Grinding scale of coffee beans in Yunnan introduction of varieties in manor production area by taste treatment method

Small-grain coffee is suitable for growing 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. Small grains of coffee are mostly planted in dry and hot valleys about 1100 meters above sea level, so they are moderately sour, rich and mellow. There is a unique environment suitable for the growth of small seed coffee in many areas of Yunnan, and the quality of small seed coffee is excellent.

The planting areas are mainly distributed in Lincang, Baoshan, Simao, Xishuangbanna, Dehong, Nujiang and other states.

The average temperature of Lujiangba in Baoshan is 21.5℃, and the highest is 40.4 ℃, which is basically frost-free all the year round. It is recognized as the best producing area of small-grain coffee. The small-grain coffee cultivated here is famous at home and abroad for its strong but not bitter, fragrant but not strong, well-proportioned small noodles, mellow and fruity.

In recent years, the planting area of small-grain coffee in other producing areas of Yunnan has been expanding, the quality has also made great progress, and the popularity of small-grain coffee has been improved both at home and abroad.

After inspecting the coffee planting and primary processing base in Yunnan, international coffee organization tasting experts rated Yunnan coffee as the kind of small seed coffee processed by Colombian wet processing, which is the highest quality coffee in the world.

Yunnan can be said to be the only province still growing Arabica on a large scale, mainly in Dehong Lincang, Baoshan, western Yunnan and Pu'er Banna in southern Yunnan. Robusta was the main coffee introduced by missionaries in the 19th century, and then it was no longer planted on a large scale. Experts assisted by the Soviet Union brought two mainstream Arabica varieties, typica and Bourbon bourbon, to Baoshan, Yunnan, for cultivation and promotion, which were well received. Later, due to the special period, scientific research and cultivation tended to stagnate. After the reform and opening up, thanks to the efforts of local agricultural experts, the iron pickup varieties cultivated by Baoshan state-run Lujiang Farm and Xincheng Youth Farm also won the first place in the international coffee competition. However, the Chinese people's understanding of coffee, so that we do not increase too much interest in growing. Since the early 1990s, in order to improve the enthusiasm of farmers, Baoshan Rezuo has introduced a Katim variety bred by the Portuguese Coffee Rust Research Center with Timor (medium grain, Tim) and Caturra (small grain, Kaddura), and has been popularized and planted with numerous titles. This variety has solved many factors such as disease and insect disasters and drought resistance, and the important thing is that the yield per mu has nearly doubled. Although it has increased the enthusiasm of farmers to grow coffee, it has also become the reason for the low quality of Yunnan coffee from now on. At the same time, Nestl é and Maxwell entered China and began to promote coffee varieties suitable for instant coffee in Pu'er and other places: S288, natural hybrid of large seed and small seed and S26 of kent hybrid of Arabica Kent in India, which had first-class rust resistance, but with low planting difficulty and adaptability, it basically stopped planting at the beginning of the 20th century.
