Natural Process: The Original Coffee Processing Method
The natural process can be described as the most ancient method of coffee bean processing.
After coffee cherries are picked one by one from heavily laden coffee trees, they are all spread evenly on the ground, waiting for sunlight to dry the moisture from the skin and pulp of the coffee fruit. Once dried, the processing is complete.
Anatomy of a Coffee Cherry
The structure of a coffee cherry from outside to inside consists of the exocarp (outer skin), mesocarp (pulp), mucilage layer, endocarp (parchment), silver skin, and coffee embryo (bean). Therefore, coffee beans undergo various processing methods before becoming green beans for export.
Characteristics of the Natural Process
The natural process involves directly placing coffee cherries under the sun for exposure. When the moisture content of the coffee beans drops below a certain level, machines are used to remove everything from the exocarp to the endocarp at once. The advantage is richer flavor, while the disadvantages include more defective beans and the need for larger space.
The Reward of Natural Processing
The effort of natural processing is not wasted. High-quality natural processed beans have the sugar from fully ripe fruits gradually concentrated into the beans by sunlight, resulting in intense fruit aroma, rich body, high sweetness, and less sharp acidity than washed coffee. The special fermentation flavor of naturally processed coffee makes many people fall in love with it after just a few tastes.
Example: FrontStreet Coffee's Natural Yirgacheffe
Taking FrontStreet Coffee's Natural Yirgacheffe [Berry Orchard] as an example, the natural processing gives this coffee intense fermented berry aroma, making it very sweet and fruity when tasted. Compared to coffee, it's more like a glass of fruit wine.
