Where Do Ethiopian Coffee Varieties Like 74110 and 74158 Come From?

Ethiopian coffee varieties fall into three cultivation models: wild forest coffee in the southwest, garden coffee planted beside farmers' homes in lots of a few hundred trees, and large estates with clear archival records and standardized field management. The numeric codes such as 74110 and 74158 trace back to the JARC disease-resistant breeding program of the 1970s.

Forest coffee trees result from natural mixing among many varieties, so their yields are usually lower than those of selected elite varieties. Lots like the Kafa Forest washed coffee come from that system, with nearby farmers picking cherries and delivering them to processing stations. Garden coffee is the main livelihood for most smallholders, and tree sources vary widely, from inherited plants to seeds brought in from other regions.

Ethiopia, as the birthplace of coffee, has a variety system far more complex than we might imagine. What exactly does the commonly seen "Heirloom" native variety mean on the market? What do the numeric codes such as 74110 and 74158 that have frequently appeared on packaging in recent years represent? This article will sort out the three cultivation models of Ethiopian coffee, trace the historical context of the JARC disease-resistant breeding program in the 1970s, explain the naming logic of the 74/75 series strains, and introduce the progress in identifying and naming Landrace local varieties. At the same time, by combining specific products such as Front Street Coffee's Kafa Forest washed lot and Sidamo Santa Vini 74158, it will help readers build a complete understanding of Ethiopia's variety system.

Coffee cultivation in Ethiopia can generally be grouped into three forms. The first is wild forest coffee. These coffee trees are mainly distributed in the southwestern part of the country. Because they are themselves the result of natural mixing among multiple varieties, their reproductive capacity and output levels are usually inferior to those of artificially selected elite varieties.

Take Kafa Forest from the "Front Street" bean list as an example. It comes precisely from this forest cultivation system. During the coffee fruit ripening season, nearby farmers go into the forest to pick the cherries, then transport the fresh fruit to nearby processing stations for washing or natural processing. The lot Front Street has listed this time uses the more stable washed process, combined with a light-to-medium roast, to preserve as much floral aroma and fruity acidity as possible.

The second is garden cultivation. The coffee trees are planted beside farmers' homes, with each household managing about a few hundred trees. The fruit is picked as soon as it ripens. This is the main way most small-scale coffee farmers make a living. The sources of these coffee trees are quite diverse: they may have been left behind by a previous landlord, obtained through exchanges between neighbors, or grown from seeds introduced from other producing regions. The third is large coffee farms or estates. These growers own contiguous tracts of land, the varieties planted have clear archival records, and field management follows standardized procedures. The best-known representative among them is Gesha Village Estate.

A considerable portion of the Ethiopian coffee currently circulating in the market comes from cooperative unions. Cooperatives gather coffee cherries harvested by farmers in a certain area, process them uniformly, and then sell them externally. It is estimated that there are currently about 10,000 to 15,000 coffee varieties in Ethiopia, and most of them have not yet undergone formal genetic identification. For this reason, Heirloom does not refer to one specific variety. It is more like a producing-region-level concept of blended green beans—cooperatives pool together the harvests of many smallholders from the same period and combine them. The diversity of variety sources is also directly reflected in appearance: these coffee beans vary in screen size, dimensions, and shape, with some large and some small, some long and some round. It can be understood as a "blended-style lot."

When buying Ethiopian coffee beans in daily life, the variety column on the packaging is mostly labeled "Heirloom," often translated into Chinese as native variety or heirloom, referring precisely to this mixed-harvest coffee variety. However, in recent years, numeric codes have begun to appear in the variety information of many Ethiopian beans, such as 74110, 74112, 74158, and so on. What exactly do they mean?

In the 1970s, coffee plants in many Ethiopian producing regions were severely attacked by Coffee Berry Disease (CBD). Infected coffee cherries gradually turned from green to gray-black and eventually died on the branches. Once a coffee tree is infected, crop losses can reach around 80%.

In 1972, growers began trying to use chemical fungicides to prevent and control CBD. Although some results were achieved, continuous spraying of pesticides was ultimately only a stopgap measure. The long-term solution was to select varieties with naturally high resistance. The following year, the Ethiopian coffee research institution JARC (Jimma Agricultural Research Center) identified 19 collection sites in the southwest to carry out variety collection work. By 1975, researchers had collected a total of 639 seed samples. After scientific identification and field trials, they finally selected 13 coffee varieties that were resistant to CBD, drought-tolerant, high-yielding, and excellent in flavor performance.

The 74*** and 75*** series that appeared afterward were bred and improved from this group of mother trees. JARC recorded this broad category as "1974/1975 CBD-Resistant Selections." Therefore, 74 indicates that the variety was cataloged in 1974, and the following three digits are the test sample number. The 74 series varieties we often hear about were all cataloged during this period. For example, the Sidamo Santa Vini coffee beans on Front Street's bean list use precisely the numeric variety 74158. After ripe cherries undergo 96 hours of fermentation and natural processing, they present intense pink floral notes as well as tropical fruit flavors such as guava and pineapple.

Perhaps some attentive friends have also noticed that, in addition to numeric varieties, some Ethiopian coffees also use English names we are less familiar with. What is the relationship between these varieties and native varieties?

In fact, coffee trees growing in the field differ somewhat from one another in traits. Some plants show strong cultivation advantages. They not only adapt to the local soil, climate, and environmental conditions, but their flavor also gradually becomes stable. At the same time, they also possess disease resistance and high yield, and are therefore deliberately retained by farmers. After years of cultivation and hybridization, they have gradually become "domesticated," and with farmers' conscious selection, the traits of some plants are no longer difficult to predict and have become stable and regular. This type of variety is called Landrace in the industry, meaning "local variety."

In recent years, promoted by the Ethiopian agricultural research institution JARC (Jimma Agricultural Research Center), many regional local varieties formerly broadly classified under Heirloom have been identified one by one and given names, such as Kurume, Wolishao, Dega, Choche, Sardo Buna, Bedessa, and others. At the same time, more and more international green bean traders, in order to satisfy consumer demand for "uniqueness," tend to purchase local varieties that can reflect the characteristics of the producing region. From the cultivation side, these local varieties show good adaptability locally and can also ensure that farmers obtain decent returns, so both new and old coffee farmers are naturally more willing to grow them.
