Description of the flavor of Yunnan small-grain coffee introduction to the characteristics of taste varieties in the producing areas

Coffee production in Yunnan is wet, that is, peeling after picking ripe coffee fruits (generally required within 24 hours after picking), fermentation (depending on the weather, air temperature, and the number of coffee fruits in the same batch, usually 12-24 hours), washing (washing off the sticky substances attached to coffee beans), water washing and grading (beans with different plumpness pass through a trough with a certain slope Coffee shells, shrunken beans and beans with poor plumpness are the first to rush out of the sink. The beans with the best plumpness are at the end. Then, most of the coffee in Yunnan is sold to Nestl é, Maxwell, Starbucks and other enterprises in accordance with the contract, and the coffee bean production standards are currently based on the standards of the above-mentioned enterprises. The moisture content is 11.4%, the price is 12.5%, and the rate of good beans is 98%. The coffee provided by our shop is AA grade coffee, that is to say, it is higher than the standard of the enterprise. After being graded by a large color sorter, the ground coffee beans are graded manually. The amusement rate reached 99.9%. What on earth is AA?

Actually, in terms of taste, I've tried it myself. Class B round Arabica coffee beans taste more mellow. But from a traditional point of view, AA means that coffee beans are big enough. One coffee fruit that produces two beans is a soybean variety. If you can become A, you must be a variety with single fruit and double beans. So if you see that spherical beans are called Grade A, that's nonsense.

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. After visiting the coffee garden of Lujiang Farm, Steyhead, a chief coffee expert of the United Nations Planning and Development Program, said: "I have seen countless coffee plantations in the world. The management here is world-class and the yield per unit area is the highest.
