Comparison of Qianjie-Yejiaxuefei Coffee treatment and sharing of brewing parameters

Raw beans are treated differently.

Washing treatment method

The peel, pulp and mucous membrane are removed by washing and fermentation. first, the coffee beans are washed to clean. after washing, the water content of the coffee beans reaches 50% and must be dried so that the moisture content is reduced to 12%, otherwise the coffee beans are exposed to the air. contact with the air to continue to grow mellow, will become moldy and rotten, the most timely treatment method is to use sunlight drying, you can get a particularly good flavor, fragrant Yega.

The washing method will have a good mellow taste, a high concentration of floral fragrance and a lively and soft sour taste. Yega has a distinctive style, and the flavor of citrus and floral flavor in the coffee is irresistible to coffee fans.

Yejia Xuefei sun treatment method

The fruit is not peeled after picking, at the beginning of the sun-drying process (the oldest existing treatment), the process of drying and dehydration usually lasts for a month, and the method of treatment is to ensure that the coffee does not lose its flavor and is not infected. Sun-dried beans drink with a complete natural mellow, gentle aroma and more sugar.

Observe from silver skin

In the process of processing, the refined washing method usually removes the silver skin from the coffee beans, showing a special luster, but the dry and refined method (sun-drying method) only takes off the coffee shell, and the silver skin is still intact.

The difference between raw beans: generally washed raw beans are turquoise, while sun-washed raw beans are yellowish green.

[sun Ye Jia Xuefei Red Cherry]: it is recommended to use 15g powder 91 degrees water temperature, V60 filter cup, water powder ratio 1:15, the first water injection 30g, stew 30s, the second water injection 120g water cut off, the third water injection to 225g water, not the water at the end, the extraction time is about 2RV 05s.

Gift of knowledge: there are relatively more silver skins on the outside of beans in the sun, and they take off more thoroughly when baking, so they are relatively less in grinding; there are more silver skins in the beans washed in water, which will remain after baking and appear more during grinding. Of course, it is directly related to the baking degree. The deeper the baking, the cleaner the silver skin will take off.

Gift of knowledge: because the color of coffee fruit is ultimately determined by the recessive genes in the pollen grains, there are both yellow genes inclined to yellow bourbon and red genes inclined to red bourbon in the pollen grains to be crossed, and these are all recessive genes. It is very easy to interfere with each other, so pink bourbon is a very rare variety.
