A brief introduction to the difference between water washing and sun exposure in front street

Most of the sun treatment methods use the African viaduct, which can effectively block the moisture and soil on the ground and increase the air convection. In the process of sun exposure, the temperature will also be strictly controlled to prevent the high temperature from causing excessive fermentation. The whole process of sun treatment usually takes more than 20 days, allowing the bacteria and coffee cherry pulp to gradually ferment, so the flavor is relatively sweet, but also with rich tropical fruit flavor.

In the washing method, the harvested coffee cherries are peeled and pulped, and the remaining seeds and a layer of residual mucous membrane are thrown into the sink and fermented with water. The whole fermentation time is only about 24-30 hours.

The coffee beans after harvest must enter the treatment program immediately, otherwise they will begin to ferment, making the coffee beans have a bad smell. There are two methods of treatment: "solarization" and "washing", which will cause different flavors. Sun-dried beans have a complete natural mellow flavor, gentle aroma and more gum; washing rules have a good mellow taste, high aroma and lively sour taste. The quality of the water washing method is obviously better than that of the sun exposure method. In the process of water washing, the defective beans floating on the water surface can be easily removed, and the flavor is not easy to appear because the fermentation time is short, and the beans are naked and washed in the sink. Therefore, the water washing treatment will show a clean and flawless taste.

[sun Yega Chuefei]: it is recommended to use 15 grams of powder 91 degrees water temperature, grinding degree BG 6Spene V60 filter cup, water powder ratio 1:15, the first water injection 30g, steaming 25s, the second water injection 1170 grams water cut off, the second water injection to 230g water, not the water in the tail section, the extraction time is about 230g.

[washing Yejia Xuefei]: it is recommended to use 15g powder 91 degrees water temperature, grind degree BG 6Speny V60 filter cup, water powder ratio 1:15, the first water injection 30g, stew 28s-30s, the second water injection 110g water cut off, the second water injection to 230g water, the tail water is not needed, the extraction time is about 230g.
