The relationship between the quality of Yunnan small Coffee brewed in Water and the Variety planting area

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.

1) you can use the kind of water used in household filter drinking fountains or filtered tap water.

2) some coffee beans / coffee powder

The amount of water in a cup of coffee in a siphon pot is 110ml (but it will be reduced by about 1/5 after brewing), and the corresponding coffee powder is about 15g.

If the conditions are right, it is best to choose coffee beans within 10 days from the factory and grind them into coffee powder before brewing coffee.

The fineness of coffee powder can refer to the thickness of "ultra-fine granulated" sugar sold in the market.

3) A set of siphon coffee maker (Hario TCA- 3 is used here), including upper cover, upper seat, lower seat, siphon pot bracket, filter, alcohol lamp (95% industrial alcohol) and alcohol lamp windshield. Because the firepower of the alcohol lamp is difficult to adjust during use, it is necessary to make it smaller (the cotton core only needs to leak 2mm from the top).
