Nearly every cup of specialty Arabica you drink today traces back to one of two trees. Almost everything else on a bag's label, Caturra, Mundo Novo, SL28, Pacamara, and dozens more, is either a natural mutation, a natural cross, or a deliberate breeding project built on one or both of two lineages: Typica and Bourbon. Both trace back to Yemen, and both left there carrying the same genetic inheritance from wild Ethiopian Arabica, but they took different routes out and ended up looking and tasting distinct enough to found two separate branches of the family tree.[1][2]
Typica: the first to leave Yemen
Typica's documented path starts in Yemen in the 15th or 16th century. By around 1700, Yemeni seed was already being grown on India's Malabar coast, and in 1696 and 1699 seeds from Malabar were sent on to Batavia, in Java, where the plants that grew from them became what's recognized today as the distinct Typica variety.[1] From Java, a single plant reached the botanical gardens in Amsterdam in 1706, and a cutting was shared with France in 1714. Dutch and French colonial shipping routes carried it onward from there: to Suriname and French Guiana by the 1720s, to Martinique in 1723, Jamaica in 1730, and Santo Domingo in 1735, then on to Cuba by 1748 and into Central America by the late 1700s.[1] Typica dominated South and Central American coffee farms until roughly the 1940s, and it's still grown today in Peru, the Dominican Republic, and Jamaica, where it's sold under the name Jamaica Blue Mountain.[1] The tree is tall and slow to bear fruit, with a notably low yield, but it's long been valued for a clean, sweet, well-balanced cup. Its biggest practical weakness is a very high susceptibility to coffee leaf rust.[1]
Bourbon: the French island detour
Bourbon followed a separate route out of Yemen. French missionaries carried it to Bourbon Island, now called Réunion, in the early 1700s, and the variety kept the island's old name.[2] It stayed there for more than a century before missionaries began carrying it onward from the mid-1800s, reaching Brazil by around 1860 and spreading from there through South and Central America and into Africa. In Latin America, it mixed with other Bourbon-related stock that had arrived separately from India, and in parts of Africa with local Ethiopian landraces, so today's Bourbon-descended trees aren't genetically identical across regions.[2] Bourbon has been largely replaced on Latin American farms by its own descendants, but it's still grown directly in El Salvador, Guatemala, Honduras, and Peru. Like Typica, the tree is tall, and it shares a similarly high susceptibility to coffee leaf rust, but at high altitude its cup quality potential is rated exceptional, one reason it has held on in specialty circles even as its yield-focused descendants took over commercial farms.[2]
How two trees became an entire family
The reason Typica and Bourbon matter beyond history is that almost every other named variety in specialty coffee is their direct offspring, through mutation or cross. Caturra is a natural dwarf mutation of Bourbon, discovered on a farm in Minas Gerais, Brazil, sometime between 1915 and 1918; a single gene change produced a smaller, more closely branched plant that could be planted far more densely, and Brazil's Instituto Agronômico began formal selection on it in 1937.[3] Mundo Novo arose differently: a natural cross between Bourbon and Typica, found in São Paulo state in 1943 and distributed to Brazilian farmers starting in 1952, combining Typica's cup quality with a taller, more vigorous and productive plant.[4] In Kenya, breeders at the colonial-era Scott Agricultural Laboratories selected SL28 in 1935 from a single tree within a population called Tanganyika Drought Resistant, found in what's now Tanzania in 1931; genetic testing has since confirmed SL28's Bourbon-related background, and it's now considered one of the most celebrated varieties in Africa, with some of the original Kenyan trees still producing fruit after 60 to 80 years.[5]
Two more mutations, one from each parent lineage, eventually met again. Pacas is a natural dwarf mutation of Bourbon found on a family farm in El Salvador's Santa Ana region in 1949, and Maragogipe is a natural mutation of Typica discovered near the Brazilian city of the same name in 1870, prized for producing unusually large beans.[6][7] When El Salvador's coffee research institute crossed Pacas with Maragogipe, the result was Pacamara, a variety capable of exceptional cup quality that now regularly dominates El Salvador's Cup of Excellence competitions.[8] In a single variety, Pacamara carries genetic material from both of coffee's founding trees.
What this means for the cup in front of you
Indonesia has its own direct stake in this family tree. The Java plantings of 1696 and 1699 are the ones that produced the first true Typica trees, and much of the Arabica grown in Indonesia since has descended from, or been planted alongside, that same Typica line.[1] None of this makes Typica or Bourbon better than their more productive descendants. It does mean that when a roaster names a variety on a bag, including on Cup Taste's own bags, they're pointing to one small branch of a family tree that still only has two roots, both of them trees planted more than 250 years ago.
