[About Coffee Beans: Flavor Characteristics of Sun-Treated Coffee Beans]

Solarization is the oldest way to treat coffee beans in the world, and it is also the easiest way.

Pour the fruit into the tank and sift. The ripe beans will sink to the bottom and the floating beans will be removed.

Then leave it outside in the sun until the moisture content drops below 12%

During this time, the coffee beans should be constantly stirred to prevent mold

Finally put into the machine to remove the peel pulp and sheepskin shell can be bagged.

(Floating beans: mostly stunted beans or overripe beans)

This treatment method has the advantages of simplicity, water saving and low cost.

The disadvantage is that it is easy to mold due to unremoved pulp during the sun exposure process

Or is the degree of dryness caused by fermentation over and produce sour smell.

Sunlight treatment method has tropical fruit, berry and wine flavors, and the taste is mellow and rich in layers.

Suitable for those who love rich fruit flavors.

Why is coffee bean sunburn flavor richer?

Coffee beans will have what kind of flavor, in fact, coffee beans can be processed to see some clues

Today, let's imagine how coffee tastes from the process!

First of all, we must first clarify an idea: processing process = fermentation process

Coffee bean processing is the process of picking coffee cherries from fruit trees and processing them into pre-roasted beans

This process can also be seen as the fermentation process of coffee beans.

Just as wine needs to be well brewed to produce excellent flavor, the process is similar for raw beans,

It is a combination of bacteria and coffee beans fermentation processing, coffee beans can be hidden secret flavor guide out oh!

So what's the secret flavor of solarization?

Sunlight method, simply speaking, is to use the sun to coffee cherries, with pulp, peel dried, so English called Nature

However, this nature processing method seems easy but not simple, and his refinement has also gone through some effort.

Commercial sun treatment is to spread a piece of plastic cloth on the ground and put coffee beans directly on it for sun exposure;

However, the problem lies in the heat transfer and thermal convection instability of coffee cherries. If they are not stirred frequently, there may be problems with excessive heating or uneven fermentation.

(Imagine that the beans on the top are very comfortable, and the beans under them may smell strange.)

In addition, there are many bad strains and pollution on the ground, which will also destroy the flavor of coffee beans.

So traditional sun, there are a lot of flavor, early good beans will not use the sun to process, because people have a bad impression, the price is not high

However, in recent years, the sun method has improved a lot.

Most of the current solarization methods use African elevated sheds, which can effectively block moisture and soil on the ground and increase air convection. The temperature will also be strictly controlled during the sun exposure process, so as not to cause excessive fermentation due to high temperature.

The whole process of solarization usually takes more than 20 days, so that the strains and coffee cherry pulp gradually ferment, so the flavor is sweet, but also with rich tropical fruit flavor.
