Now mention Yunnan coffee beans, I believe everyone is no stranger ~ In recent years, more and more games can see Yunnan coffee beans figure, we no longer stay in the Yunnan coffee beans instant coffee period, more is a branch full of poetic names and coffee beans with charming flavor.

Yunnan Coffee Road

Yunnan coffee originated in 1904, by the French missionary Tian Deneng introduced the first coffee tree in Dali on the Sino-Vietnamese border, and the number of coffee trees planted at that time was not much, we only know that he is called Arabica coffee tree (Arabica variety), and did not carry out large-scale cultivation and planting. In 1930, an overseas Chinese brought coffee trees to other parts of Yunnan to start planting in batches, but everyone was very unfamiliar with this plant, no one drank coffee locally, and they needed careful care. Naturally, no one wanted to cultivate them, so this batch of coffee trees was once again "put aside".

After the founding of New China, China joined the Communist camp. Under the guidance of experts, Yunnan began to plant coffee trees in batches and transported the coffee beans produced to the Soviet Union. At that time, the coffee planting scale in Yunnan reached 4000 hectares. In 1990, Nestle started Yunnan coffee cultivation. In order to increase production, it began to introduce Catim coffee varieties from Brazil. By 1997, the planting area of Yunnan reached 7800 hectares.

Although Katim has a high yield, if the traditional sun/washing treatment method is used, if the coffee is directly brewed, the flavor of the coffee will always be unsatisfactory…So everyone will naturally equate Yunnan coffee with instant raw materials, and label the flavor label of "bad taste". Until recent years, the fine coffee industry has continued to develop, and the processing method of coffee beans has become more and more novel. Through various innovative ways to process coffee beans, the flavor quality of coffee has been improved. Yunnan coffee also valued this point, using special processing methods to cover up the lack of coffee flavor, and then everyone drank it and said yes! So Yunnan coffee beans began to be active in the fine coffee market.

Although the Yunnan katim flavor of special treatment method is very good, if it develops for a long time, everyone will be very unfamiliar with the taste of Yunnan coffee. Qianjie thinks that if you want Yunnan coffee beans to become delicious, you should start from the root. Therefore, since 2013, Qianjie Coffee has planted iron pickup coffee trees in Lincang, which is also the coffee variety brought by missionaries in those years.

The reason for choosing the iron pickup variety is that it is one of the oldest coffee varieties, and the Arabica varieties we see later are all derived from this variety. The variety itself has a clean coffee flavor, although the yield is not as high as katim, and the cultivation is difficult, but the delicate acid has been balanced flavor can always make people aftertaste. Yunnan Tiekka coffee beans grown in Qianjie have delicate acidity, licorice sweetness, slightly lower body and overall balance.

Katim, on the other hand, is a combination of Arabica and Robusta and has 25% Robusta genes, so the coffee flavor is not as clean as the pure Arabica variety. However, as people pay more and more attention to the treatment of coffee beans, the equipment of sunning equipment/washing fermentation tank has been upgraded. Now Yunnan Katim under traditional treatment method can also show good coffee flavor. Qianjie feels Yunnan Katim has nut, brown sugar and plum flavor through cup test, and the overall balance is relatively balanced.

Yunnan coffee bean classification system

Coffee cultivation in China started late, and grain size + defect rate is generally used to grade coffee. The particle size is based on the international standard mesh number (mesh size is 6.5mm, 6.0mm, 5.5mm, 5.0mm)

Grade I: 6.5mm or more, full of particles.

Grade II: 6.0-6.4mm, plump and uniform.

Grade III: 5.3-5.9mm, plump, slightly uneven.

Grade 4: 5.0-5.4mm, incomplete meters, complete accounting for more than 75%. Level 5: below 5.0mm, incomplete meters, complete accounting for more than 30%.

At the same time refer to the international standard of defective bean number, bean shape color, clarity, smell, moisture content and other factors. In recent years, relevant departments of Yunnan Coffee Provincial Government and Pu 'er and other local government departments have vigorously promoted the cultivation and treatment of Yunnan fine coffee, introduced advanced cultivation and treatment methods, held various coffee competitions and other activities, especially the promotion of coffee cup test and coffee quality. It is believed that in the near future, the classification of Yunnan coffee beans will be more rigorous and scientific, and gradually enter the international fine coffee market.

How does Yunnan coffee taste better?

Qianjie will brew two coffee beans this time, one is washed Yunnan iron card coffee beans, one is sun treated Yunnan iron card coffee beans. When brewing, use 15 grams of coffee powder, the grinding degree is medium fine (about 78% of the Chinese standard No.20 sieve), the proportion of brewing powder water is recommended to be 1:15, and the flavor can be 1:16.

Next, the front street will be brewed with v60 filter cups, 88 degrees Celsius water temperature and three stages of water injection, in order to soften the acid. Add 30 grams of water and steam for 30 seconds. Then small water flow circle water injection to 125 grams, when the water level is about to expose the powder bed continue to water injection to 225 grams stop water injection, when the water level is about to expose the powder bed remove the filter cup,(steam-start timing) extraction time is 2 10".
