The growth environment and growth process of coffee trees introduce why Chinese people like Starbucks

Coffee beans are fresh and green coffee raw beans, which are obtained by removing red pulp, peel and silver skin from coffee fruit. The structure of coffee fruit is composed of outer skin, pulp, endocarp, silver skin and seeds. The shape is oval, usually the fruit of coffee is composed of two oval seeds opposite each other and the other side is flat, so it is called flat bean, but there is also a round seed called round bean whose taste is no different.

The color of coffee flowers is white, jasmine fragrance, about three to four days to thank, the flowers show five petals, five males and one female. And its cotyledon tip is pointed, the two pieces are relatively grouped, the leaf surface is dark green, the back is light green, oval.

The higher the growth height of coffee beans, the higher the acidity, and the price is higher for coffee with proper sour taste, such as Blue Mountain Coffee, which is naturally balanced in sour, sweet and bitter taste and full of flavor.

Coffee has four flavors and one fragrance: aroma, bitterness, sour, mellow, sweetness and aroma are the life of coffee and the best expression of coffee production process and baking technology. at present, coffee trees are mainly planted in Arabica, Robusta and Liberia. Arabica seed produced in Elaraby Sinia (now refers to Ethiopia) has the highest quality of the three major tree species, accounting for 2/3 of the world's coffee production. Coffee beans are oval and flat, characterized by strong aroma and good quality. Robsta seed is produced in Congo, Africa, strong disease resistance, high temperature resistance, fruit slightly smaller, accounting for 30% of the world output, bitter but not sour, aroma is not very good, most of them are made into mixed coffee. Liberica is native to Liberia in Africa. It has light fragrance and bitter taste, and its quality and yield are all poor. Coffee trees belong to Akanaceae evergreen plants, are tropical plants, and are not cold-tolerant. Most of them are grown in areas with an elevation of 300 ℃ 400 meters, and they are also cultivated on highlands with an elevation of 2000 Mil 2500 meters. However, the quality planted on hillsides above 1500 meters above sea level is better, and coffee trees are most suitable for growing at an average temperature of about 20 meters. With an annual precipitation of 1500 ha 2000 mm, the soil is highly permeable, and in an environment suitable for sunshine, coffee is afraid of Frosts Descent and the cold winter, so it must not be planted in the highlands where frost falls. In general, wild coffee trees can grow to about 8 meters. In order to ensure the quality of coffee beans, easy to manage and harvest, the height is generally cut to 2 meters. Coffee beans begin to bear fruit 3 to 5 years after sowing, and 5 to 20 years is the harvest period. A coffee tree can receive about 3 to 5 kilograms of coffee fruit per year. Coffee comes from coffee beans, and coffee beans are harvested and processed from the fruits of coffee trees.

Coffee trees grow in tropical or subtropical countries called coffee belts, which are centered at the equator and between latitudes 25 degrees south and north. At present, there are more than 60 coffee producing countries. Coffee is produced in South America, Central America, the West Indies, Asia, Africa, Arabia, the South Pacific and Oceania. In terms of production, Brazil ranks first in the world, accounting for about 30%. The second is Colombia-centered Central and South America, accounting for 60%, accounting for about 10%, followed by Africa and Arabia accounting for about 30%. The remaining 10% are distributed in Asia and most islands where coffee gives the public the impression of black, bitter, sleepless and excited drinks. The coffee beans we see in the coffee shop are brown in color, roasted beans and amber in color.
