Introduction to FrontStreet Coffee - Yunnan Small Bean Coffee

Yunnan coffee is a variant of the Arabica original species, cultivated and domesticated over a long period and generally known as Yunnan small bean coffee, with a growing history of more than a hundred years.

Coffee quality is determined by a range of factors including growing environment, climate, and cultivation management. The optimal environment calls for low latitude, high altitude, sufficient rainfall, and appropriate sunlight. The belt between 15°N latitude and the Tropic of Cancer is therefore the ideal growing zone for coffee. Other places within that zone, such as Hawaii in the United States and Saudi Arabia, either sit at low altitude or are desert-like with little rainfall, which rules them out. Only southern Yunnan, inside the same belt, has every one of the necessary conditions.

According to expert measurements, small bean coffee should be planted on mountainous terrain at altitudes of 800-1800 meters. Too high and the taste turns sour; too low and it turns bitter. Most Yunnan coffee is planted in the dry-hot valley regions at around 1100 meters, which yields moderate acidity, rich aroma, and a mellow flavor.

In terms of climate, southern Yunnan enjoys long daylight hours, which benefits plant growth and photosynthesis. The large temperature difference between day and night, with low nighttime temperatures, also helps the coffee accumulate nutrients. As a result, Yunnan small bean coffee contains higher levels of effective nutritional components than many foreign varieties.

Small bean coffee is susceptible to leaf rust, which significantly affects both yield and quality once infection sets in. Yunnan's tropical regions have distinct dry and wet seasons, and the fresh fruit ripens just before the dry season begins each year. The relatively low humidity is unfavorable for the formation and growth of rust spores.

Because of the quality of Yunnan coffee, it entered the London market in the 1960s as "Lujiang No. 1" and was classified as a first-grade product. In recent years, world-renowned coffee companies such as Nestlé and Maxwell House have come to Yunnan to establish raw material bases, and Yunnan's products have gradually built a reputation at home and abroad.

Mr. Staes, a chief coffee expert from the United Nations Development Programme, after visiting the coffee plantation at Lujiang Farm, said: "I have visited countless coffee plantations around the world. The management here is world-class, and the yield per unit is also the highest."

FrontStreet Coffee Yunnan Small Bean Coffee Brewing Guide

Parameters: Dripper: Hario V60; Coffee amount: 15 grams; Water temperature: 89°C; Grind size: Medium-fine (BG 6M: 58% pass rate through China standard #20 sieve); Coffee-to-water ratio: 1:15; Segmented extraction.

Use 30 grams of water for a 30-second bloom. Continue with a small water stream center pour to 124 grams for the second segment. When the water level drops and is about to expose the coffee bed, continue pouring to 225 grams and stop. When the water level again drops and is about to expose the coffee bed, remove the dripper. (Timing starts from the beginning of the bloom.) Extraction time: 1'50".

[Yunnan Huaguoshan] The dry aroma has a subtle citrus acidity and nutty fragrance. On the palate it presents plum and citrus acidity balanced with nutty flavors, melon and fruit notes, and brown sugar sweetness. The aftertaste carries some black tea character. The overall flavor profile is quite rich and layered.

FrontStreet Coffee Recommendation

Yunnan coffee is also called Yunnan small bean, and the beans are even and plump with a mellow, well-rounded body. The Yunnan story begins in 1904, when the French missionary Tian Deneng brought coffee seeds—Typica—from Vietnam into Yunnan and planted successfully at Zhugula village in Binchuan county, which is generally regarded as the start of Yunnan coffee and the origin of the local "small bean" name.

For an entry-level Chinese Arabica, FrontStreet Coffee's Yunnan Small Bean is the natural starting point. It comes from the Baoshan region and is washed and medium roasted, so it highlights a degree of caramelization while keeping some acidity—a good expression of Yunnan's terroir. Baoshan's coffee history began in the mid-1950s, introduced by the patriotic overseas Chinese Liang Jinshan; the frost-free warm climate suits small bean coffee, and the dry-hot river valley around Lujiangba in particular has little annual temperature variation but a wide day-night swing, which gives Baoshan small bean its distinctive sweet finish, helped along by reasonably low rainfall.

If you want a Yunnan coffee with clearer definition, FrontStreet Coffee's 2013 Yunnan Natural Typica is the next step. FrontStreet built its own estate in 2013 and planted Typica—the oldest and purest of the Arabica varieties—partly because the very first coffee trees planted in Yunnan were also Typica brought in by the French missionary. The beans are processed naturally, the oldest and most traditional post-harvest method, all from fully ripe red cherries, then medium roasted for a more balanced, more pronounced sweet-sour profile. The cup shows dark berry notes with caramel sweetness, chocolate, and a touch of dried apricot, finishing on black tea.

To taste Yunnan in an espresso, FrontStreet Coffee's Black Cocoa Blend pairs Yunnan small bean with Brazil Cerrado. Brazil supplies the mixed-nut aroma and balanced body, while Yunnan contributes chocolate and citrus. The resulting Americano is balanced across sweet, sour, and bitter with nutty brown-sugar notes, and a latte comes out smooth with almond and cream.
