The difference between water washing treatment and sun treatment of raw coffee beans

For a coffee bean, is it better to wash in water than in the sun, or is it better in the sun than in water? At least before I know it, I disdain to wash beans with water. I always feel that the sun is better than washing, and the sun is a little higher. So, in fact, it is a matter of opinion which is better for the two kinds of raw coffee beans. This time, the editor also introduces the difference between solarization and washing for the two kinds of raw beans. I don't know if this article will make you more firm in your choice, or will it make you want to try something else?

The difference between solarization and washing in the treatment of coffee and raw beans

Sun treatment:

As the name implies, the sun treatment method can be simply understood as: after the raw beans are picked and separated by raw and cooked beans, they are spread in the drying farm and dried naturally. Generally after 2-4 weeks, when the water content of the coffee bean is less than 12% and hardens, you can use the sheller to knock off the dry hard fruit shell and sheep skin to take out the coffee bean, the process is simple and rough. This method is basically used in Ethiopia that we are familiar with.

Because the beans are naturally dried in the flesh, the pectin sugar on the shell beans can seep into the coffee beans, making the beans have higher sweetness and mellow thickness, but the sun treatment is most afraid of the humid climate, rain and moisture, so the climate is the key factor whether the sun method can be adopted or not. Therefore, it is generally relatively backward, and most of the producing areas that do not have funds for water washing equipment use this method, which also causes the production of sun-dried beans to be very unstable. Usually we come into contact with more sun beans for Ethiopia's Sidamo, Yega snow coffee, Yemeni mocha and so on.

Washing treatment method:

Washing treatment is the most popular treatment method at present, represented by Central and South America (except Brazil). Washing treatment is the most technical method in the extraction of raw beans, and its cost is also the highest. generally, it takes 2-10 kg of clean water to get 200 grams of coffee beans. For countries rich in water resources in Central and South America, this method can be used as the main way to extract raw beans, while in Africa, the method of washing treatment is relatively extravagant. Water washing soy mellow flavor and bright feeling is better, no miscellaneous smell, no soil smell which is difficult to avoid in the sun treatment.

The process of washing treatment:

Put the coffee fruit in a large water tank to screen the floating beans (ripe coffee fruits will sink to the bottom, immature or rotten ones will float on the water surface)-remove shell beans through pulp sieving machine-wash and ferment, remove pectin-1-3 days later, remove and clean-dry.

Water washing treatment has developed rapidly in recent years, and more and more technologies have made the products more excellent. it is the most commonly used method for the treatment of high-quality coffee beans at present. The coffee beans treated by water washing have pure flavor, low miscellaneous taste, and the best fruit aroma and sour taste. The only defect may be that the sweetness is not as good as that of sun treatment.
