What is a coffee cherry?
A coffee cherry is the fruit of the coffee plant. It holds, in most cases, two seeds lying flat side to flat side, and those seeds are the coffee beans. Around them sit a skin, a sweet pulp, a sticky layer called mucilage, a papery parchment and a thin silverskin. Coffee is the seed; the cherry is everything a farm removes to reach it.
The layers, outside in
| Layer | Botanical name | What happens to it |
|---|---|---|
| Skin | Exocarp | Pulped off, or dried with the fruit in a natural |
| Pulp | Mesocarp | Pulped off; dried skin and pulp are sold as cascara tea |
| Mucilage | Part of the fruit flesh | Fermented off in washed coffee, left on in honey coffee |
| Parchment | Endocarp | Dried around the bean, then hulled off at the mill |
| Silverskin | Seed coat | Mostly flakes off as chaff in the roaster |
| Seed | Mostly endosperm | Becomes green coffee, then roasted coffee |
Layer names from Wikipedia's Coffee bean article. The seeds are called beans for their shape, though they are not true beans, and like a Brazil nut they are mostly endosperm.
Now and then a cherry grows only one seed, round instead of flat sided. That is a peaberry, and Wikipedia puts peaberries at around 10 to 15 percent of all coffee beans.
From flower to ripe fruit
An arabica shrub first flowers three to four years after planting, with small white, fragrant blossoms. Each flower that sets becomes a green cherry that swells and ripens to red or yellow. Wikipedia's coffee bean article notes the plant needs more rain while the fruit develops and less as it ripens, and ideal growing temperatures between 24 and 30°C (75 and 86°F).
Picking is almost always by hand. In selective picking, workers take only the ripe cherries and return for the rest later. In strip picking, the whole branch is stripped at once, and the unripe and overripe fruit has to be sorted out afterward. Wikipedia says selective picking yields higher quality coffee, because each cherry comes off at its ripest.
How the cherry shapes the flavor
How much of the fruit stays on the seed while it dries is the biggest choice a farm makes after picking. Wikipedia's processing article describes the three main methods, and what it says about each:
| Method | What stays on while drying | What Wikipedia says |
|---|---|---|
| Washed | Nothing but the parchment | The most common method; fermenting under water is said to emphasize acidity and aroma |
| Honey | Some or all of the mucilage | Mellow and sweet, mild acidity, fruit or honey notes |
| Natural | The whole cherry | The oldest method; it needs dry weather at harvest, and nearly all robusta is processed this way |
Tasting the cherry in Montana-roasted coffee
A natural process coffee is the easiest way to taste the fruit, because the seed dried inside the whole cherry. These Montana roasters listed natural, honey or anaerobic coffees on their own sites when we checked on September 27, 2026:
- Ghost Town Coffee Roasters, Bozeman: an Ethiopia Guji natural, next to a washed Rwanda Sholi for comparison.
- Rockford Coffee, Bozeman: an Ethiopia Guji natural and a Nicaragua La Bastilla natural, plus washed coffees from Papua New Guinea and Guatemala.
- Drum Coffee Roasting, Missoula: an organic Rwanda Sholi natural, and a Costa Rica Santa Elena in both honey and washed form.
- Revel Coffee, Billings: natural Ethiopians including Buku Abel, and a Costa Rica Montano Anaerobic.
- RamsHead Coffee Roasters, Shields Valley: natural Ethiopians from Werka Nensebo and Guji, and anaerobic coffees from Ethiopia, Colombia and Rwanda.
Buy a natural and a washed from the same Montana roaster and brew them side by side: the difference in the cup is the cherry. It is a cheap lesson in coffee, and the money goes to a roastery in Bozeman, Missoula, Billings or the Shields Valley. More on why local roasters matter.
The cherry and the club
There is no processing switch in the plan builder, but Single origin is the setting that brings named farms and methods: the bag and our packing slip tell you where it grew and, when the roaster says, how it was processed. Set a light roast with it to keep the fruit in front. Start on the home page. $16.99 a 12 oz bag. First bag free, you pay $7.99 shipping. Then $16.99 a bag. "Your ratings steer the next bag," so rate a natural high and more fruit follows.
