Chinese coffee is concentrated in Yunnan and Hainan provinces. Yunnan has a large output, with an annual output of about 26000 tons in recent years, accounting for 90 per cent of the country's output. It is said that Yunnan coffee came from the French 70 or 80 years ago.

The recent release of Yunnan Coffee as the theme of the film "coming home at one o'clock" has attracted people's attention to Yunnan coffee, and the popularity of Yunnan coffee has risen to another level. So what is the flavor of Yunnan coffee? today, Qianjie will share the details of Yunnan coffee. Why do Yunnan coffee beans pay so much attention to treatment in recent years? In recent years, Yunnan single coffee often appears in the major consumer markets as a special treatment, which undoubtedly changes the public's bad impression of Yunnan coffee in a short period of time. If you are careful, you will find that most of the coffee varieties used in various special treatments are Katim, that is, Yunnan small-grain coffee.

Katim coffee variety Katim is a combination of Arabica and Robusta. Robusta has good resistance to leaf rust and rich oil, high yield and easy to grow. Katim has 25% of the Robusta gene after crossing with Arabica. Katim has 25% of the Robusta gene, which improves resistance to leaf rust and retains rich oil. at the same time, it also has the rich taste of some tin card original species. Nowadays, Katim is widely planted in Yunnan. However, Qianjie is well aware that a coffee that can maintain a stable and good flavor for a long time is often inseparable from the problems of coffee variety, planting environment, agricultural technology and so on. The change in the flavor treatment of coffee directly from the end of agriculture will only cure the symptoms rather than the root causes. So Qianjie went on with our idea of growing fine coffee while baking coffee. At the same time, we also visited the hot science institute (Tropical Agricultural Science Research Institute), which has in-depth research on coffee cultivation and the coffee provenance bank of the Ministry of Agriculture. A small number of farmers who planted fine coffee have found out the reasons why Tibica and Bourbon, the mainstream varieties of fine coffee, are not cultivated in Yunnan, and under the circumstances of coincidence. A piece of land suitable for planting was found on the border between Yunnan and Myanmar, and the road for planting in Yunnan began on Qianjie.

The coffee seedling chosen in front of the street is a tin pickup. This is an ancient coffee variety, its flavor is good, pure blood of the ancient Arabica species also has many weaknesses, such as low yield, weak vitality, poor disease resistance. It is for these reasons that more energy and resources are needed to cultivate iron pickups, which is why Yunnan farmers prefer Katim with high yield and strong vitality. The Ironpika coffee variety has distinct characteristics, and it is probably the easiest to identify. These plants are conical, with main vertical trunks up to 5 meters high. This height means that the distance between branches and nodes on the same branch is longer than that of other varieties. The lateral branches form an angle of 50 to 80 °with the vertical trunk. The trunk and branches are not very strong. Leaves, fruits and raw beans are usually slender, and the bud tips of young leaves are bronze. Ironpickup has a smoother leaf surface and fewer wavy boundaries than other Arabica varieties. The typical iron pickup fruit is bright red when it is ripe.

The bronze color of the top leaf of the iron pickup is one of the characteristics, with large beans, pointed oval or thin pointed shape, and some people call it "red top coffee". Iron pickup coffee has its unique quiet and clean flavor, as well as balanced features, high cleanliness, but the only drawback is insufficient production, altitude requirements, at the same time easy to infection with leaf rust, and resistance to diseases and insect pests is not strong. Coffee cultivation in Yunnan is mainly distributed in Lincang, Baoshan and Pu'er, which has natural resources of low latitude, high altitude (1000-2000m) and large temperature difference between day and night. Yunnan has become a golden growing area for producing Arabica coffee. Pu'er coffee has a history of 100 years. It began to be cultivated at the end of the 19th century and developed into industrialization in 1988. Now the coffee planting area of the whole city has reached 767000 mu. It has become the main coffee producing area and coffee trade distribution center with the largest planting area, the highest yield and the best quality in the mainland.

Lincang: located in the southwest of Yunnan Province, the Tropic of Cancer runs through the south, Pu'er to the east, Dali to the north, Baoshan to the west, and Myanmar to the southwest. It is a bright pearl in the southwest of the motherland because it is bordered by the Lancang River. The annual average temperature in Lincang is between 16.8 ℃ and 17.2℃. The dry and wet season is obvious and the sunshine is sufficient. Baoshan: the average temperature in Baoshan is 21.5℃, the highest is 40.4 ℃, and it 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. Baoshan small-grain coffee in Yunnan has a long history of cultivation. Baoshan small-grain coffee can be said to be a national geographical indication product. The Yunnan coffee growing area of Qianjie Coffee is also sitting here.

The traditional washing method of Yunnan coffee came to the Yunnan producing area of the planting season and really realized what the rainy season is. It is sunny for a few minutes and it rains for half an hour. Because of the perennial rainy season and unstable climate, Yunnan coffee beans on the front street are usually treated with water. Use a peeling machine to separate most of the pulp from the coffee beans, then guide the shelled beans to a clean sink, soak them in water and ferment to completely remove the residual pulp layer. In the past (about five years ago), washing was often the first choice for good coffee bean treatment. Through water treatment, unripe beans and defective beans are selected because of buoyancy, and the fermentation process is easier to control, so the flavor is not mixed like sun beans, but shows obvious acidity, complexity and cleaner (without any negative flavor, such as astringency or sharpness). Qianjie Coffee roasting Analysis Yunnan small Coffee (Katim): Yangjia 800N (roasting capacity 300g): furnace temperature 190 ℃ into the pot, firepower 120, throttle open 3; tempering point 1 temperature 39 ℃, open the throttle to 4, the firepower remains unchanged; when the furnace temperature is 166℃, the bean table turns yellow, the grass flavor disappears completely, and enters the dehydration stage, when the furnace temperature reaches 188℃, the firepower is adjusted to 60 ℃, the throttle is 5. The smell of toast obviously changes to the smell of coffee, which can be defined as a prelude to an explosion. At this time, it is necessary to listen clearly to the sound of the explosion point.
