How to Distinguish Between Yunnan Typica and Catimor Coffee Beans

Typica and Catimor: Are They Both Yunnan Small-Bean Coffees?

Yunnan small-bean coffee belongs to the Rubiaceae family and the Coffea genus. Plantings are concentrated in Lincang, Baoshan, Simao, Xishuangbanna, Dehong, and other prefectures, and the small-bean type itself originated in Ethiopia or on the Arabian Peninsula. What follows is a closer look at how Typica and Catimor differ.

Where It Grows

Small-bean coffee prefers mountain areas at elevations of 800–1800 meters. Too high and the cup turns sour; too low and it turns bitter. Most Yunnan small-bean is planted in dry-hot valley areas around 1100 meters, which yields moderate acidity, a rich fragrance, and a mellow taste. Many parts of Yunnan have environments well suited to the variety and produce excellent lots.

Baoshan has an average temperature of 21.5°C, reaching up to 40.4°C at its hottest, with essentially no frost all year, making it a recognized leading area for small-bean coffee. The coffee grown there is known at home and abroad for being rich without bitterness and fragrant without harshness, with small, uniform beans and a lush mellow fragrance plus fruit notes. Tasting experts from the International Coffee Organization have placed Yunnan coffee in the same category as Colombian washed small-bean coffee, among the world's highest-quality coffees.

The Two Varieties

Typica is the oldest native variety from Ethiopia, originating in southeastern Ethiopia and Sudan. All Arabica varieties descend from Typica. It has an elegant flavor but a weak constitution, poor disease resistance, and low yield. Famous estate coffees such as Jamaica Blue Mountain, Sumatra Mandheling, and Hawaii Kona are all Typica. The top leaves of Typica are bronze-colored, which is why it is also called red-top coffee. Typica belongs to the Arabica species.

Catimor was created in 1959, when Portuguese breeders crossed Brazilian Caturra with Timor to produce a strongly disease-resistant variety that has since become an important commercial coffee.

Growth and Flowering

Yunnan small-bean coffee trees begin to bear fruit at 3–4 years of age.

Coffee is a short-day plant with both multiple and concentrated flowering periods. Yunnan small-bean flowers from February to July, peaking from March to May. Flowering is strongly influenced by climate, especially rainfall and temperature. Coffee flowers are short-lived, lasting only 2–3 days, and small-bean coffee generally begins to open between 3 and 5 AM, reaching full bloom between 5 and 7 AM.

Fruit development takes a relatively long time. Small-bean fruit needs 8–10 months to mature, generally ripening from October to December. Rainfall has a significant effect on fruit development, and climatic conditions directly shape the final cherry.

In the photo above, the new leaves at the tips of the branches are bronze-colored — that is the Typica tree. Typica is an old variety in the Arabica lineage; the well-known Hawaii Kona and Jamaica Blue Mountain are also Typica. In a large field of Catimor it is quite easy to spot once you know what to look for: Catimor leaves all droop downward and the tree looks as if it is wearing a cloak, while Typica branches point upward and the tree tips carry bronze new leaves.

Looking at the whole picture, most of what is planted in Yunnan today is Catimor, a hybrid between the Caturra branch of the Arabica Bourbon lineage and the Robusta lineage. Farmers favor it because Catimor carries Robusta genes, giving it better disease resistance than the single old varieties as well as good yield. Compared with delicate old varieties that resist disease poorly and yield little, farmers naturally choose Catimor, and that preference has now swept across Yunnan.

Catimor beans are round and thick, while Typica beans are thin and long, and the center line of Catimor is disordered. Under the same conditions, Typica's quality is superior to Catimor's, and its price is higher as well.

FrontStreet Coffee Recommendation

For an approachable introduction to Yunnan, FrontStreet's Yunnan small-bean coffee is a natural first step. Sourced from the Baoshan region and given a washed process and a medium roast, it shows soft nut and chocolate sweetness with a light plum acidity — an affordable way to meet Yunnan coffee for the first time.

If you want something with more definition, FrontStreet's 2013 Yunnan Natural Typica comes from FrontStreet's own estate. Typica is one of the oldest and purest Arabica varieties, and the team uses the most traditional post-harvest method, natural sun-drying, on fully ripe red cherries. After a medium roast the cup is fuller-bodied with more pronounced sweet-acid balance: dark berry notes, caramel sweetness, chocolate, a hint of dried apricot, and a black-tea finish.

To taste Yunnan in an espresso blend, FrontStreet's Black Cocoa Blend combines Yunnan small-bean with Brazil Cerrado. The Brazil component supplies mixed-nut aroma and a balanced body, while the Yunnan small-bean handles chocolate and citrus. The resulting Americano is balanced across acidity, sweetness, and bitterness with nut and brown-sugar notes, and as a latte it brings out almond and cream with a smooth, silky texture — an easy starting point for beginners.
