The distinction between coffee beans

The color should be shiny. Also take into account the changes in color after harvest. The shape requires that the particles are uniform and neat, and there should be no deformed beans. The taste should have the fresh and fragrant smell of raw beans. There is no need to judge the personalized taste of raw beans, but to make sure it is a fresh crop. Raw beans should not have a peculiar smell (fermentation, mildew, medicine, soil, etc.).
