Why does the term "Ethiopian Heirloom" hinder the progress of specialty coffee?

5/22/2025

0 Comments

 
The term "Ethiopian Heirloom" is often considered a catch-all term for Ethiopia's diverse coffee varieties, evoking a sense of tradition and mysticism. However, we have argued for several years that its continued use obscures transparency, undermines traceability, and limits the specialty coffee industry's ability to fully appreciate Ethiopia's genetic diversity.
Picture
​Proponents of the term "Ethiopian Heirloom" claim that it reflects the complex and indigenous nature of Ethiopian coffee varieties. However, this broad term risks oversimplifying a rich genetic landscape. Ethiopia, the birthplace of coffee, is home to between 6,000 and 10,000 distinct varieties, many of which have been studied and catalogued, such as JARC varieties (e.g., 74110, 74112) or regional landraces like Kurume and Dega. Labelling them as "Heirloom" blurs crucial distinctions in flavour, yield, and disease resistance that roasters and farmers need to make informed decisions.

HOW DOES THE BOURBON VARIETY GET TO RWANDA?

12/17/2022

0 Comments

 
Today in the world of specialty coffee, Bourbon and Typica are the most important Arabica coffee varieties. Recent genetic studies have confirmed that Bourbon and Typica were the seeds brought from Ethiopia to Yemen, and from the latter they spread throughout the world, forming the basis of modern Arabica coffee cultivation.
Picture
​It was the French who attempted to introduce coffee three times from Yemen to Bourbon Island (now La Réunion), in 1708, 1715 and 1718. Genetic studies have confirmed that only a small number of plants from the second introduction and some from the third introduction they were successful. Until the middle of the 19th century, Bourbon coffee did not leave the island.

WHY KENYAN FARMERS ARE GRAFTING RUIRU 11 WITH SL 28?

5/24/2022

12 Comments

 
Grafting is a horticultural technique whereby plant tissues are joined together to continue growing together. The upper part of the combined plant is called the stem, while the lower part is called the rootstock.
Picture
​The Ruiru 11 variety was released in 1985. The name of the variety has the prefix "Ruiru" which refers to the location of the Kenya Coffee Research Station where the variety was developed. The variety is not only resistant to CBD and CLR, but is also compact, allowing farmers to intensify production per unit of land.

WHAT DOES "HEIRLOOM" MEANS?

4/2/2019

0 Comments

 
According to the Cambridge dictionary, the word "Heirloom" has the following meanings:

1.- valuable object that older members of a family have given to younger members of the same family for many years.
2.- a fruit, plant or seed of a type, which has existed for many years.
Picture
From a botanical point of view, the definition of an heirloom variety establishes that this must be open-pollinated. Arabica coffee is a self-pollinated crop, so from the very beginning the definition of heirloom doesn’t apply to Arabica coffee.

UNKNOWN HEROES OF THE GENETIC DIVERSITY OF ARABICAS

1/16/2019

0 Comments

 
Kenya is probably one of the most advanced producing countries, in the study and experimentation with the genetic diversity of Arabicas, and is far ahead of important countries such as Ethiopia for example.
Picture
​On our last trip to Kenya we met the great "Dr. James", who works at the "Kenya Coffee Research Institute" station in Nyeri. In this place, he explained, how they are performing grafting of Ruiru 11 with SL 28, and the importance of its result for the future of the industry.
