Is Yunnan Baoshan Small Bean Coffee an Arabica Variety? What to Do When Pour-Over Small Bean Coffee Tastes Bitter

Introduction to Yunnan Coffee Bean Growing Regions

Yunnan small-seed coffee grows best on mountainous terrain at altitudes of 800 to 1,800 meters. Too high an altitude turns the taste sour; too low makes it bitter. Most Yunnan small-seed coffee is planted in dry, hot valley areas at around 1,100 meters, resulting in moderate acidity, a rich fragrance, and a mellow flavor. Many areas of Yunnan offer environments uniquely suited to small-seed coffee, producing excellent quality.

The main growing areas are distributed across Lincang, Baoshan, Simao, Xishuangbanna, and Dehong, among other prefectures. Baoshan has an average temperature of 21.5°C, reaching as high as 40.4°C, with basically no frost throughout the year, making it recognized as the best small-seed coffee producing area. The small-seed coffee grown here is famous at home and abroad for being rich but not bitter, fragrant but not overpowering, with small, uniform beans, a rich, mellow aroma, and fruity notes. Tasting experts from the International Coffee Organization have rated Yunnan coffee as equivalent to Colombian wet-processed small-seed coffee, among the highest quality coffee in the world.

Growing Altitude

For Arabica, 1,200 meters is the quality watershed. Note that Hainan coffee, which few people talk about, has remained non-mainstream and is sold mainly as a tourist souvenir. This is partly because it is Robusta, and partly because Hainan's terrain sits at sea level, with most areas below 300 meters. Although the central Wuzhishan peak reaches 1,800 meters, the urban area is only 320 meters. Hainan can grow some souvenir coffee, but it lacks the capacity to cultivate good Arabica.

Since growing altitude is a fundamental factor, large areas of Yunnan's mountains reach above 1,000 meters. Kunming sits at 1,895 meters, Baoshan at 1,653.5 meters, Dali at 1,976 meters, Chuxiong at 1,773 meters, Dehong averages 800-1,500 meters, and Diqing averages 3,380 meters. At higher altitudes, temperature must also be considered. Generally, the golden coffee belt lies between the Tropics of Cancer and Capricorn, because outside this zone the probability of frost becomes very high, and coffee trees die when they encounter frost. Yunnan, however, is protected by the Gaoligong Mountains north of Baoshan, which block the driving influence of Siberian cold currents in winter, and its many mountains form protective microclimates for coffee growth.

Processing Methods

The harvested cherries are processed through a depulping machine that separates most of the fruit pulp from the beans, then the parchment beans are guided to a clean water tank and soaked to ferment, completely removing the remaining pulp layer. In the past, about five years ago, the washed method was often the preferred choice for processing high-quality coffee beans.

Through water processing, unripe and defective beans are removed by buoyancy, and fermentation is easier to control. In terms of flavor, unlike natural processed beans, which may carry impurities, washed coffee presents distinct fruit acidity, slightly stronger complexity, and cleaner cup characteristics, without any negative flavors such as astringency or sharpness. However, because it is so "clean," the richness of flavor is somewhat weaker.

Green Bean Analysis

FrontStreet Coffee · Yunnan Huaguoshan · Yunnan Small-Seed Coffee Beans

Yunnan small-seed coffee belongs to the Rubiaceae family, Coffea genus, with growing areas mainly distributed across Lincang, Baoshan, Simao, Xishuangbanna, and Dehong, among other prefectures. Small-seed coffee originates from Ethiopia or the Arabian Peninsula.

Variety

Typica: The oldest native variety from Ethiopia, grown in southeastern Ethiopia and Sudan. All Arabica varieties are derived from Typica. It has an elegant flavor but a weak constitution, poor disease resistance, and low fruit yield. FrontStreet Coffee's Jamaica Blue Mountain, FrontStreet Coffee's Indonesia Sumatra Mandheling, FrontStreet Coffee's Hawaii Kona, and other excellent estate beans all belong to Typica. Typica has reddish-brown terminal leaves, called red-topped coffee, and belongs to the Arabica species.

Coffee trees have opposite, long-oval leaves with smooth surfaces. The terminal branches are long with few side branches, while the flowers are white and bloom at the base where the petiole connects to the branch. Mature coffee cherries resemble cherries, bright red in color, with sweet pulp containing a pair of seeds, the coffee beans.

Typica is one of the oldest native varieties of Arabica coffee discovered to date. Its terminal leaves are bronze-colored, and the beans are oval or slender-pointed; it has an elegant flavor but a weak constitution, poor disease resistance, and low fruit yield.

Typica is one of the oldest varieties of Arabica coffee trees discovered today, along with Bourbon. Arabica originated in Ethiopia, where the species still grows naturally in the pristine rainforest highlands. The Typica planted in Java was a gift from the Dutch to honor France's Louis XIV, survived in the Persian Garden, and its seeds were brought by the French to the colony of Martinique in 1720.

Typica beans are slender, the tree is tall, the fruits are oval, and the branches are slightly inclined. Typica has four long branches in an open posture, with an inclination angle of 50-70 degrees. The coffee yield per tree is very low, but cupping scores are very high.

Roasting Analysis

For this FrontStreet Coffee Yunnan Huaguoshan washed Typica coffee, a medium-slow roast is planned to best showcase its round, smooth characteristics while maintaining rich floral and fruit aromas.

Roaster: Yangjia 600g semi-direct heat

Preheat the roaster to 200°C, then load the beans with the damper set to 3. After 30 seconds, adjust the heat to 160°C, keeping the damper unchanged. The temperature return point is at 1'33". Adjust the heat once at 168°C, when the bean surface turns yellow and the grassy smell disappears completely, indicating dehydration is complete. Adjust the heat to 130°C and the damper to 4.

At 8'45", ugly wrinkles and black markings appear on the bean surface, and the toast aroma clearly transitions to coffee aroma. This can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. First crack begins at 9'07"; reduce heat to 80°C and open the damper fully to 5 (adjust heat very carefully, not so low that there is no cracking sound). Three minutes after first crack, unload at 198°C.

Cupping:

Dry Aroma: Pear-like fruits, vanilla-like, honey-like, peach tea, ripe orange, jasmine hints

Wet Aroma: Nutty, milky chocolate, herbal-floral

Flavor: Smooth entry, Asian herbal plant aroma, lively and bright acidity, mouth-watering on both cheeks, soft acidity with a good balance between thickness and richness, layered complexity, with obvious dark chocolate, honey, and sucrose notes in the aftertaste. After complete cooling, brown sugar flavors emerge.
