How many coffee beans can a coffee tree produce?-introduction to the origin and varieties of coffee beans.

One of the characteristics of a coffee tree is that its fruit can bear fruit several times a year, and another is that flowers and fruits (also known as cherries) coexist at different stages of ripening. The whole coffee harvest is swayed by the vagaries of nature. If the fruit is too ripe, the beans in it will rot. If it is not ripe enough, the beans picked will not ripen by themselves. So bean pickers often go back to the same tree several times to find ripe fruit-it takes only 2 pounds to go back and forth several times, and a typical Arabica coffee tree produces less than 5 kilograms / 11 pounds of fruit in a year. can be made into about 1 kg / 2.2 pounds of coffee beans.

Most of the coffee harvesting in the world is selected by hand, so it is a labor-intensive and seasonally intensive process. Since there are both flowers and fruits on the same branch, the index finger and thumb of the collector are the best tools for collecting ripe berries. Scraping the fruit off a whole branch by hand or using an automated harvester can't tell ripe berries from green berries.

In the washing type, the harvested fruit is poured into the sink, the floating matter is removed, the fruit in the water is moved to the pulp removal machine, the skin and pulp are removed, and then put back into the tank to remove the floating matter, the "core" in the water is poured into the fermentation tank, soaked for half a day or one day, the colloid on the surface of the fermented bean is removed, washed, dried or mechanically dried, and the endocarp is removed on the peeling machine to become commercial raw coffee beans.

The advantages of washing type: coffee beans have good luster, less foreign bodies, and slightly better sour taste. Colombia, Mexico, Guatemala and other countries have adopted this method. Coffee beans produced by washing account for almost 70% of the total output of coffee beans.

Sometimes poor treatment of fermentation time will produce fermentation odor and special sour taste; if handled well, it can form the personalized aroma of coffee beans. At this time, the coffee beans can be sent to various places in sacks or in special containers.

The ripe coffee berries look like cherries and are bright red with sweet flesh and contain a pair of seeds, namely coffee beans (Coffee Beans). Coffee varieties can be divided into small-grain, medium-grain and large-grain species, the former contains low caffeine content and strong flavor, while the latter two have high caffeine content but poor flavor. Coffee sold in the world is generally made of small and medium seeds in different proportions, usually 70% of medium seeds, mainly caffeine, and 30% of small seeds, mainly for their aroma. Each coffee variety generally has a few to a dozen variants. Coffee is more resistant to shade and cold, but not resistant to light, drought and disease. Coffee contains nine kinds of nutrients, such as caffeine, protein, crude fat, crude fiber and sucrose. As a beverage, coffee is not only mellow and delicious, slightly bitter and sweet, but also can excite nerves and dispel fatigue. In medicine, caffeine can be used as an anesthetic, stimulant, diuretic and cardiotonic, as well as to help digestion and promote metabolism. The pulp of coffee is rich in sugar and can be used to make sugar and alcohol. Coffee flowers contain essential oils, which can extract high-grade spices.
