Catimor Coffee

Catimor exists because of a race against a fungus. Coffee leaf rust, Hemileia vastatrix, had already wrecked plantations across Africa and Asia by the 1950s, and researchers at Portugal’s Centro de Investigacao das Ferrugens do Cafeeiro (CIFC) in Oeiras knew the Americas were next. Their raw material was Hibrido de Timor, a natural Arabica-Robusta cross discovered growing spontaneously on the island of Timor in 1927, whose Robusta ancestry carried real rust immunity. CIFC received Timor Hybrid seed in 1958, and in 1967 crossed two rust-resistant selections (CIFC 832/1 and 832/2) with Red Caturra, itself a compact Bourbon mutation out of Brazil. The resulting lines, HW26 and H46, reached Brazil’s Instituto Agronomico in 1970, the same year leaf rust reached Brazil itself, and were named Catimor: Caturra plus Timor.

What shipped out of CIFC afterward was never one plant but a breeding template. Costa Rica’s CATIE research station received fifth-generation Catimor progeny in 1978 and produced Costa Rica 95; Honduras selected its own line into Lempira; El Salvador’s version became Catisic; Colombia ran a parallel program through Cenicafe. Honduras separately selected a different CATIE line, T5175, into IHCAFE 90. World Coffee Research’s own profiles rate these lines differently on cup potential, one rating a specific line’s high-altitude quality “Very Low,” which is the real answer to why Catimor has a reputation problem: it was never a single variety with one flavor ceiling, and some selections were bred for yield and rust resistance with cup quality as an afterthought.

That reputation runs deep. Coffee Review’s own tasting notes, in a section titled “The Cup-Suspect Varieties,” call Catimor “particularly neutral in the cup.” Yet Coffea Guatemala’s Chich’upao, grown from Costa Rica 90, Parainema, and Sarchimor trees, scored 93 points and landed at No. 14 on Coffee Review’s Top 30 Coffees of 2024. The flatness has a documented mechanism, too: Torch Coffee Labs reports that Catimor carries naturally higher chlorogenic acid, the compound behind astringency, and that fermentation breaks it down. In a blind cupping of six Q Graders, a carefully processed Guatemalan Catimor from producer Nilton Perez scored second-highest of the lineup, praised for its sweetness and syrup-like aftertaste, and still sold for less than his Bourbon simply because buyers would not pay Bourbon prices for a coffee named Catimor.

Today Catimor and its country-specific offshoots are the backbone of Vietnam’s arabica production, common across Central America, and increasingly grown in China’s Yunnan province, valued everywhere for the same reason CIFC bred it: it fruits within two years, tolerates dense planting, and shrugs off the rust that can wipe out a Typica or Bourbon field in a season. That trade-off, yield and disease resistance now, cup quality only with real effort, is the whole story behind the name.
