Coffee processing method: Natural: The charm of flavor nurtured by nature
The processing method is one of the factors that greatly influences the flavor of coffee. Among these, the "natural process" has been gaining attention in recent years. In this article, we will introduce in detail the characteristics and benefits of the natural process, the flavor trends, and how to enjoy coffee beans processed using the natural process.
What is the natural method?
The natural method is a processing method in which harvested coffee cherries are dried along with the pulp. It is also called the "dry process" because it uses very little water, and has been traditionally used in Ethiopia, where coffee was first discovered, and in Brazil, which has a dry climate.
Compared to other refining methods such as the "washed method (wet)" and the "honey method (semi-washed)," this method is characterized by its extremely simple process, yet is likely to produce a unique and distinctive flavor .
Natural manufacturing process
The natural process involves the following steps:
-
harvest
Fully ripe coffee cherries are harvested by hand, one by one. Careful selection is required, as uneven ripeness can result in uneven flavors.
-
Drying
Once harvested, the cherries are left to dry in the sun on African beds or concrete, which takes 2-4 weeks and requires frequent stirring to prevent rotting and mold.
-
Pulping
Once completely dried, the pulp and husk are removed and the green beans are finally extracted.
By drying the beans slowly with the pulp still attached, the sweetness and aroma of the fruit is slowly transferred to the beans, creating a unique flavor.
Flavor unique to natural manufacturing methods
The greatest appeal of natural brewing is its fruity and sweet flavor . It has a juicy aroma reminiscent of fruits such as berries, cherries, and mangoes, and a rich, full-bodied flavor. The addition of fermentation nuances can also give it a complex flavor similar to wine or spirits.
However, natural coffee is very difficult to control during fermentation and drying, and improper processing can easily result in off-flavors (unpleasant flavors). For this reason, high-quality natural coffee requires careful attention during the refining process.

Who is this recommended for?
Naturally brewed coffee is especially recommended for the following people:

Tips for enjoying natural coffee beans
To bring out the vibrant and unique flavor of naturally brewed beans, the following brewing method is best.
-
Choose a light to medium roast
Light roasting brings out the fruitiness and aroma. The taste changes greatly depending on the degree of roasting, so choose according to your preference.
-
Carefully extracted by hand drip
We recommend using extraction methods such as paper drip or Aeropress to bring out the flavor more delicately.
-
Pay attention to temperature control
Water that is too hot will cause the delicate aroma to disappear, so extracting with water at around 85-90°C will bring out the unique natural flavor more.
summary
The natural method is a fascinating processing method that, while simple, is incredibly profound and brings out the unique characteristics of coffee to the fullest. Naturally processed coffee, with its fruity sweetness, gorgeous aroma, and complex flavor, is truly a "gift of nature."
