What kind of coffee beans are just planted? What is the extract?

Coffee beans basically grow opposite to each other. So one side of the coffee bean will be flat. This kind of coffee bean with one side, we call it "flat bean".

Some coffee fruits grow only one seed (5%-20% of the total), which is due to fertilization or environmental factors, resulting in a serious deterioration of the seed growth on one side, which looks round (in this case, the seeds on the other side will not be produced), this round coffee bean, we call it "round bean".

In the coffee bean selection process (the process of distinguishing the size and picking out the poor quality coffee beans), the "round beans" should be selected from the "flat beans". As the number of coffee beans is rare, they should be sold differently from the coffee beans that they are used to. Coffee beans in Brazil, Blue Mountain and other places are very famous, and the price is higher than that of coffee beans. But for farmers, there should be even coffee beans in a fruit, but only one has grown, which will greatly affect the output of coffee beans, so it is not a happy thing. Coffee fruit (coffee cherries) is oval, coffee flowers fall behind, and the fruit is only the size of a match. it will only grow bigger after 6 to 8 months of growth. The size of the coffee fruit varies according to the cultivation environment and variety. If it is Arabica, the fruit will be the size of 1.5~2cm, with a more cross-sectional diameter of 1 to 1.5 cm, while the fruit of Robasca will be slightly smaller than that of Arabica.

When the fruit is ripe, the pulp becomes very soft. The flesh of the coffee fruit is not thick, but it tastes sweet. In the harvest season, we can often see the children who come to help put the flesh into their mouths to eat.

After peeling off the pulp, you will see that there is a thin skin on the seed, which is the endocarp of the coffee bean, and the seed wrapped in the endocarp is also called "parchment coffee bean". There is also a sticky layer on the surface of the inner pericarp, which is called pectin. If you want to take out the coffee beans, you have to remove the pulp, pectin and endocarp.

After removing the peel, there are two coffee beans inside.
