After the coffee fruit is actually harvested, it needs to go through a series of complex processing procedures, and finally after baking, it will become the coffee ripe beans you see. Although many people have drunk coffee, they don't know what the coffee fruit looks like.

Fruit picked from a coffee tree (also known as coffee cherry Coffee Cherry).

Coffee beans are actually the seeds inside the coffee fruit. In the outer layer of the seed, there are exocarp, pulp, pectin, endocarp and silver peel and other structures, and the purpose of processing is to remove these external structures in order to obtain internal coffee seeds.

Sun treatment (natural process) can be said to be the earliest way to treat coffee beans.

After picking the coffee fruits from the fruitful coffee trees, spread them all flat on the ground and wait for the sun to dry the skin and flesh of the coffee fruits.

The process of drying coffee beans in the sun is similar. In some areas, due to lack of water resources, long sunshine and strong and free sunshine, it is very economical for them to use the sun to deal with the harvested coffee beans.

Does sun-dried coffee beans taste strange?

Early coffee farmers did not have the concept of quality control, nor did they have a very good skill value. after the coffee trees bear fruit, regardless of the maturity of the coffee beans on the branches, they pull them out regardless of whether they are green or red (on the one hand, they may also be reluctant to be eliminated). And then spread it directly on the ground in the yard at home to dry. If you think it's almost like going through it, you may not see the broken part, or you may be reluctant to throw it away. Poultry and livestock are running around, and when they feel almost dry, they are stored in the warehouse. It seems like a pleasant farm scene-- but in such a process, to maintain the quality of coffee beans every time, it really depends on luck, and it is easy to produce strange flavors.

In the early days, sun-dried beans had a lot of miscellaneous flavor and often drank some "surprises", so some people dared not compliment, in part because of the "imprecision" of this process.

However, with the progress of the times, even in the remote coffee producing areas of Africa, farmers will receive a lot of advice and new technical knowledge from sales channels, so the current sun treatment methods are completely different from each other!

So how does the current sun treatment work?

First of all, when coffee farmers harvest the fruits, experienced harvesters pick the fully ripe coffee fruits one by one with their bare hands. Because the fully ripe coffee fruit is as red as a cherry and belongs to the berry category, we call it "Coffee Cherry coffee cherry". After collecting the red coffee cherries, farmers will first go through a screening process, pick out the defective coffee cherries manually, and then send them to the exposure ground to dry.

African Raised Beds Solar treatment method

When drying coffee beans in many areas, a kind of "African-style high scaffolding" is used to put the coffee beans on the high scaffolding for sun treatment. the biggest advantage is that it can avoid the problems caused by directly drying on the ground. for example, soil smell, pollutants. And so on, it can also be expanded almost infinitely without the restriction of the slope topography. When workers work, they don't have to bend over all the time, they will be more comfortable and convenient, and they can improve their work efficiency.

When drying coffee, if the weather is bad, the fruit is easy to get wet, and if it is wet at night, you should also receive the coffee fruit indoors; if you don't take good care of it, the beans are easy to pollute and mildew, taste rotten, and are very bad for your health. In the process of exposure, also remember to do the action of stirring every once in a while, so that the upper and lower layers of coffee beans can be evenly exposed, and pick out the defective beans over and over again, it is really hard and hard work!

The secret of rich flavor and delicious taste.

The cost of drying beans in the sun is much lower than other treatments, and it saves resources. It is a favorite method in many countries with low rainfall.

During the sun treatment, the whole fruit is exposed to nature with skin and flesh, and the time of drying the beans depends on the weather conditions at that time, ranging from two weeks to a month. Until the water content of the beans is reduced to about 10-12%, the dried and hard fruits will be put away and the coffee beans can be taken out.

The appearance of the sun-dried beans is yellow, with a fragrant and fermented smell from the pulp and pectin concentrated in the seeds by the sun. Sometimes the appearance of beans will be a little missing corners, this is because when shelling, the sheller removes the dry pulp and sheep skin at one time, which will inevitably hurt the beans a little.

The hard work of the sun will not be wasted, good quality sun beans, the sugar of the whole ripe fruit is condensed into the beans bit by bit by sunlight, the fruit aroma is very rich, and the taste is mellow, the sweetness is high, and the acidity is not as sharp as washed beans; the special fermented taste of sun fruit makes many people fall in love with it after drinking it several times.

In the Yemeni mocha in the former street, for example, the ancient law sun gave this bean an indescribable and wild flavor, which may not be accustomed to at first, but once you get used to it, you will feel what a magical flavor it is. Without this wild ancient flavor, you will feel that something is missing.
