layers at a Glance
| Layer | Botanical name | What it is like | What happens to it |
|---|---|---|---|
| Skin | Exocarp | Thin, red or yellow when ripe | Removed by pulping, or dried on in natural process |
| Pulp | Mesocarp | Thin, sweet flesh | Removed with the skin; skins and pulp can be dried as cascara |
| Mucilage | Inner mesocarp | Sticky, sugary, pectin-rich | Fermented and washed off, or left on in honey process |
| Parchment | Endocarp | Papery hull | Removed at the dry mill (hulling) |
| Silverskin | Spermoderm | Very thin film | Partly removed by polishing; the rest becomes chaff |
| Bean | Endosperm | Hard, green seed | Exported, roasted and brewed |
Two Seeds, One Seed and Odd Exceptions
Most coffee cherries contain two seeds that grow facing each other, which is why a typical coffee bean has one flat side. Occasionally only one seed develops. That single seed grows round and is called a peaberry. Rarer still, a cherry can contain three seeds or seeds that are misshapen, which are usually sorted out.
The seeds make up only a small fraction of the cherry’s weight. A lot of fruit is needed to produce a bag of coffee: depending on the farm and process, roughly 100 kg of fresh cherries yields something like 12–20 kg of export-ready green coffee.
From Fruit to Bean: How Processing Removes the Layers
After picking, the cherry has to be stripped down to the green seed. The method chosen has a big effect on flavor.
Washed (wet) process
Cherries are pulped to remove skin and pulp, then the mucilage is broken down, often by fermenting in tanks, and washed away. The parchment-covered seeds are dried. Washed coffees tend to taste clean and bright.
Natural (dry) process
Whole cherries are dried in the sun, often on patios or raised beds, before the dried fruit and parchment are hulled off. Contact with the fruit during drying can give the bean intensely fruity, sometimes winey flavors, as in our Ethiopia Natural.
Honey process
The skin is removed but some or all of the mucilage is left on during drying. The result often sits between washed and natural, with extra sweetness and body.
Wet-hulled
Common in Indonesia, this method removes the parchment while the bean is still fairly moist, which contributes to the earthy, heavy-bodied character of many Sumatran coffees. Our article on Sumatra coffee explains it in detail.
In every case, coffee is dried until the beans reach roughly 10–12% moisture so they can be stored and shipped safely.
What Happens to the Rest of the Coffee Cherry?
- Cascara: dried skins and pulp can be steeped into a fruity drink. In Yemen, a spiced husk drink called qishr has a long tradition.
- Compost and fertilizer: pulp is often returned to the farm to enrich the soil.
- Chaff: the silverskin that flakes off during roasting, which roasters collect and discard or compost.
Can you eat a fresh coffee cherry? Yes, farmers often taste them to judge ripeness. The flesh is thin and sweet, and most of what you bite into is seed and parchment.
Coffee Cherry FAQ
Is a coffee bean really a bean?
No. It is the seed of the coffee cherry. It got the name “bean” because of its shape, but botanically it is not a legume.
What color is a ripe coffee cherry?
Most ripe coffee cherries are deep red, but some varieties ripen yellow, orange or pink. Pickers judge ripeness by color and firmness, avoiding green and overripe fruit.
Does coffee cherry have caffeine?
Yes, the fruit contains some caffeine, but the seed is where most of it is concentrated. Drinks made from the dried fruit, such as cascara, generally have much less caffeine than brewed coffee.
Why is coffee called green before roasting?
Once the fruit layers and parchment are removed, the raw seed is a pale green or blue-green color. Roasting turns it brown and develops its aroma and flavor.
Taste the Fruit in Your Cup
Understanding the coffee cherry helps explain why processing changes flavor so dramatically. Taste it for yourself by comparing a fruit-forward natural like Ethiopia Natural with a classic Central American cup such as Costa Rica, or explore our single origin coffees. Every Feel Espresso order is roasted 1–5 days before delivery, so the journey from fruit to cup ends with a fresh bag at your door.
