If you've had coffee that tasted like red berries, passion fruit, or plum and thought it was flavored, you were almost certainly drinking a Natural coffee. Those notes are real; they're in the bean, and they appear through a process that most coffees in the world never go through: dry fermentation.
It is one of the oldest methods of processing coffee—and at the same time, one of the most demanding. Only producers who control the entire farm can afford to do it well, and it's what distinguishes an authentic single-origin coffee.
The starting point: what is a Natural coffee?
After harvesting, every coffee bean faces a decision: what do we do with the pulp surrounding the seed? There are three possible answers—washed, honey, and natural—and each produces a distinct coffee.
In the washed process, the pulp is immediately removed with machinery. In the honey process, it is only partially removed, leaving some mucilage adhering to the bean. In the Natural process, nothing is removed: the bean is dried whole, with all the pulp, for weeks.
That prolonged contact between the seed and the ripe pulp is what makes all the difference. The fruit acts as a natural fermenter around the bean—and the aromatic compounds of the pulp end up being absorbed by the seed.
What happens inside the bean during dry fermentation
Dry fermentation is a complex biochemical process involving natural yeasts and bacteria present in the coffee pulp. For days or weeks, these microorganisms break down the sugars and acids of the fruit, generating volatile compounds that the seed absorbs.
The result is three distinct effects:
- Generation of new aromatic compounds—esters, alcohols, and acids that would not exist without fermentation. These are responsible for notes of ripe fruit, wine, and red berries.
- Transfer of sugars from the pulp—the bean absorbs the sugars from the fruit, intensifying the natural sweetness perceived in the cup.
- Modification of the acid profile—the organic acids of the pulp transform the acidity of the coffee from something bright and citrusy to something more rounded and fruity.
That's why a Natural coffee almost never tastes like traditional coffee. It tastes like fruit, wine, something that seems impossible to extract from a roasted bean.
Why dry fermentation is so demanding
The problem with natural fermentation is that it can easily go wrong. Very wrong.
Well-executed fermentation produces extraordinary flavors. Uncontrolled fermentation produces serious defects: notes of mold, rancid alcohol, and vinegar. And the line between one and the other depends on variables that the producer must control daily, sometimes hourly.
The critical variables are:
- Strict selection of the fruit—only beans at the perfect stage of ripeness. A green or overripe fruit contaminates the entire lot.
- Temperature and humidity of drying—too humid and mold grows; too dry and fermentation stops.
- Constant turning—the beans are turned several times a day to prevent uneven fermentation. At Hacienda Las Mercedes, we do it manually.
- Time—too short and flavors are missing; too long and defects appear.
- Space—drying is done on African beds or patios, not in machines, because the temperature must be low and constant.
For all these reasons, most coffees in the world are not Naturals. It's safer, faster, and cheaper to make washed coffee. But the result is not comparable.
The sensory profile of a well-made Natural
A properly processed Natural coffee has an unmistakable identity in the cup:
- Aroma—intense, fruity, with notes reminiscent of red berries, young red wine, ripe fruit.
- Body—dense, round, almost syrupy.
- Acidity—fruity and ripe, not citrusy.
- Sweetness—very noticeable without the need for sugar.
- Aftertaste—long, fruity, with an finish that seems more like dehydrated fruit than coffee.
If you try a Natural for the first time, the most common comment is: “this doesn't taste like coffee”. And, in a sense, that's exactly the result the producer was looking for.
Green Hills Natural Coffee
Our Natural Coffee is the most intense and fruity of our regular line, and it is processed entirely at Hacienda Las Mercedes—from selective harvesting to drying on African beds under daily control.
The cup profile is clear: red berries, plum, and passion fruit, with a dense body and a long aftertaste. This is the coffee we recommend when someone wants to know why specialty coffee tastes different from the coffee they know.
Like all natural fermentations, production is limited and depends on each harvest. It is not a coffee that can be manufactured on an industrial scale—nor do we want it to be.
Try the coffee that barely tastes like coffee. Our Natural is processed entirely on the farm, with the control that only comes from producing everything in one place.
