The production and processing of coffee beans the Panamanian Jade Manor

1. Skin/Pulp: the outermost layer of coffee beans 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".

two。 Mucous membrane (Mucilage): under the skin and pulp, a thick layer of 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.

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

4. Silver Skin/Chaff: there is a thinner film inside the parchment that wraps 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 are the silver skins that fail to peel off the coffee beans during baking.

5. Coffee beans: each fruit contains 2 coffee beans (except for a single pod bean Peaberry. The fruit of this kind of coffee contains only one coffee bean. Normally, 5% of each batch of coffee beans is a single pod. Coffee beans can be roasted after drying and treatment.

1. Natural sun treatment: retain all substances

two。 Honey treatment: remove the peel and pulp and retain some or all of the mucous membrane (honey)

3. Washing method: the peel, pulp and mucous membrane are removed by washing and fermentation. This method is also known as the complete washing method (Fully Washed). Washing is the most common way to treat Arabica coffee beans in most coffee-producing countries in the world. Some areas also use advanced high-pressure washing machines to clean the peel, pulp and mucous membrane of coffee beans, so fermentation is no longer needed. This method of using a high-pressure washing machine to treat coffee beans is called "natural washing (Pulped Natural)".
