Why the higher the altitude, the better the coffee beans?-which brand of Vietnamese coffee beans is better?

Generally speaking, with the increase of altitude, the aroma of coffee becomes more and more prominent and unique (see figure). From the temperature and sweetness of Brazilian beans at 3500 feet above sea level to the soaring taste of Ethiopian coffee beans above 6000 feet, it shows that the increase in altitude will make the coffee beans better display the complex and subtle taste.

The influence of geographical location on the flavor of coffee beans is profound. All coffee grows in the tropics, and the altitude at which it grows has a profound effect on the taste of the coffee. From the tropics to 30 degrees north latitude and the mountains south of the equator produce the world's truly high-quality Arabica coffee. Central and South America, South Asia and some Pacific islands, and south-central Africa are also the most important coffee-growing areas in the world.

3000-6000 feet about 1000 meters to 2000 meters above sea level provide ideal conditions for coffee to grow: an average frost-free climate of 60-70 degrees Fahrenheit throughout the year, about 80 inches of moderate rainfall, and abundant sunshine. Coffee beans grow slowly in cold mountain areas, but the slow ripening process makes coffee beans have higher sugar content, more interesting flavor and mellow flavor. At high altitude, the displacement is high, and the fruit taste is more concentrated. The best Arabica coffee-growing areas have very fertile soil, often in volcanic areas.

Coffee beans grown at high elevations are hard, dense and have the potential to give full play to their special flavor. The really amazing coffees are grown between 4000 and 6000 feet above sea level, and these beans are picked carefully only during the mature season.

Secondly, how do we know if the coffee we buy is really high altitude? Coffee growth and reproduction has specific requirements for environmental conditions, sexual preference for calm wind, cool, shaded or semi-shaded environment. In other words, coffee can not be grown and produced in any environment. In other words, coffee production is regional. Most of the coffee producing areas in the world are distributed in tropical plateaus or high-altitude mountain areas. The heat in the equatorial area is high and can be planted to about 2000 meters above sea level; the heat on both sides of the Tropic of Cancer is relatively low, mostly below 1000 meters. In China, it is mainly distributed in Yunnan, bounded by Ailao Mountain, and mainly planted below 900m in the east; in the west, it is mainly planted below 1200 m above sea level, and a few can be planted up to 1500 m above sea level; in the hot area of the Jinsha River basin, it can be planted to 144m 1670m. So to buy high-altitude coffee, you have to ask the origin. If a seller tells you that the producing area is to the east of Ailao Mountain in Yunnan and the elevation is 1200 meters, it is absolutely deceiving you, because coffee cannot be grown at this altitude at all in this area.
