A Brief Introduction to Yunnan Typica Coffee Beans: Grind Settings, Roast Levels, and Processing Methods

FrontStreet Coffee · Introduction to Yunnan Coffee Varieties: Catimor and Typica Coffee Bean Cultivation

Before going there, Brother Zou told me his relative's family still had a plot of old-variety coffee trees. I rushed over excitedly, only to find a patch of wildly growing coffee trees. This land belonged to his aunt, who, being advanced in age, no longer had the strength to renovate and replant. That is why these old varieties survived - but his aunt alone could not manage them properly, so she let the trees grow naturally and picked only some fruit when it ripened.

Classic Coffee Varieties in Yunnan

Typica and Bourbon, two classic premium coffee varieties, are the main cultivated varieties in Yunnan. In 1991 the Catimor series was introduced from Kenya (stronger disease resistance and higher yield). They belong to the Arabica species (also known as small-seeded variety). Because the two varieties are similar in morphology and habit, they are often mixed in cultivation.

Typica Coffee

Typica originated in southeastern Ethiopia and Sudan and is the most widely cultivated coffee variety in the Western Hemisphere. The plants are relatively robust but not tolerant of strong sunlight, and yields are higher in Hawaii. The top leaves of Typica are reddish-bronze, giving it the name "red-topped coffee."

Bourbon Coffee

Bourbon is the second most important variety after Typica among small-seeded coffees. The main branches initially grow upward at a 45-degree angle to the trunk, then droop as the fruit load increases. The side-branch nodes are denser, producing more fruit and higher yields, though the berries are smaller and mature more slowly. The top buds and young leaves of Bourbon are green, giving it the name "green-topped coffee."

Catimor Coffee Beans

Catimor is not purely of Arabica bloodline; it is a hybrid between Timor (which belongs to the Robusta species) and Caturra (a Bourbon variety). Catimor therefore carries 25% Robusta bloodline, and that heritage determines its flavor defects: insufficient aroma richness, prominent bitterness, and a tendency toward astringency and relatively pungent musty flavors.

All coffee planted in the Pu'er region of Yunnan is of the Catimor variety. Baoshan City introduced Typica and Bourbon as early as the 1950s, and locals call them "old varieties." Because old varieties have lower disease and pest resistance and yield and are more labor-intensive to manage - coupled with the lack of any significant price advantage in market purchases - coffee farmers have recently switched to planting the new Catimor variety.

From the botanical perspective of coffee, Yunnan small-seeded coffee shares genetic similarities with the world-renowned Jamaica Blue Mountain and Hawaii Kona coffees.

Characteristics of Yunnan Coffee

Yunnan coffee, thanks to its unique geographical environment and climate, has developed a distinctive flavor profile that is rich but not bitter, aromatic but not overpowering, with a hint of fruitiness. World-class coffee experts have rated it among the finest coffees globally, with its cultivation techniques and yield per unit also being world-class.

Yunnan coffee belongs to a variant of the Arabica species, formed through long-term cultivation and domestication, generally called Yunnan small-seeded coffee. It is an evergreen small shrub with smaller beans, thicker fruit skin, sweet pulp, and an aromatic product with lower caffeine content - hence it is also called "mild coffee." It is one of the world's main cultivated varieties.

Growing Conditions and Processing

Coffee quality is determined by various factors, including growing environment, climate and cultivation management. The optimal growing environment is characterized by low latitude, high altitude, sufficient rainfall and appropriate sunlight. The region between 15°N latitude and the Tropic of Cancer is therefore the ideal growing zone for coffee.

Our company's planting base in Yunnan is located at 23°N latitude and 99°E longitude, with altitudes ranging from 1,230 to 1,540 meters above sea level - a difference of 310 meters. The terrain is mainly mountainous and sloped with significant variation, with fertile soil, abundant sunlight, plentiful rainfall and large day-night temperature differences. These unique natural conditions create the special taste profile of Yunnan coffee: rich but not bitter, aromatic but not overpowering, with a slight fruitiness, and quality comparable to Colombian small-seeded coffee.

Coffee cherries are generally harvested from November to February each year and processed using the washed method. Processing uses advanced imported equipment. Currently, 30% of Yunnan coffee products supply the domestic market, while 70% are exported abroad.

Seeking Old Varieties

Later I went to Zhang Bao's younger brother's village on another high mountain. The nearby peaks are all the village's coffee gardens, but the entire village currently has only two mu of old varieties remaining. Fortunately, this family managed them well, so they still looked very healthy and were still in the harvesting period, allowing me to see well-ripened red coffee cherries.

After discussing with the owner, we decided to buy back 10 kilograms of green beans to taste. The cherries picked at the end of the previous year were still stored in the warehouse in parchment form. Early the next morning we went together to hull and process them. After hulling we got 18.5 kilograms of green beans of varying sizes, with many broken, small and defective beans. Even after sorting by size, many defective beans remained, so we sorted them by hand on the spot. After final selection, only 9 kilograms of qualified beans were left, and by then most of the morning had passed.

Of course, if used for instant coffee or general commercial beans, the high-yield Catimor is a good choice. But if you are seeking Yunnan's specialty coffee, the old-variety Typica becomes the first choice because of its inherently superior genetics. During this trip to Yunnan, I followed the traces of old varieties throughout the journey - though the reality proved quite harsh.

FrontStreet Coffee Recommendation

If following those old-variety traces leaves you wanting to taste the result, FrontStreet Coffee 2013 Natural Typica is the clearest expression of Typica in Yunnan. Grown on FrontStreet Coffee's own estate in Lincang from fully ripe red cherries, it is sun-dried and medium-roasted for balance and pronounced sweetness and acidity, showing dark berries, caramel, chocolate and a hint of dried apricot with a black-tea finish. It is the natural next step for anyone drawn to Yunnan's "old varieties."

For an everyday introduction to the region, FrontStreet's Yunnan Xiaoli coffee comes from the Baoshan producing area, washed and medium-roasted to show soft nut and chocolate sweetness with a light plum acidity at a friendly price - the first taste of Yunnan coffee for many drinkers.
