Coffee variety knowledge in one guide—from the three great species to Yunnan's Typica.

FrontStreet Coffee · Coffee Varieties and Knowledge of the Three Major Coffee Species

Arabica

Also called small-bean coffee, Arabica originates in Ethiopia. Its trees mainly grow at altitudes between 1,000-2,000 meters; they are relatively cold-tolerant, thriving at 15-24°C, and demand high humidity with annual rainfall of at least 1,500 milliliters—plus skilled cultivation. Arabica trees are large shrubs with oval, dark green leaves. The fruits are oval too, usually holding two slightly flattened beans: long-oval on the front face with a narrow, curved S-shaped crease down the middle, and a relatively flat arc on the back. Caffeine content is about 0.8%-1.5%.

Arabica's excellent flavor and aroma make it the only one of the original species that can be drunk on its own as single origin. FrontStreet Coffee's Jamaican Blue Mountain, Indonesian Mandheling, Yirgacheffe, and Brazilian coffee are all Arabica single origins. But its resistance to drought, frost, pests, and diseases is weak—above all it cannot withstand coffee's greatest enemy, leaf rust—so every producing country works on variety improvement.

Arabica from different regions, altitudes, and climate zones shows completely different personalities. Unroasted it smells of fresh grass; properly roasted it shows "fruity aroma" at medium-light roast and "caramel flavor" at dark roast—suited to single origin or blends, and to all kinds of extraction methods.

Robusta

Also called medium-bean coffee, Robusta originates in Congo, Africa. Its trees are planted mostly in lowlands at 200-800 meters, preferring warm climates of 24-29°C, with modest rainfall needs. This variety relies on insects or wind for pollination, so it takes 9-11 months from pollination to fruit—longer than Arabica.

Yunnan Small-Bean Coffee

Rubiaceae, genus Coffea. Yunnan's planting areas are mainly distributed across Lincang, Baoshan, Simao, Xishuangbanna, and Dehong prefectures. Small-bean coffee traces back to Ethiopia or the Arabian Peninsula.

Typica

Typica coffee originates in southeastern Ethiopia and Sudan and is the most widely planted variety in the Western Hemisphere. The plants are robust but intolerant of strong light, with notably high yields in Hawaii. Typica's top leaves are bronze-colored—hence "red-top" coffee. Typica is recognized as a specialty variety, and many commercial improved varieties descend from it. Flavor is excellent, but yields are extremely low, it is susceptible to rust disease, and it demands heavy labor.

Typica beans are slender, the trees tall with oval fruits and slightly drooping branches. Typica carries four slender, spreading branches at an inclination of 50-70 degrees. Yield per tree is very low—but the cupping score is very high.

Knowledge Extension

Robusta's value is not to serve as a negative example for Arabica; it holds an unshakable place in espresso blends. Italian blends add a small amount of Robusta to increase body and produce espresso with richer crema.

FrontStreet Coffee Recommendation

Ethiopia is the cradle of all these varieties, and its most famous town is Yirgacheffe—perched at roughly 1,700-2,100 meters with coffee planted above 1,800 meters, among the highest coffee zones on earth. In 2010 the Ethiopian Commodity Exchange formally separated Yirgacheffe from Sidamo because its name had grown so famous; since then it has been a byword for distinctive white florals and lemon-citrus acidity.

FrontStreet Coffee's classic washed Yirgacheffe everyday lot is the ideal first taste of the region: white jasmine, bright citrus and lemon acidity, a tea-like finish, and an approachable price.

For a village-level expression, FrontStreet's Gotiti Cooperative lot—from Gotiti village in the Worka zone, once part of the YCFCU cooperative union—delivers luminous citrus, jasmine fragrance, and a clean cup with none of the traditional bitterness, through the most traditional washed processing.
