In recent years, with the wave of specialty coffee, Yunnan Arabica coffee has received significant attention as the pride of domestic Chinese products. As the only region in mainland China that cultivates Arabica coffee beans, what advantages does Yunnan coffee offer? FrontStreet Coffee will reveal the past and present of Yunnan coffee.

Yunnan Coffee's Century-Long History

Looking at the world, Yunnan's coffee history is relatively short but has spanned a century. In 1904, French missionary Alfred Tienne brought coffee seeds into Yunnan from abroad and successfully planted the first coffee tree in a village called Zhukula (now within Binchuan County, Dali). This marked the beginning of Yunnan's coffee cultivation history.

After 1930, the renowned overseas Chinese leader Mr. Liang Jinshan brought coffee to Pu Piao and Luoming for cultivation, continuing until after the founding of New China. After 1952, under the guidance of expert Ma Guojin from the Baoshan Tropical Economic Research Institute, areas like Lujiang began large-scale coffee cultivation, with nearly 60 years of large-scale cultivation history to date. During this period, all coffee varieties cultivated in Yunnan were Typica.

Subsequently, with further reform and opening up in 1992, foreign companies like Nestlé entered Yunnan to develop the coffee industry. At that time, they large-scale cultivated the Catimor variety provided by Nestlé, known for its high disease resistance and high yield. This quickly replaced Typica's position, which had excellent flavor but was delicate and weak, becoming Yunnan's primary coffee variety. However, Yunnan coffee's primary use at that time was selling to Nestlé as raw material for instant coffee.

By the end of 1997, the province's coffee cultivation area had reached 7,800 hectares. Currently, the province's cultivation area accounts for 70% of the national total, and production accounts for 83% of the national total. Whether measured by cultivation area or coffee bean production, Yunnan coffee has established a dominant position within China.

Today, starting from 2000, the wave of coffee specialization has swept the globe. China also experienced economic takeoff after 2008, with significant improvements in people's material living standards, which also promoted the development of domestic specialty coffee. Yunnan coffee has begun receiving attention from Chinese people.

Traditional Washed Processing of Yunnan Coffee

FrontStreet Coffee's Yunnan coffee beans typically use the washed processing method. The harvested cherries have most of their fruit pulp separated from the coffee beans using a depulping machine, then the parchment beans are guided to a clean water tank, soaked in water for fermentation to thoroughly remove the residual fruit pulp layer. In the past (about five years ago), the washed method was often the preferred choice for processing premium coffee beans.

Through water processing, underripe beans and defective beans are selected out due to buoyancy, and the fermentation process is easier to control. Therefore, unlike natural-processed beans that may have off-flavors, washed processing presents clear fruit acidity, slightly stronger complexity, and cleaner cup characteristics (without any negative flavors like astringency or sharpness).

Special Processing Methods in Yunnan

Today, Yunnan has also seen many emerging coffee processing methods, with various anaerobic processing techniques emerging one after another, creating highly recognizable unique flavors. Regarding these processing methods, FrontStreet Coffee believes they indeed have merit, but FrontStreet Coffee still insists on starting from the cultivation region and coffee varieties. Changes in processing methods only treat symptoms rather than root causes—Catimor will always be Catimor.

Only by selecting the correct cultivation altitude and premium-flavored coffee varieties from the source can sustainable long-term development for Yunnan coffee be achieved. Therefore, FrontStreet Coffee quietly began coffee cultivation in Yunnan as early as 2012. From seed to coffee bean, FrontStreet Coffee took 5 years. Therefore, FrontStreet Coffee still insists on using traditional processing methods like washed or natural for coffee processing.

FrontStreet Coffee Yunnan Huaguoshan

• Region: Baoshan, Yunnan
• Altitude: 1200m
• Variety: Typica
• Processing: Washed

FrontStreet Coffee Roasting Analysis

Yunnan Huaguoshan (Typica): FrontStreet Coffee chose medium-light roast for this bean. Yangjia 800N (300g batch size): Heat drum to 200°C, air damper set to 3. After 1 minute, adjust heat to 160°C. Return temperature at 1'32". Roast until yellowing at 5'40", temperature 149°C, grassy aroma completely disappeared, dehydration complete, heat unchanged, air damper adjusted to 4. At 6 minutes, heat adjusted to 140. At 7 minutes, heat further adjusted to 120. At 8 minutes, ugly wrinkles and black spots appear on bean surface, toast aroma clearly transforms to coffee aroma, can be defined as prelude to first crack. At this point, listen carefully for first crack sound. At 8'37", first crack begins, heat adjusted to 90, air damper fully open to 5. At 9 minutes, adjust heat down to 20 degrees. First crack development for 2'00", dropped at 196°C.

FrontStreet Coffee Cupping Report

FrontStreet Coffee conducts cupping within 8-24 hours after sample coffee bean roasting. FrontStreet Coffee's baristas typically use 200ml ceramic cupping bowls marked with 150ml and 200ml measurement lines. According to SCAA standards, water TDS is around 150ppm. TDS too low can easily cause over-extraction, while too high affects mouthfeel and can cause under-extraction. Cupping water temperature is 94°C. Cupping grind size follows SCAA cupping standards, controlled to 70%-75% pass-through rate for standard 20-mesh sieve (0.85mm). Ratio: 11g coffee powder plus 200ml hot water, i.e., 1:18.18, so extracted concentration falls within the 1.15%-1.35% golden cup range. Steeping time: 4 minutes.

Yunnan Huaguoshan coffee bean cupping: Rich fruit aroma on entry, melon, herbal plant fragrance. Smooth on entry, mid-palate nuts, milk chocolate, finish with lively and bright plum acidity, mouth-watering on both cheeks, good balance, medium body with full richness. From hot to warm temperatures, you can feel sweet and sour layering—sweet first then sour. Apricot, citrus-toned acidity. Black tea finish with some brown sugar.

FrontStreet Coffee Brewing Guide

When brewing these two washed Yunnan coffees, FrontStreet Coffee recommends aiming for balance—neither overemphasizing acidity nor excessively modifying the finish. Choose 15g coffee dose, brew ratio recommendation 1:15, or 1:16 if you want clearer flavors. Choose Kono dripper, 88°C brewing water temperature to make acidity softer. Grind: medium-fine/coarse sugar size (75% pass-through rate for 20-mesh sieve).

FrontStreet Coffee's Multi-Stage Pouring Technique

Use 30g water for 30-second bloom. When pouring with small water stream to 125g, create a stage division. When water level drops and is about to expose the coffee bed, continue pouring to 225g and stop. When water level drops and is about to expose the coffee bed, remove the dripper. Extraction time from bloom start: 2'00".

Through this brewing method, with Huaguoshan Typica coffee beans, you can taste distinct roasted nuts, soft acidity, overall balance and richness, solid dark chocolate aroma, and slight orange peel notes.
