Introduction to the treatment methods of Grinding degree in producing areas for describing the Flavor of Iron skin Coffee in Yunnan, China

Coffee quality is determined by many factors such as the growing environment, climate and cultivation management techniques. Its excellent growth environment is low latitude, high altitude, sufficient rainfall, suitable sunshine, so north latitude 15. The ideal growth zone for coffee is between Tropic of Cancer and Tropic of Cancer. Our company's planting base in Yunnan is located at 23℃ north latitude and 99℃ east longitude. The base altitude is 1230 meters low and 1540 meters high. The altitude difference is 310 meters. The terrain is mainly mountainous and sloping, and the fluctuation is large. The soil is fertile, the sunshine is abundant, the rainfall is abundant, and the temperature difference between day and night is large. These unique natural conditions form the special taste of Yunnan coffee-strong but not bitter, fragrant but not strong, slightly fruity, and the quality is similar to that of Colombia small coffee. Fresh coffee is generally picked from November to February of the following year and processed by washing and wetting. Coffee processing is using advanced imported equipment. Yunnan Coffee currently supplies 30% of its products to the domestic market and 70% to foreign countries.

The fruit is usually large and oval, and the leaves are slender. It is found in Jamaica in Central America and Indonesia in Asia. Likes to grow in fertile mountain soil, cold tolerance and disease resistance is weak, yield is low. The famous Jamaica Blue Mountain Coffee belongs to this variety

The so-called new variety actually refers to catimor (Catimo), which is a hybrid of the Timor species of the Robesta family and Arabica. Compared with the old variety, it lacks rich aroma and taste, and has a relatively shallow grassy smell and earthy taste. However, its advantages lie in its resistance to pests and diseases, easy management, and large yield. Its yield per mu can reach up to 350kg of raw beans, which is more than twice that of the old variety.

Therefore, after Nestle successfully promoted high-yield new varieties in Pu 'er area in the 1990s, coffee farmers in Baoshan area also cut down old varieties and planted new varieties. With the expansion of coffee planting in a round, new varieties increased day by day, and old varieties decreased day by day. Finally, today's situation: old varieties were almost cut down, and the surviving ones were all "old, weak and sick". Most of them were over 20 years old. After a long time, the yield and quality were much lower than before.

Of course, if it is used to make instant coffee or general commercial beans, high-yield catimor is a good choice, but if you want to find Yunnan specialty coffee, then the old variety Tiepi card because of its congenital excellent genes will become the first choice. Therefore, this trip to Yunnan, all the way is also following the old varieties of Fangxing line. But the reality is cruel. Before I went, Brother Zou told me that there was still an old variety in his relative's house. He rushed over excitedly and saw a wild coffee forest. This land belonged to his aunt's house. Because my aunt was too old to change the cultivation and renovation, these old varieties survived. However, my aunt could not manage it alone, so she let the tree grow naturally and picked some fruits when it matured.
