The Evolution of Yunnan Coffee

Historically, Yunnan coffee has not had the best reputation. Partly this was because more scientific cultivation methods were not yet in use, and partly because Yunnan-grown coffee was supplied primarily to Nestle for instant coffee production, so the beans were never processed with particular care.

Times have changed, however. Today, with support from local authorities, far more research goes into Yunnan coffee cultivation. Driven by specialty coffee culture, Yunnan coffee now receives serious attention at every stage from growing to processing, and the quality has improved dramatically in recent years. Thanks to these collective efforts, Yunnan coffee has developed its own regional flavor signature: plums, nuts, caramel, and tea-like notes.

FrontStreet Coffee's Yunnan Selection

In FrontStreet Coffee's daily bean lineup, the representative Yunnan offering is a washed Catimor from the Baoshan growing area. Baoshan was chosen because its altitude and mild climate suit specialty coffee production. Typically, 1200 meters is the dividing line between commercial and specialty coffee, and as a general rule, the higher the cultivation altitude, the better the flavor.

The beans FrontStreet Coffee selects are grown above 1200m in Baoshan. The washed process, with 18-36 hours of fermentation in water tanks after depulping, enhances this coffee's bright acidity and makes the overall cup cleaner, letting you appreciate the bean's quality and Yunnan's regional character more directly.

When FrontStreet Coffee received these Yunnan Catimor small-bean green coffees, we noted that the beans were uniform overall with a greenish color, carrying a faint grassy aroma and a plum-like acidic fragrance.

Roasting Approach

Because this variety is an Arabica with a small amount of Robusta genetics, its inherent green, raw flavors run slightly stronger than in other Arabica varieties. To minimize that greenness while showcasing Yunnan's regional character, FrontStreet Coffee roasts the beans to a medium level, presenting a cinnamon-stick color.

Yangjia 800N roaster (300g batch): charge temperature 190°C, heat at 120, damper at 3; turning point at 1'40"; when the temperature reaches 145°C, open the damper to 4 with heat unchanged; at 166°C the bean surface yellows and the grassy aroma disappears completely, entering the drying stage; at 188°C, reduce heat to 60 and set the damper to 5.

At 8'37", wrinkles and black spots appear on the bean surface and the toast aroma clearly transitions to coffee aroma, the prelude to first crack, so listen carefully from here. At 9'00" first crack begins; keep the damper unchanged, develop for 3 minutes after first crack, and drop the beans at 198°C.

Brewing Recommendations

FrontStreet Coffee's Yunnan small-bean brewing suggestions:

Dripper: Hario V60

Dose: 15g

Water Temperature: 90°C

Grind Size: 75% pass-through rate on a #20 sieve

Water-to-Coffee Ratio: 1:15

Three-stage pour: use twice the coffee weight in water to moisten the bed, letting it dome and bloom for 30s. Then use a small stream to pour in circles from the center outward to 125g for the second stage. Once the coffee bed drops to half the dripper's height, continue with the same fine stream for the third stage up to 225g. Remove the dripper once all the liquid has drained through; total time is approximately 2 minutes.

FrontStreet Coffee Recommendation

"Yunnan small beans" is simply the local name for Arabica, the smallest-seeded of the three coffee species, and the story goes back to 1904, when the French missionary Tian Deneng brought Typica seeds from Vietnam into Yunnan and planted the first coffee tree in Zhugula Village, Binchuan County. Yunnan's warm, frost-free climate, fertile hillside soils, and strong day-night temperature swings make it ideal growing country, with cultivation concentrated in the southwest across Baoshan, Dehong, Pu'er, and Lincang.

If this washed Baoshan Catimor is your gateway to Yunnan, FrontStreet Coffee's 2013 Yunnan sun-dried Typica is the next step: grown on FrontStreet's own estate from fully ripe red cherries and naturally processed, then roasted medium for balance, it carries dark berry and citrus tones with caramel sweetness, chocolate, a hint of dried apricot, and a black-tea finish. And for Yunnan flavor in espresso, FrontStreet Coffee's Dark Cocoa Blend pairs Yunnan small beans with Brazil Cerrado: Brazil contributes mixed nut aromas and balance while Yunnan adds chocolate and citrus, producing a well-balanced Americano with nutty, brown-sugar sweetness and a silky almond-and-cream latte, a great choice for beginners.
