The Botanical Difference: Apples and Oranges
Botanically, coffee cherries and true cherries are unrelated, belonging to different plant families. Coffee cherries are the fruit of the Coffea plant in the Rubiaceae family, which also includes gardenias. True cherries come from the Prunus genus within the Rosaceae family, which contains other stone fruits like peaches and plums.
Both are classified as drupes or stone fruits because they contain a single seed. However, their similarities end there; their common name comes from a superficial resemblance in color and size.
Anatomy of a Coffee Cherry
A coffee cherry has several distinct layers surrounding the seeds, which are the 'beans'. These include the outer skin (exocarp), a thin pulp (mesocarp), a slimy layer (parenchyma/mucilage), a paper-like layer (endocarp/'parchment'), the silver skin (spermoderm), and typically two seeds (the 'coffee beans'). A single, rounded seed is known as a peaberry.
The Journey from Fruit to Brew
The processing of coffee cherries is vital for coffee production, typically focusing on extracting the seeds. Various methods are used, influencing the final flavor. Common methods include the dry process (sun-drying the whole fruit), the wet process (removing pulp before fermentation), and the honey process (leaving some mucilage during drying).
Comparison Table: Coffee Cherries vs. Real Cherries
A comparison highlights key differences:
| Feature | Coffee Cherries (Coffea) | Real Cherries (Prunus) | 
|---|---|---|
| Botanical Family | Rubiaceae | Rosaceae | 
| Fruit Type | Stone fruit (drupe) with two seeds (pits) | Stone fruit (drupe) with a single pit | 
| Primary Purpose | To produce coffee beans (the seeds) | Eaten fresh, cooked, or processed as fruit | 
| Flesh (Mesocarp) | Thin, sweet, with limited edible pulp | Thick, juicy, and highly prized for flavor | 
| Flavor Profile | Sweet, melon or red currant notes in the pulp | A range from tart to sweet and rich | 
Are They Edible? The Taste and Nutritional Profile
Coffee cherry pulp is edible and used for cascara, a tea from the dried skins. The fruit pulp is rich in antioxidants. However, due to little flesh, they aren't typically eaten raw like true cherries.
Conclusion: A Name, Not a Family
Despite the name, coffee cherries are not botanically 'real cherries'. They are the fruit of a different plant family, with unique anatomy and purpose. The coffee 'bean' is the seed, and the rest is often a byproduct of creating the popular beverage. This stone fruit highlights that a name doesn't always reflect botanical reality.
