Many friends are full of curiosity about the "wet planing method". They want to know the difference between wet planing coffee beans and traditional washing and sun treatment methods. In fact, they have also talked about specific treatment methods before. Today, they will systematically talk about the past and present life of wet planing method.

Sumatra coffee is fascinating with its charming cedar herbal flavor and unique spice flavor, and such a coffee unique on the coffee map, do you know their real growth environment? Sumatra Island is located on the equatorial line, most of the island is covered by tropical rain forest, the annual humidity is 70%-90%, the annual rainfall is 2000 mm, although the volcanic ash soil can make coffee trees grow vigorously, but this humid climate, easy to make coffee fruit moldy, rotten.

Due to the high humidity throughout the year, according to the normal washing method, the drying time will be twice as long as the normal treatment method, and coffee beans in a short time if not dried in time, it is easy to ferment excessive, or produce moldy phenomenon, each change affects the flavor of coffee, so how to deal with coffee fruit, preserve coffee beans, become Sumatra coffee production biggest problem.

● Let's first look at how Sumerians intelligently produce wet-planed coffee beans.

First, remove the outer pulp of the coffee fruit, so that it retains the endocarp and pectin mucus, and put it into a concrete box or plastic bucket for fermentation overnight, which helps to decompose pectin mucus and is easier to remove;

The second step is to clean our coffee fruit. The pectin mucus will be removed in this cleaning. At the same time, this cleaning allows us to obtain coffee beans with only endocarp. After drying them in the sun for 2-3 days, their moisture content will drop to 20-24%, so that the hardness of coffee beans can reach the hardness of separating from endocarp.

Third step, in the case of water content of 20-24%, the coffee beans themselves are soft, even contain more water, while the endocarp is semi-dry, but Sumatra humid climate has not allowed to dry again, at this time we need to use a machine to separate the endocarp from the coffee beans. In this case, peeling the semi-dry endocarp often cannot be completely removed, and there will always be residue. If you peel more, the coffee beans will be damaged. The form of sumatra unique sheep's foot beans, so you buy mantinin coffee beans often have a certain instability;

The fourth step is to continue to dry the coffee beans with uneven peeling of endocarp, and the moisture content continues to drop to 12-13%. During the day, the coffee beans enjoy sunshine, and at night, they are stored in sacks, and continue to ferment under the action of moisture. When drying is completed, the coffee beans can be taken away by buyers.

● The above is the complete processing step of wet planing method. Compared with other processing methods, wet planing method is racing against time. The ultimate goal is to minimize the drying time in high humidity air.

Of course, there is also a key that cannot be ignored, that is, hand-picked beans, good mantning coffee often goes through three hand-picked beans. In such a way as to combat the humidity of the air, Sumatra coffee beans uneven, this time it is the industrious Sumatra people, let us drink high-quality mantinin coffee. Think about how you pick beans when you bake them, and how they have to deal with a whole season of production just to bring you a high-quality mantnin.

● We can see that wet planing can process coffee fruit quickly, and the reason for this is that Sumatra's high humidity and heavy rainfall make coffee farmers have no choice.

Below is a comparison of precipitation and precipitation days between Sumatra and Sidama in 2016.

Looking at the ordinate units we can clearly see that Sumatra's super rainfall is far less than Sidama. Therefore, under such harsh conditions, coffee bean processing is a race against time, against corruption and bacterial infection. Wet planed coffee beans may not look as refined as other coffees, but trust me, when they come across the ocean to you, they come with their own sincerity and high quality.
