What Sets Yunnan Coffee Varieties Apart?

Yunnan coffee is China's most recognized producing region, and its beans are mostly Catimor, a Timor and Caturra cross bred for disease resistance and high yield. Typica, an older Arabica variety, is grown on a smaller scale and tends to cup cleaner and sweeter. The two differ clearly in plant shape, yield, and flavor, which shapes how each is farmed and roasted.

Catimor currently dominates Yunnan plantings, while Typica has been cultivated at estates in Lincang since 2013. Yunnan Arabica coffee originally referred to pure Arabica types before Catimor spread. Growers at higher elevations often see better flavor, though yields drop. Washed lots of both varieties show that Yunnan coffee is still moving toward, but has not fully reached, specialty coffee standards.

Yunnan, as China's most renowned coffee-producing region, has developed rapidly in the specialty coffee sector in recent years. Front Street Coffee has been deeply involved in Lincang, Yunnan since 2013, establishing a coffee estate and cultivating the Typica variety, witnessing the entire process of Yunnan coffee's evolution from being dominated by Catimor to continuously improving quality. This article will systematically review the variety composition, growing conditions, and flavor characteristics of Yunnan coffee, compare the respective features of Catimor and Typica, and share Front Street's practical experience in cupping and brewing Yunnan coffee, giving you a comprehensive understanding of the true character and future potential of Yunnan coffee.

Yunnan coffee has been gaining increasing attention both domestically and internationally in recent years. The areas in China where Arabica coffee can be grown are inherently limited, and regions that have developed an industrial scale of coffee cultivation are even fewer—Yunnan is the most representative among them. Some friends may not be aware that Front Street Coffee began investing in coffee cultivation in Yunnan as early as 2013. Over these years, the quality of Yunnan coffee beans has steadily improved, and more and more specialty coffee shops are willing to include Yunnan beans on their menus, which sufficiently demonstrates that Yunnan coffee is heading in a positive direction.

However, as a company that has long been rooted in the Yunnan producing region, Front Street also has firsthand experience of Yunnan coffee's current shortcomings. Overall, Yunnan coffee is in the process of advancing toward specialty coffee, but strictly speaking, it has not yet fully met all the standards of specialty coffee. Therefore, colleagues dedicated to promoting the progress of the Yunnan coffee industry still have a long way to go!!!

The most widely planted variety in Yunnan coffee today is Catimor, which is a cross between Timor and Caturra, giving it the advantages of strong disease resistance and high yield, securing its place among Central American coffee varieties. Among the Yunnan coffee beans offered by Front Street, one Yunnan Arabica coffee belongs to the Catimor variety. It should be noted that Yunnan Arabica coffee originally referred to pure Arabica varieties. Arabica coffee originated in Ethiopia or the Arabian Peninsula. The main growing areas are distributed across Lincang, Baoshan, Simao, Xishuangbanna, Dehong, and other places.

Catimor grows vigorously in Yunnan with stable secondary traits. The tender leaves at the top of the canopy are emerald green, while the entire plant's leaves are dark green. The plant has a columnar shape with short internodes, many branches, wide adaptability, outstanding drought resistance, and a certain degree of cold tolerance. Compared with Typica, Yunnan Catimor's yield is much higher. In fact, according to Front Street's understanding, the first variety planted on a large scale in Yunnan was not Catimor, but Typica, which has excellent appearance and quite good sweetness. Later, as major international brands entered Yunnan and purchased coffee beans in large quantities, Catimor was vigorously promoted for cultivation in order to maximize local yields. Typica, however, due to its low yield and susceptibility to coffee leaf rust, was difficult to manage and offered unsatisfactory economic returns, leading to low willingness among Yunnan coffee farmers to plant Typica.

Although Catimor performs excellently in terms of adaptability in Yunnan, its flavor has always been the focus of discussion. Han Huaizong, in his writings, often uses "the devil's aftertaste" to describe Catimor's flavor. However, Front Street believes that there are numerous variables affecting coffee flavor and one should not make sweeping generalizations. For example, the variety used in Indonesian Mandheling coffee is Catimor, yet Mandheling's flavor is still widely recognized.

Although Typica's planting area in Yunnan is not large, Typica coffee's flavor performance is quite outstanding. One of Front Street's Yunnan coffee beans—Huaguoshan Coffee—is of the Typica variety, and its flavor after brewing is equally satisfying. Yunnan has high temperatures and abundant rain year-round. Local coffee farmers make full use of this natural advantage by using the washed processing method to process coffee beans: first, the harvested coffee cherries are depulped using a depulping machine to remove the skin and pulp, then the processed beans are introduced into clean water tanks and soaked for about 18 hours, using fermentation to remove residual mucilage, followed by drying.

We also conducted cupping and brewing experiments on Front Street. Yunnan Arabica Coffee. The flavor characteristics of Yunnan coffee beans are generally on the balanced side, with a base tone dominated by nuts and brown sugar. In order to highlight the flavor of the Yunnan coffee variety, Front Street used a medium roast for this bean.

Through tasting, Front Street has reached the following conclusions regarding the flavor characteristics of these two Yunnan coffee beans: Front Street 2013 Typica Coffee Bean Cupping Results: Rich melon and fruit aromas on entry, herbal aromas, smooth on the palate, nuts in the mid-palate, chocolate flavors, lively and bright plum acidity in the finish, with black tea and brown sugar notes in the aftertaste.

Front Street Yunnan Arabica Coffee Bean Cupping Results: Bright acidity, soft acidity, good body and balance, rich layers, with obvious black chocolate, honey, and sucrose notes in the aftertaste, and brown sugar flavor when completely cooled.

You can also see from Front Street's Yunnan coffee flavor cupping results that Yunnan coffee's characteristic is not a producing region with acidity as its main tone; instead, Yunnan coffee beans all have relatively balanced flavors with a base tone dominated by nuts and brown sugar. If you want to more clearly experience Yunnan's basic terroir, you can start with Front Street's daily drinking bean series. The formation of Yunnan coffee's flavor is inseparable from Yunnan's special geographical location. Yunnan's natural conditions are very similar to those of Colombia—both are at low latitudes, high altitudes, and with large temperature differences between day and night.

From Front Street's cupping results for Yunnan coffee mentioned earlier, the taste is also very good. Take Front Street. Yunnan Arabica Coffee for example—this Yunnan coffee is somewhat similar to Colombian coffee in flavor, but not entirely the same. Front Street. Yunnan Arabica Coffee has a dry aroma of nuts when smelled, but when drunk, it offers more chocolate, nut, and cream flavors. However, it lacks the caramel sweetness of Colombian coffee and instead has more of a brown sugar sweetness. The overall taste is relatively balanced.

Thanks to Yunnan's superior climate conditions, Yunnan coffee saplings generally take four years from initial planting to bearing fruit and harvest. Front Street has learned that coffee flowers generally have a short lifespan of only two to three days. The peak flowering period for Yunnan Arabica coffee is generally from March to May, and is greatly influenced by rainfall and temperature. Planting altitude is a fundamental factor for coffee cultivation. Large areas of mountainous terrain in Yunnan can reach above 1,000 meters. Kunming has an altitude of 1,895 meters, Baoshan 1,653.5 meters, Dali 1,976 meters, Chuxiong 1,773 meters, Dehong an average altitude of 800 to 1,500 meters, and Diqing an average altitude of 3,380 meters.

With high altitude comes temperature considerations. Generally speaking, the Coffee Belt lies between the Tropic of Cancer and the Tropic of Capricorn, because once outside this belt, the probability of frost is very high, and coffee trees die upon exposure to frost. In Yunnan, because the Gaoligong Mountains lie to the north of Baoshan, they block the Siberian cold currents that sweep southward in winter, and the numerous mountainous areas form protective microclimates for coffee growth.

At its founding, in order to comprehensively understand and share coffee knowledge, Front Street Coffee even established a coffee estate in Lincang, Yunnan. That is, as early as 2013, the most original Arabica variety—Typica—was already being planted at Front Street Coffee Estate. Lincang's average temperature is around 21 degrees Celsius, with maximum temperatures reaching over 40 degrees, making it an ideal location for growing Yunnan Arabica coffee. The Yunnan Arabica coffee produced in Lincang is rich but not bitter, with a mellow and aromatic character.

The year 2022 has arrived, Yunnan coffee's harvest has temporarily come to an end, and the latest batch of coffee beans from Front Street Coffee Estate has also been listed.

Front Street. 2013 Yunnan Natural Typica

Producing Region: Lincang, Yunnan

Estate: Yunnan Front Street Coffee Estate

Altitude: 1,300 meters

Variety: Typica

Processing Method: Natural Typica

The Typica produced at Front Street Coffee Estate uses the most original and traditional green coffee post-processing method—the natural processing method. After natural processing, Front Street's Typica coffee has a fuller body, more prominent sweet and sour notes, with citrus and berry tones, a hint of fermented wine aroma, caramel sweetness, and a creamy aftertaste.

Finally, let Front Street share the parameters used when brewing Front Street's Yunnan Natural Typica:

Dripper: Hario V60

Water Temperature: 90 degrees Celsius

Dose: 15 grams

Coffee-to-Water Ratio: 1:15

Grind Size: 80% passing through a Chinese standard No. 20 sieve

First pour 30 grams of hot water and bloom for 30 seconds, then pour from the center with a fine stream in slow circles up to 125 grams for the first stage. Wait until the water level in the dripper drops to the point where the coffee bed is about to be exposed, then continue pouring in circles up to 225 grams. Total extraction time is approximately 2 minutes.

When Front Street ships, the coffee beans delivered to everyone are freshly roasted within 5 days. By the time you receive them, they have already gone through a 4-to-7-day resting period, and their flavor is at its best. Front Street has also noticed that some friends choose to have Front Street grind the coffee for them due to the high fines rate of their home grinding equipment. It should be noted that after coffee is ground, the rate of flavor compound volatilization accelerates.

Therefore, Front Street recommends purchasing whole beans and grinding fresh for each brew to experience the best flavor. When friends first receive Front Street's coffee beans, they can see a beautiful blooming "hamburger" during brewing. The reason a blooming process is needed is to allow the coffee grounds to release their internal carbon dioxide gas, thereby making the subsequent extraction more stable.
