Which part of the fruit is coffee? the structure of coffee fruit.

Arabica coffee is more difficult to grow, they like mild days and colder nights, too cold, too hot, too humid climate can be fatal to it. Coffee trees in Arabica need to be planted on sloping slopes at high altitude. they grow luxuriantly in the highlands (600-1800 meters) and require special climatic conditions-the average temperature throughout the year is about 20 degrees Celsius and there is plenty of rainfall without frost. Only more than 50 countries in the world have such conditions, all of which are about 160 kilometers north and south of the equator. Its harvesting must be carried out manually, which is more difficult. However, due to the excellent aroma, balanced taste and low caffeine content of Arabica coffee beans, the actual planting amount accounts for about 70% of the total coffee planting.

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.

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 this is not a happy thing.
