What is the basic process of making coffee? what is the biggest difference between washing and drying?

The process of making coffee basically includes picking, drying, roasting, grinding and cooking.

There are two kinds of picking, manual and mechanical, because the maturity of handmade coffee beans is uniform, and there is no mildew, and so on, so high-quality coffee beans basically use this method.

There are also two kinds of drying, sun drying and washing. Coffee beans are wrapped in peel, pulp and a thin film called silver skin. Sun-drying is the most economical, simple and oldest method, which is dried in the sun and then peeled off the pulp and silver on the sheller. The disadvantage of this method is that the coffee will stick to the smell of soil. But the flavor can be well preserved. However, with the development of science and technology, we have begun to use dryers to dry coffee fruits.

The biggest difference between washing and drying is that the peel and pulp of the fruit are removed, the coffee fruit is placed in a huge tank, the ripe fruit sinks to the bottom and separated from the floating immature, and then the fruit is crushed by machine. The coffee beans are fermented to remove the slimy fruit oars from the silver skin, and then dried, but the silver skin is also included at this time. When it is exported, the silver skin is removed by a peeling machine, which can retain the original flavor of the beans. This method is usually used for high-quality Arabik.

Roasting can make the ingredients of coffee beans react, convert starch into powdered sugar and acidic substances, and carbonize cellulose to varying degrees. Baking is divided into shallow, medium, deep and extra-deep baking. Generally speaking, the lighter the sour taste, the stronger the sour taste, the deeper the coffee, the more bitter the coffee is, and the darker the color is, the bitterness is very obvious when it is roasted very deep, and there is a light smell of soot.
