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. Mellow taste is an important condition of espresso, which will produce a mellow and smooth feeling as strong as wine. Espresso lovers can increase the weight of sun-dried beans; water-washed beans are as clean as clear wind chimes because of less miscellaneous smell. In addition, washed beans have a good sour taste, which is the main source of sweetness in espresso.

1 Skin/Pulp: the outermost layer of the coffee bean is covered with berry-like skin and pulp. In addition to the natural sun method, coffee beans treated by other methods must remove the skin and flesh within a few hours after picking. Similar to the cherries we often eat, the difference is that when we eat cherries, we mainly eat the pulp and peel of berries. For coffee, peel and pulp are important by-products. In some places, people use the peel and pulp of coffee to make tea. People in the industry used to call the peel and pulp of coffee "Pulp". The machine used to remove the pulp is called the "desizing machine".

Mucous membrane (Mucilage): under the peel and pulp, a layer of sticky mucus tightly wraps the coffee beans. Because this mucous membrane is extremely sticky and high in sugar, it is used to call it "Honey". Not only coffee, but also many fruits have a layer of mucus inside.

Parchment (Parchment): inside the mucous membrane, a thin film of cellulose wraps the coffee beans. After drying, the film looks like parchment, hence the name.

4 Silver skin (Silver Skin/Chaff): there is a thinner film inside the parchment that covers the coffee beans. Because the color is glossy and silvery, people used to call it "silver skin". This layer of silver will fall off during baking. Usually when you grind the coffee, you find some silver crumbs in the coffee powder. These crumbs fail to match the coffee when baked.
