Basic knowledge of fine coffee the growth environment of small-grain coffee

Small grains of coffee

Scientific name: Coffea arabica

Family and genus: coffee genus of Rubiaceae

Morphological features: small trees or large shrubs, plant height 5-8 meters. Base usually much branched, old branches gray-white. Nodes inflated, young branches glabrous. Leaves thinly leathery-ovate-lanceolate or lanceolate, apex long acuminate, base cuneate or slightly obtuse, entire or shallowly wavy, both surfaces glabrous. Cymes several clustered in leaf axils, Corolla white, fragrant. When ripe, berries are broadly oval, red, 1.2 × 1.6 cm long, and seeds 0.8-1.0 cm long. The florescence is from March to April.

Origin and distribution: originated in Ethiopia or Arabian Peninsula. It is cultivated in Fujian, Taiwan, Guangdong, Hainan, Guangxi, Sichuan, Guizhou and Yunnan.

The growing environment of small-grain coffee

Due to the unique geographical environment and climatic conditions, Yunnan coffee has formed a unique flavor of strong but not bitter, fragrant but not strong, with a little fruit flavor. World-class coffee experts evaluate it as the best coffee in the world, and its cultivation techniques. The yield per unit area is also world-class.

Coffee is rich in protein, fat, sucrose, starch, caffeine and other substances. after being made into a beverage, coffee is rich in aroma, delicious taste and rich nutrition, so it has become the world's three major beverages composed of tea and cocoa, and ranks first in the list. Yunnan coffee is a variant of Arabian original species, which has been cultivated for more than one hundred years after long-term cultivation and domestication. 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 and so on. Its best growing environment is low latitude, high altitude, sufficient rainfall and suitable sunshine, so the north latitude is 15. The ideal growing area for coffee is between the Tropic of Cancer and the Tropic of Cancer. However, other areas in this zone, such as Hawaii and Saudi Arabia in the United States, or low altitude or little rain in the desert, are not conducive to coffee growth, only southern Yunnan in this zone happens to have all kinds of conditions. According to the determination of experts, small seed coffee should be planted in the mountains at an altitude of 800 to 1800 meters. If the altitude is too high, it will taste sour, and if it is too low, it will taste bitter. Yunnan coffee is mostly planted in dry and hot valleys at an altitude of 1100 meters above sea level, so it has a moderate sour taste, rich and mellow aroma. In terms of climatic conditions, the long light time in southern Yunnan is conducive to plant growth and photosynthesis, and the large temperature difference between day and night and low temperature at night are conducive to the accumulation of coffee nutrients. Therefore, the effective nutrients of Yunnan small-grain coffee are higher than those of other foreign coffee varieties. Small seed coffee is easy to be infected with rust, and the yield and quality of embroidery disease are deeply affected. In the hot area of Yunnan, due to the distinct dry and wet, the red ripening of fresh fruit enters the dry season every year, and the relative humidity is low, which is not conducive to the formation and growth of rust blister. Due to the excellent quality of Yunnan coffee, it entered the London market with "Lujiang No.1" in the 1960s and was rated as first-class. In recent years, the world-famous coffee companies such as Nestle and McDonnell have come to Yunnan to open up raw material bases, and the products produced in Yunnan are also gradually famous at home and abroad. At present, the average yield of coffee in Yunnan has reached 96.4 kg, and a household contracted land in Lujiang has set a world record of 400 kg. "I have seen countless coffee plantations in the world, where the management is world-class and the yield is the highest," said Steyhead, a chief coffee expert at the United Nations Planning and Development Program, after visiting the coffee garden at Lujiang Farm.
