Grinding degree and Flavor description of Kenyan Coffee beans

Coffee entered Kenya in the 19th century, when Ethiopian coffee drinks were imported into Kenya through southern Yemen. But it was not until the early 20th century that the bourbon was introduced by the St. Austin Mission. Kenyan coffee is mostly grown at an altitude of 1500 to 2100 meters and is harvested twice a year. To ensure that only ripe berries are picked, people have to tour the forest and come back about seven times. Kenyan coffee is grown by small farmers. After they harvest the coffee, they first send the fresh coffee beans to the cooperative cleaning station. The washing station sends the dried coffee to the cooperative in the form of "parchment coffee beans" (that is, coffee beans covered with endocarp) to the cooperative ("parchment coffee beans" is the last state of coffee beans before peeling). All the coffees are collected together, and growers charge an average price according to their actual quality. On the whole, this trading method works well and is fair to both growers and consumers.

A total of six concentric circles are needed at this stage. After the smallest flow of water is injected into the center point by hand for 2 seconds, the concentric circle is around the first circle, and then each concentric circle is enlarged 1 turn accordingly. To the fifth concentric circle, about 12.5px away from the wall of the filter cup, all powder layers will be wet to water and washed away. Then, go back to the fourth concentric circle. The third stage will explain in detail how to circle the third lap.

After circling 6 concentric circles, the electronic claim will show that the amount of water is about 70-80 grams (including 31.8 grams of water used for steaming). If it exceeds 80 grams, the flow is too large, and you must practice the smallest flow and circle it. Use this thin water to slowly circle and disperse the powder layer formed by steaming, and all the powder is wet to the water, determining the direction of the taste. The first feeling of drinking coffee is that the taste is distributed to the whole mouth, and every taste bud can feel the coffee, which can improve the cleanliness and sweetness.) This stage of the flow requirements is the lowest, even if you break the flow does not affect the taste, as long as it can be wet to all the powder. If the filter paper is washed on the filter paper during the circle at this stage, the water on the filter paper will be absorbed by the powder layer, because when the fine water flows around, the water absorption rate of the powder layer is slow and the water in the powder layer is not saturated.

On the contrary, hand flushing is popular in China. The water is also injected at the central point, but the flood flows around 2-3 times, and the water in the powder layer is saturated. The large current has a great impact on the powder layer, and many people do not dare to go to the extreme edge, so they can only circle around the center point and the middle part of the filter cup wall. the large water flow will quickly push up the powder layer, and some of the steaming powder layer on the far side will be relatively dry relative to the central point, resulting in insufficient extraction. (taste trend: the first taste of drinking coffee is included in, and the coffee liquid flows directly down to the throat, resulting in a strong taste and easy to have raw and mixed smell.)

You can compare and feel the difference in the direction of the taste.
