Coffee is rich in protein, fat, sucrose, starch, caffeine and other substances. After being made into a beverage, it has rich aroma, delicious taste and rich nutrition. Together with tea and cocoa, it has become the three largest beverages in the world and ranks first. Yunnan coffee is a variety of Arabic original species, which has been cultivated and domesticated for a long time. Generally known as Yunnan small seed coffee, its cultivation history is over 100 years. Why is it the best quality in the world?
The quality of coffee depends on many factors, such as growing environment, climate, cultivation and management techniques, etc. Its best growing environment is low latitude, high altitude, abundant rainfall and suitable sunshine, so the north latitude 15. Between the Tropic of Cancer and the Tropic of Cancer, it is an ideal growing area for coffee. However, other areas in this area, such as Hawaii and Saudi Arabia, etc. Or low altitude or little rain in the desert are not conducive to coffee growth. Only southern Yunnan, which is located in this area, has all kinds of conditions. According to experts' determination, small coffee should be planted in mountainous areas with an altitude of 800~ 1800 meters. Too high an altitude will be sour, too low will be bitter. Yunnan coffee is mostly planted in the dry-hot valley at an altitude of 1 100 meters, so it has moderate acidity, rich flavor and mellow taste. As far as climatic conditions are concerned, the long light time in southern Yunnan is beneficial to the growth and photosynthesis of plants, the large temperature difference between day and night and the low temperature at night are beneficial to the accumulation of nutrients in coffee, so the effective nutrients in Yunnan small coffee are higher than those in other foreign coffee varieties. Small coffee is easy to be infected with rust, and the yield and quality after embroidery are deeply affected. Due to the distinct dry and wet conditions in the hot areas of Yunnan, red ripe fresh fruit just enters the dry season every year, and the relative humidity is low, which is not conducive to the formation and growth of rust blisters. Due to the excellent quality of Yunnan coffee, it entered the London market as "Lujiang No.1" in the 1960s and was rated as a first-class product. In recent years, world-renowned coffee companies such as Nestle and Macmillan have opened up raw material bases in Yunnan, and the products produced in Yunnan have gradually gained a good reputation at home and abroad. At present, the average yield of coffee per mu in Yunnan Province has reached 96.4 kilograms, and a contracted land in Lujiang has set a world record of 400 kilograms. Stacey, the chief coffee expert of the United Nations Development Programme, said after visiting the coffee garden of Lujiang Farm: "I have seen countless coffee gardens in the world, where the management is world-class and the output is the highest.
