What is the difference between G1 and G2 coffee beans? what are the grading criteria for Ethiopian coffee beans?

The difference between G1s and G2s.-Why are they graded? what's the purpose?

The peel, pulp and mucous membrane are removed by washing and fermentation. farms that use the washing method must build washing ponds and be able to introduce an endless supply of live water. During the treatment, the finished beans are put into the pool and passed back and forth, using the friction of beans and the power of running water to wash the coffee beans until smooth and clean. After washing, at this time, the coffee beans are still wrapped in the pericarp with a moisture content of 50%. They must be dried to reduce the moisture content to 12%, otherwise they will continue to be mellow, moldy and rotten. The better treatment method is to use sunlight drying, although it will take 1 ~ 3 weeks, but the flavor is very good and very popular.

Yega Xuefei is a small town, 700-2100 meters above sea level, synonymous with Ethiopian boutique coffee. It has been a wetland since ancient times. The ancient saying "Yirga" means "settle down" and "Cheffe" means "wetland". The mode of production and flavor of coffee here are so outstanding that Ethiopian coffee farmers compete to take pride in the flavor of their coffee, making it the most famous coffee producing area in Africa.

Yejassefi's coffee trees were planted by European monks (a bit like Belgian monks growing wheat to brew beer) and were later transferred to farmers or cooperatives. Yejia Chuefei is actually constructed by surrounding coffee communities or cooperatives, including Edido Idido, Hafusa Harfusa, Hama Hama and Biloya near Fog Valley Misty valley, all washed with water, but there are also a small number of off-product beans engraved with sun to enhance the charming fruit aroma and mellow thickness. These mountain villages are foggy, like spring all year round, with a gentle breeze in summer, cool but not hot, rain but not damp, and no cold damage in winter, giving birth to a unique regional flavor of citrus and flowers. Coffee trees are mostly planted in farmers' own backyard or mixed with other crops in the field, the yield per household is not much, it is a typical rural coffee. Yega Xuefei won the prize beans almost from the above-mentioned coffee villages and communities.

1. Under the same treatment, sun beans will take away the obvious dry aroma of red wine, while washed beans are citrus honey fruit aromas.

2, both products will have obvious sour taste, similar to lemon and citrus fruits, but sun beans are more mellow. The red wine flavor in the dried beans is not obvious in the finished product.

3, the acidity of the washing treatment will be brighter, like citric acid, the taste will be more delicate, the citrus flavor will be more obvious; the sun will be more mellow, commonly known as the coffee will be more bitter, the taste will be much stronger.

4. Sun-dried beans are more expensive in price.
