Yunnan Premium Coffee Beans from Baoshan Region: Sun-Processed Yunnan Small Bean Coffee Brewing Flavor Profile

Among the daily coffee bean series at FrontStreet Coffee, China's Yunnan small-bean coffee has caught the attention of many enthusiasts. Yunnan beans were once dismissed as poor in quality and flavour, but as the specialty coffee industry has developed, they have emerged as a dark horse.

Yunnan Coffee Varieties at FrontStreet Coffee

At FrontStreet Coffee you will find two Yunnan varieties: a washed Typica and a Catimor. The Yunnan Typica is labelled as Yunnan specialty coffee, while the Yunnan Catimor is labelled, following market custom, as Yunnan small-bean coffee. FrontStreet roasts both to a medium level, because Yunnan is not an acidic region and the beans are relatively balanced, with base notes of nuts and brown sugar.

The Yunnan small-bean coffee in FrontStreet Coffee's daily bean series is sold in small packages at the most affordable prices, so curious drinkers can sample the balanced character of the region together with its nutty, brown sugar sweetness and gentle fruit acidity.

Yunnan Baoshan Coffee Region

Yunnan small-bean coffee suits mountainous terrain between 800 and 1800 meters. Too high and the cup turns acidic; too low and it turns bitter. Most of the crop is planted in dry, hot valley areas at around 1100 meters, which produces moderate acidity, a rich fragrance and a mellow flavour. Many parts of Yunnan have environments uniquely suited to small-bean coffee, and they deliver excellent quality.

The main growing areas are spread across Lincang, Baoshan, Simao, Xishuangbanna and Dehong. Baoshan has an average temperature of 21.5°C, reaching up to 40.4°C at its maximum, with essentially no frost all year — widely recognised as the best small-bean coffee district. Coffee grown here is known at home and abroad for being strong but not bitter, fragrant but not harsh, with small, uniform beans, a rich mellow fragrance and fruity notes.

International coffee organisation tasting experts have placed Yunnan coffee in the same category as Colombian wet-processed small-bean coffee, the highest quality coffee in the world.

Small-Bean Coffee Varieties

The main varieties cultivated in Yunnan today are Catimor, Typica, Bourbon, Caturra and Catuai, among others, but almost all the coffee found on the market is Catimor. Yunnan small-bean coffee therefore now means Yunnan Catimor.

In 1959, Portuguese growers moved the Bourbon mutation Caturra from Brazil to East Timor and crossed it with Timor, which carries Robusta blood, successfully producing Catimor with strong disease resistance and high productivity. As leaf rust spread through coffee-producing countries, international organisations helped producing nations promote Catimor widely to resist the disease and raise output.

Coffee Bean Processing

Because Yunnan has a long rainy season and an unstable climate, most of its coffee is processed by the washed method.

The harvested cherry goes through a depulper to separate most of the pulp, then the parchment beans are guided into a clean water tank and soaked to ferment, thoroughly removing the remaining mucilage. A few years ago, washing was still the automatic first choice for high-quality processing.

Washing uses differences in buoyancy to sort out unripe and defective beans, and fermentation is easier to control. Unlike natural beans, which may carry impurities, washed beans present distinct fruit acidity, slightly greater complexity and a cleaner cup without astringency or sharpness. The trade-off is that such a "clean" cup can be a little less rich in flavour.

FrontStreet Coffee Roasting Record

Roaster: Yangjia 800N (roasting amount: 300g)

Charge at 190°C, heat at 120, damper at 3; the temperature returns to the turning point at 1'40". When the drum temperature reaches 145°C, open the damper to 4, heat unchanged. At 166°C the bean surface turns yellow, the grassy aroma disappears completely and the dehydration stage begins. At 188°C, adjust the heat to 60, damper at 5.

At 8'37", ugly wrinkles and black spots appear on the bean surface and the toast aroma clearly turns to coffee aroma — the prelude to first crack. Listen closely from here. First crack begins at 9'00"; the damper stays as it is, develop for 3 minutes after first crack, and discharge at 198°C.

FrontStreet Coffee Brewing Recommendations

Dripper: V60

Dose: 15g

Water Temperature: 90°C

Grind Size: 80% pass-through rate on standard #20 sieve

Water-to-Coffee Ratio: 1:15

FrontStreet Coffee Brewing Technique

Use 30g of water for the bloom, bloom time 30s. First pour to 125g and stop: vertical water flow, small flow, slow circular motion. Second pour to 225g with a slightly faster flow and circle to keep fine particles from clogging the filter and over-extracting. Timing starts from the bloom; extraction time is 2 minutes.

Brewing Flavor

A rich nutty aroma on the nose, with herbal, chocolate and caramel notes in the mouth, and a light fruit acidity in the aftertaste.

FrontStreet Coffee Recommendation

FrontStreet Yunnan Small Bean comes from Baoshan and is washed and medium roasted. Coffee reached Yunnan in 1904, when the French missionary Tian Deneng brought Typica seed from Vietnam and planted the first tree in Zhugula village, Binchuan county; Baoshan's commercial history began later, in the mid-1950s, when the overseas Chinese entrepreneur Liang Jinshan introduced the crop. The dry-hot valley climate around Lujiangba, with its wide day-night temperature swing and modest, well-judged rainfall, is what gives Baoshan small bean its distinctive sweetness. It highlights a measure of caramel while retaining some acidity, so the terroir of the region comes through clearly — the natural first choice for anyone buying an entry-level Chinese Arabica.

FrontStreet 2013 Sun-Dried Typica is the step up for drinkers who want a sharper picture of Yunnan. Grown on FrontStreet's own estate, it uses the oldest and most traditional post-harvest method, natural sun-drying. Typica is one of the oldest and purest Arabica varieties, and after natural processing the cup is heavier and more sweet-tart, with citrus and berry tones, a faint fermented wine note, caramel sweetness and a creamy finish.

FrontStreet Black Cocoa Blend brings Yunnan into espresso. Combining Yunnan small bean with Brazil Cerrado, it lets the Brazilian component provide mixed-nut aroma and balance while the Yunnan component handles chocolate and citrus. Pulled as an americano the acidity, sweetness and bitterness are balanced, with nutty and brown sugar sweetness; as a latte it turns silky, with almond and cream — very approachable for beginners.
