Fragrant Yunnan small Coffee Huaguoshan Fine Coffee Bean Grinding degree treatment method

Yunnan coffee varieties have been judged, right? What about the excellent iron pickups and bourbon? New promotion planting, or left a lot of hills, continue to plant old varieties of coffee, but, popular, backward places do not have the origin and protection of a single species, a mountain, 10 households, all kinds of, a gust of wind blowing, pollen flying everywhere... hehe. The problem of variety makes Yunnan coffee really lose at the starting line.

In addition, the environmental problems of coffee planting, although it can reach the hot zone standard, are far away from the equator, evaporation problems, large-scale Yunnan coffee planting land is less than 1100m above sea level, Yunnan drought in recent years, and frost period problems in the producing areas, etc., all of which make coffee planting unable to be guaranteed normally, directly affecting the quality of the products. As for other processing problems and coffee farmers 'literacy problems, there is not much to say. Tea farmers drink tea for generations, but coffee farmers may not have drunk coffee in their whole lives.

Say so much, but it doesn't mean you haven't drunk a cup of good Yunnan coffee. If the post-processing and baking are good, the coffee from several hills such as Pu 'er Manlaojiang, Manzhongtian Kadura, Baoshan Lujiang Baihualing, Nankang Boben, etc. is still good, especially Nankang, an old variety with an altitude of 1800m.

When the coffee solution in the upper seat is sucked into the lower seat, some foam will form above the liquid level in the lower seat in the final stage. By observing the shape of the foam, you can judge whether the heat and extraction are appropriate: if there is a lot of fine foam, it indicates that the coffee is too hot, and the coffee taste will be quite bitter; if it is a large bubble, and disappears after a few seconds, it indicates that the heat is ideal; if there is almost no foam, it indicates that the heat is insufficient. If you find that the heat is not appropriate, you can adjust it by increasing or decreasing the time of "braising" in the later brewing.

Having said so much, in fact, this is only the basic usage of using siphon pot (there are double flush method, smell method, viscosity method, etc.), as long as you practice more at ordinary times, and constantly correct according to the actual taste, I believe you will be able to cook a cup of coffee that really suits you.

Coffee is rich in protein, fat, sucrose and starch, caffeine and other substances, made of beverage aroma rich, delicious taste, rich nutrition, thus becoming the world's three major drinks and tea, cocoa composition, and ranked first. Yunnan coffee is a variation of Arabic original species, after long-term cultivation and domestication, generally known as Yunnan Arabica coffee, has been cultivated for more than 100 years. Why is it the best quality in the world?

Coffee quality is determined by many factors such as the growing environment, climate and cultivation management techniques. Its best growth environment is low latitude, high altitude, rainfall, sunshine suitable, so north latitude 15. The ideal growth zone for coffee is between Tropic of Cancer and Tropic of Cancer. However, other areas in this zone, such as Hawaii in the United States, Saudi Arabia, etc., or low altitude, or desert with little rain, are not conducive to coffee growth. Only southern Yunnan in this zone has all kinds of conditions. According to experts, Arabica coffee should be planted in the mountains at an altitude of 800~1800 meters. If the altitude is too high, it tastes sour, and if it is too low, it tastes bitter. Yunnan coffee is mostly planted in dry and hot valley areas at an altitude of 1100 meters, so the acidity is moderate, the flavor is rich and mellow. As far as climatic conditions are concerned, the long sunshine time in southern Yunnan is conducive to the growth and photosynthesis of plants, and the large temperature difference between day and night and the low temperature at night are conducive to the accumulation of coffee nutrients. Therefore, the effective nutrients contained in Yunnan Arabica coffee are higher than those of other coffee varieties abroad. Arabica coffee is susceptible to rust, and its yield and quality are greatly affected after rust. Yunnan hot zone due to dry and wet distinct, every year fresh fruit red ripening just into the dry season, low relative humidity, is not conducive to the formation and growth of blister rust. Because of the excellent quality of Yunnan coffee, it entered the London market in the 1960s as "Lujiang No.1" and was rated as a first-class product. In recent years, world-famous coffee companies such as Nestle and Mai's have come to Yunnan to open up raw material bases, and Yunnan's products have gradually gained popularity at home and abroad. At present, the average yield of coffee in Yunnan Province has reached 96.4 kg, and a family contracted land in Lujiang has set a world record of 400 kg. "I've seen countless coffee plantations in the world," said Steisos, a chief coffee expert at the United Nations Development Programme, after visiting the Lujiang farm."The management here is world-class and the yield is the highest."

1. Sexual reproduction

Sexual reproduction is a method of reproduction that can obtain a large number of seedlings at one time. First, it is seed selection and seed treatment. Improved varieties are the basis for cultivating strong seedlings and improving yield. It is necessary to carefully select improved varieties. On the coffee mother tree, select completely mature, fruit shape normal, full and consistent, with two seeds. Remove the peel of the selected fruit, the operation must be careful to prevent damage to the seeds and affect the germination rate, and then put the peeled seeds in a ventilated and cool place to dry, the seeds can be stored after the shell turns white, do not expose the seeds, put the seeds into bamboo baskets or cloth bags, turn over the sun once a month, so that the long-stored seeds maintain a high germination rate. After the seedling bed is arranged, it can be sown. According to the sowing of 1 kg of seeds, it takes 1.5 square meters of seedbed, each kg of seeds is about 3500--4000, the emergence rate is above 80%, and the seedlings can be transferred to 2500--3000. Before sowing, it can be soaked in warm water at 40℃ for 12 hours to germinate, and the effect is best. 50--80 days after sowing seedlings can emerge, when seedlings appear two leaves can be transplanted to the nutrition bag management, seedling when the seedbed drench water, roots as much as possible with some soil, pay attention not to damage roots and stems. After planting, irrigate enough fixed root water and shade with small shade. Seedling seedlings easy to dry death, should be timely supplement water, drenching 1- 2 times a day, rainy days can be less. When the seedlings grow to 2- 3 true leaves, apply water and fertilizer for the first time. Apply 1000kg of human excrement and 5kg of calcium superphosphate per mu and add 2000kg of water. Later, apply water and fertilizer once when 4- 5 pairs of true leaves and 7- 8 pairs of true leaves respectively. Stop applying fertilizer 1- 2 months before seedling emergence to stabilize seedlings and facilitate survival after planting.
