FrontStreet Coffee - Arabica Varieties and Yunnan Typica Introduction

The Arabica species began with Typica coffee beans from Martinique Island and Bourbon coffee beans from Réunion Island, from which today's many varieties descend.

Among the coffee trees shipped to Réunion Island, some underwent accidental genetic mutations, giving rise to Bourbon coffee beans. Although this variety gained recognition, similar mutations kept occurring, producing new varieties. A representative one is Caturra, a mutated form of Bourbon characterized by early maturity and high yield, widely cultivated in Central and South America. Maragogipe, the largest-fruited variety among Arabica, also arose through genetic mutation.

Different variety combinations, or hybridization, can also produce new varieties. Mundo Novo, cultivated in Brazil, resulted from natural hybridization between Sumatra (a subspecies of Typica) and Bourbon. Catuai, produced from Mundo Novo and Caturra, is an artificially hybridized variety. When artificially hybridizing coffee varieties, the stamens must be removed before flowering to prevent pollen from reaching the pistil—a process called "emasculation." Hybrid varieties such as Colombia, Icatu and Ruiru 11 are all artificially hybridized.

Geisha coffee beans, which have drawn widespread attention since 2006, originally grew quietly in the Geisha region of Ethiopia until they were exported to other regions in 1960. Like Typica, it is an ancient variety, with Panamanian Geisha the most famous. It was produced at CATIE (Tropical Agricultural Research Center) in Costa Rica and is widely loved for its unique aroma reminiscent of Mocha.

Typica green beans have slightly curved ends and an oval shape. From the side, the bean body appears thin and flat. Even when cultivated at different altitudes, the thickness on the side of the green beans won't vary significantly.

Unlike other bean varieties, Typica coffee fruits are cone-shaped. Typica coffee is of extremely high quality and therefore very popular among plantations worldwide. When properly cultivated, Typica offers high sweetness, pure flavor and pleasant acidity. Yunnan Typica features an Asian herbal plant aroma, lively and bright acidity, a mouth-watering sensation, balanced soft acidity and richness, rich layers, with distinct afternotes of dark chocolate, honey and cane sugar. When completely cooled, it reveals brown sugar flavors.

Yunnan Typica coffee is the oldest variety in Yunnan and is extremely rare. Size: 17 screen and above, altitude: 1200 meters and above, fruit acidity: relatively strong. Characteristics: fresh coffee green beans of the season, fragrant and rich, a delicate and smooth taste, good fruit acidity—an extremely personalized premium product.

Knowledge Point: Mundo Novo belongs to the natural hybrid of Bourbon and Sumatra Typica, first discovered in Brazil, hailed as the new hope of Brazil's coffee industry and hence named the "New World" variety.

FrontStreet Coffee Recommendation

Since this article touches on Geisha as one of the great Arabica varieties, FrontStreet Coffee's Geisha selection is a good next step. Geisha is loved for its distinctive florals and superb sweet-sour balance, but low yields, weak disease resistance and demanding cultivation have kept prices high, so it pays to know the tiers. The Esmeralda estate's line is split into Red Label and Green Label: FrontStreet Coffee's Red Label Geisha, officially "Esmeralda Special," is grown at 1,600-1,800 meters, and each lot—such as the Jaramillo lot—must cup above 90 points and carries its own number, so buyers can pick a lot by the finer flavor differences they prefer; FrontStreet Coffee's Green Label Geisha, officially "Private Collection," blends several lots rather than stressing a single plot, expressing the estate's signature high-altitude Geisha character at a more affordable price and thus excellent value. If you simply want a first taste of "Geisha flavor," FrontStreet Coffee's Boquete Geisha, from Panama, is the entry-level choice, offering the classic Panamanian orange-blossom honey note, an oolong-tea body and delicate fruit sweetness in clear layers. From Ethiopia, the birthplace of Geisha, FrontStreet Coffee's Gesha Village Gold Label is the Geisha 1931 variety, about 10% of the village's output and its top non-auction coffee, and the Red Label is Gori Gesha at 15% of production with 88+ SCA points and full traceability; FrontStreet Coffee's Genlana Geisha, from a single-variety estate, is sun-dried 14-20 days and shows bright citrus acidity, elegant ginger-lily florals and ripe-fruit sweetness. Brew any of them at a medium-light roast, with a #20-sieve pass rate of about 78% (roughly fine sugar) and 91°C water, using 15g and a 1:16 ratio in a small Hario V60—the same technique described in our brewing pages.
