How Did Yunnan Coffee Become a Coffee Origin?

Yunnan is China's main coffee-producing region, leading the country in both planting area and output. Cultivation there traces back to 1892, and the crop grown today is mainly Catimor, the variety commonly called Yunnan small-bean coffee. Starbucks' Phoenix Dancing Auspicious Clouds beans, launched in 2009, were the first blend to include Chinese Yunnan small-bean coffee, which brought the origin wider attention.

Yunnan arabica is graded by screen aperture size, and its main growing areas include Lincang, Baoshan, Pu'er, and Dehong. Varieties such as Typica, Bourbon, and Catimor each contribute different cup characteristics, while washed, natural, and specialty processing methods shift the flavor further. A medium roast and careful pour-over parameters bring out the region's signature profile: strong but not bitter, fragrant but not harsh, with a slight fruity note.

Yunnan, as China's core coffee-producing region, dominates the country in both planting area and output. This article starts with the packaging symbolism of Starbucks' Phoenix Dancing Auspicious Clouds coffee beans, traces the cultivation history of Yunnan coffee since 1892, explains in detail the characteristics of varieties such as Typica, Bourbon, and Catimor, and introduces the grading system based on screen aperture size as well as the terroir of major producing areas including Lincang, Baoshan, Pu'er, and Dehong.

Characteristics of Yunnan coffee beans and story introduction

Asia is universally recognized as one of the three major coffee-producing regions in the world, and its output and quality are by no means inferior to the other two. When it comes to Asian coffee, coffee beans produced in Yunnan, China, are an unavoidable topic. Front Street Coffee once systematically analyzed Yunnan coffee in another article. At present, the coffee grown in Yunnan is mainly the Catimor variety, which is what everyone commonly calls Yunnan small-bean coffee. The Phoenix Dancing Auspicious Clouds coffee beans launched by Starbucks in 2009 were the first blend to incorporate Chinese Yunnan small-bean coffee beans. Front Street Coffee has always believed that coffee quality is affected by many factors, and variety is the most critical link among them. Any discussion of flavor that detaches itself from coffee variety actually lacks a basis to stand on.

The story of Starbucks Yunnan coffee beans:

The packaging of Starbucks' Phoenix Dancing Auspicious Clouds coffee beans is quite meaningful: the design outlines a phoenix, set against high mountains and deep valleys. In the traditional Chinese symbolic system, the phoenix is the embodiment of perfectionism. According to research, the phoenix is regarded as a divine creature of "harmony," carrying the ancients' understanding, respect, and awe of all things in nature, and also symbolizing virtue and prosperity.

The cultivation history of Yunnan coffee can be traced back to 1892. At that time, a French missionary brought coffee seeds into Yunnan from abroad and planted the first coffee tree successfully on the land of Zhukula. He probably never expected that a century later, coffee would become a calling card of Yunnan's plateau characteristic agriculture.

Around 1930, the famous overseas Chinese leader Mr. Liang Jinshan introduced coffee to the Pupiao and Luoming areas, and this line continued until the founding of New China. After 1952, under the guidance of expert Ma Guojin from the Baoshan Tropical Economic Institute, large-scale coffee planting began in Lujiang and other places, and the history of large-scale cultivation has now lasted nearly sixty years.

In the mid-1990s, the planting scale once reached 4,000 hectares. By the end of 1997, the province's coffee planting area had climbed to 7,800 hectares. Today, Yunnan's planting area accounts for 70% of the country's total, and its output accounts for 83%. Whether measured by area or output, Yunnan coffee has firmly established its dominant position in China.

Yunnan coffee varieties

Typica and Bourbon, two classic high-quality varieties, were once the main cultivated targets of Yunnan coffee. In 1991, the Catimor series was introduced from Kenya (with stronger disease resistance and higher yield), belonging to a variant of the Arabica species (also called small-bean species). Because these two varieties are similar in morphology and habits, they are mostly cultivated in mixed planting.

[Catimor coffee (small-bean coffee)]

In 1959, the Portuguese moved Caturra, a mutant of Brazilian Bourbon, to East Timor, and crossed it with Timor, which carries Robusta lineage, successfully breeding Catimor with extremely strong disease resistance and productivity. Afterward, leaf rust swept through coffee-producing countries around the world. With the assistance of international organizations, producing countries vigorously promoted Catimor to resist leaf rust and increase productivity.

Yunnan small-bean coffee begins to bear fruit 3 to 4 years after planting. Coffee is a short-day plant and has the characteristic of flowering multiple times with a concentrated flowering period. The flowering period of small-bean coffee in Yunnan is from February to July, with the full blooming period from March to May. Flowering is greatly affected by climate, especially rainfall and temperature. Coffee flowers have a very short lifespan, only 2 to 3 days. Small-bean coffee usually begins to open at 3 to 5 a.m. and blooms fully from 5 to 7 a.m. The development cycle of coffee fruit is relatively long. For small-bean coffee, it takes 8 to 10 months from fruit set to maturity, generally maturing from October to December of the same year. Rainfall has a significant impact on fruit development, and climatic conditions directly influence fruit growth.

[Typica coffee]

Typica is the oldest native variety in Ethiopia, and all Arabica varieties are derived from Typica. Typica has bronze-colored young leaves, and the beans are oval or slender-pointed; the flavor is elegant, but the plant is relatively weak, has poor disease resistance, and produces few fruits. At Front Street Coffee's plantation in Yunnan, mainly Typica and a small amount of Bourbon are planted.

Yunnan small-bean coffee was originally named because of Typica, since Typica is precisely the Arabica small-bean species. But times have changed. The Typica variety has degraded and has low yield, and has gradually been replaced by Catimor. Surprisingly, the name "small-bean coffee" was inherited by Catimor. Front Street Coffee sees no contradiction between Catimor and Typica: one is a raw material, and the other is specialty coffee. The significance of specialty coffee lies in improving quality, while the significance of raw materials lies in increasing yield. It is also a reasonable choice for Yunnan to be dominated by Catimor. Looking across the history of coffee development, it is inherently a process of gradual transition from commercial coffee to specialty coffee. Front Street Coffee believes that Yunnan's coffee road still has a long way to go.

Yunnan coffee bean grading system

Grading is based on coffee bean size and uses round-hole grading screens. The internationally customary size grades for small-bean coffee range from 10 to 20. The number used represents the screen aperture, with that number as the numerator and 64 as the denominator, in inches. For example: 14 indicates green coffee beans that can pass through a screen with an aperture of 14/64 inch or above, while 19 indicates green coffee beans that can pass through a screen with an aperture of 19/64 inch or above. (1 inch ≈ 2.54 cm)

Common domestic coffee grading standards:

Divided into five grades according to screen apertures of 6.5, 6.0, 5.5, and 5.0 mm.

Grade 1: above 6.5 mm, plump and intact beans.

Grade 2: 6.0-6.4 mm, plump, relatively uniform.

Grade 3: 5.3-5.9 mm, relatively plump, slightly less uniform.

Grade 4: 5.0-5.4 mm, contains incomplete beans, with intact beans accounting for more than 75%.

Grade 5: below 5.0 mm, contains incomplete beans, with intact beans accounting for more than 30%.

Detailed international standards for inspecting defects in small-bean coffee:

Grading is carried out according to the amount of defective material contained, often determined by how many defects are present in a certain amount of coffee beans. According to the identification methods for impurities and defective beans in coffee beans stipulated by the International Organization for Standardization, a 300-gram coffee bean sample is randomly selected, and the impurities and defective beans in it are counted for grading.

Yunnan coffee-producing areas

Western and southern Yunnan lie between 15°N and the Tropic of Cancer. Most areas are 1,000-2,000 meters above sea level. The terrain is mainly mountainous and sloped, with considerable undulation, fertile soil, abundant sunshine, rich rainfall, and large temperature differences between day and night. These unique natural conditions have shaped the particular taste of Yunnan small-bean coffee—strong but not bitter, fragrant but not harsh, with a slight fruity note. Coffee cultivation in Yunnan is mainly distributed in Lincang, Baoshan, Pu'er, and Dehong.

[Dehong Prefecture] The birthplace of Chinese coffee. This area has an altitude of 1,000 to 1,600 meters and a coffee plantation area of 2,000 hectares. More importantly, most coffee is organically grown here.

[Pu'er] The coffee capital. In 2012, Pu'er's planting area was 43,433 hectares, the coffee harvest area was 18,000 hectares, and the annual coffee output was 36,500 tons, of which 24,700 tons were exported. Pu'er's coffee industry has 70 registered enterprises, 30,000 households, and about 1 million people.

[Baoshan] Small-bean coffee is Baoshan's most famous coffee. This coffee took its first step in the late 1950s and quickly received positive feedback from London. At the national coffee conference in 1980, it was recognized as the "crown of national coffee." In December 2010, Baoshan small-bean coffee obtained A-level certification and passed the procedures of China's National Standardization Administration, and is considered a product reflecting China's national geographical indication.

Coffee bean processing methods

At present, the processing methods used for Yunnan coffee beans include not only the most common washed and natural methods, but also special processing methods that have now been developed. Front Street Coffee has observed the development trend of the coffee market in recent years, with more effort being put into processing methods. Of course, this itself is a trend determined by the broader environment, and there is no saying whether it is good or bad. Front Street Coffee believes that the premise for changing processing methods is to ensure the recognizability of the producing area's most basic flavor. Overemphasizing flavors detached from coffee itself can actually only appear in the short term and is not lasting. For example, a barrel-fermented coffee bean that Front Street Coffee currently sells very well is indeed stunning in flavor presentation, but its flavor retention is not as lasting as that of natural or washed coffee beans.

Washed processing: Coffee farmers use a depulper to separate most of the pulp from the coffee beans of the harvested cherries, then guide the parchment beans into a clean water tank and soak them in water for fermentation to completely remove the mucilage, and finally dry them to a moisture content of about 12%. Through washed processing, coffee shows obvious fruity acidity and a cleaner mouthfeel.

Natural processing: Compared with washed processing, natural processing is much simpler. Ripe selected coffee cherries are spread evenly on open ground or drying beds (now mostly drying beds, which can avoid picking up off-flavors), dried to a moisture content of about 12%, and then depulped and demucilaged. Natural processing highlights sweetness and fermented notes.

Roasting recommendations

Front Street Coffee chooses medium roasting to showcase the balance, nutty notes, brown sugar sweetness, and soft fruity acidity of Yunnan small-bean coffee. Front Street Coffee's roasting goal is to reflect the flavor of the coffee-producing area. In fact, each coffee bean can be roasted in any way, but Front Street Coffee believes that the roasted taste must be able to reflect the taste of that producing area. For example, Catimor should have the taste of Catimor, and then other possibilities can be developed on that basis. This is Front Street Coffee's only standard for determining coffee roasting.

Pour-over recommendations

For every customer who buys beans, Front Street Coffee emphasizes one point: the beans must be rested before drinking, generally for about 3 days, so that the flavor of the coffee beans can be presented more completely.

Front Street Coffee's brewing parameters can be referenced as follows: Kono dripper, 88°C water temperature, 15g coffee grounds, 1:15 coffee-to-water ratio, grind size: BG#6F (80% passing through China standard No. 20 sieve)

Front Street Coffee chooses a lower water temperature. Normally, when brewing light-roasted coffee beans, a water temperature of 90°C is used. This temperature was set for two reasons: first, coffee beans with a higher roast degree are likely to extract off-flavors at high temperatures; second, after combining SCA brewing recommendation ranges and repeatedly testing parameters, Front Street Coffee finally determined this suitable water temperature, which can ensure that the concentration of extracted substances falls within the golden cup range. The reason Front Street Coffee chooses the Kono dripper is that it has few ribs and they are located at the lower end. The filter paper fits closely against the dripper, which can restrict airflow, lengthen the contact time between water and coffee grounds, allow the coffee grounds to be fully extracted, and enhance the mellow mouthfeel.

The grind size for each coffee bean will be different because of factors such as variety, altitude, processing method, and roasting. Therefore, when Front Street Coffee receives a new batch of roasted beans, it will first sift them once to determine the appropriate pour-over grind.

For the brewing technique, Front Street Coffee recommends segmented extraction, that is, three-stage extraction. Use 30 grams of water for a 30-second bloom. Pour in a small stream in circles until 125 grams, then pause for a segment. When the water level drops and is about to expose the coffee bed, continue pouring until 225 grams and stop. When the water level drops and is about to expose the coffee bed again, remove the dripper. (Start timing at the beginning of the bloom.) The extraction time is 2 minutes.

[Small-bean coffee brewing flavor] It smells strongly of nuts. On the palate there are herbal notes, chocolate, and caramel, with a faint fruity acidity in the aftertaste.
