After the coffee cherry is picked from the tree, the exocarp pulp and pectin are removed, a process called raw bean treatment.

Raw coffee beans are treated in different ways, and they largely determine the taste and quality of coffee!

Today we will talk about the advantages and disadvantages of each major treatment method!

The strong aroma of wine is exposed to the sun.

This is the most primitive, simple and oldest treatment of coffee. According to relevant literature, Arabs began to use coffee bean sun treatment of coffee fruit as early as 1000 years ago in the 11th century.

Treatment process

First pour the coffee beans into a large tank, the underdeveloped inferior beans will float on the surface, pick up the ripe and full fruits that sink to the bottom of the water, lay them in the sun, and often turn them over to pick out defects.

When the water content in coffee beans is reduced to 10%-14%, the peel pectin can be knocked off with a sheller, and the whole coffee bean tanning method is complete.

Shortcoming

The sun drying of coffee beans depends entirely on the weather, and the dryness of coffee fruits is difficult to control. If the sun is not clean, it is easy to mix with impurities. In the process of the sun, the pulp of the coffee fruit has not been removed, so it is often moldy and rotten. Therefore, in the view of many people, the quality of sun-exposed coffee beans is not controllable and the level is not too high.

Advantages

Except for the first step of using water to filter out inferior beans, the coffee bean solarization method no longer requires any water, and can be used repeatedly. In areas where water resources are not abundant, this method is simply awesome.

And because sun-dried beans have irreplaceable special flavor, some excellent farms begin to take sun-dried beans seriously, such as putting them on shelves to prevent pollution and fine selection, so today we can see a lot of high-quality sun-dried coffee beans.

Flavor

Although the sun-cured beans are uneven in appearance and different in color, because the coffee beans ripen naturally inside the fruit and are not disturbed by the external environment, the sun-cured coffee beans have a stronger flavor, wine-like fermented taste and sweet taste.
