summary

Tracon’s reputation is well regarded and are no strangers among COE members globally. In 2021, Tracon chose to participate in Ethiopia’s second ever Cup of Excellence Auction and had 2 different coffees score an impressive placement in the top 20 of all the coffees submitted in the Ethiopia COE Auction. In 2021, a record-breaking number of entries 1,849 for any countrywide Cup of Excellence competition entered the competition to compete that particular year. Placing in the best of top 20 coffees produced in Ethiopia should speak volumes for itself..

This is our fourth year sourcing and working with Tracon Trading. From our experience over the years of consistently sourcing from local Kebeles (villages) in and around Gedeb, Worka Sakaro & Chelbessa in particular, the coffees grown in these areas are nothing short of absolute bangers and are highly coveted around the world for their very high quality and unique flavor profiles. Add careful antiquated experimental processing to the mix and a very methodical approach to dry milling, you might have lightening in a bottle.

Tracon is a family owned business who owns a total of 30 washing stations located around Ethiopia. All experimental coffees are processed at Tracon’s own washing stations. First, local farmers and brokers who collect cherries from the surrounding villages of Worka Sakaro & Worka Chelbessa come to deliver their cherries to Tracon’s Banko Gotiti Washing Station. The Banko Gotiti Washing Station is managed by Ali Yasin. Ali oversees and manages these experimental projects for Tracon at Banko Gotiti. His day to day during harvest is loaded with providing oversight of cherry selection, post harvest production and compensation distribution directly to their local farming partners. The Banko Gotiti Washing Station happens to also be the second largest washing station in the Tracon network of washing stations they own. Over the years, proceeds raised from Banko Gotiti have been reinvested into the local community by investing in several local area school projects, water drilling projects and has also trained many locals in the nearby communities different forms of fermentation techniques with free expert led workshops.

Tracon has developed a state of the art modern coffee cleaning and milling facility in Addis Ababa where the coffees are all transferred for final milling following the initial collection and post harvest production phase of all their coffee. The facilty is equipped with the latest Pinhalese coffee processing equipment to sort coffees by density, size and also utilize high level pieces of automated equipment like optical color sorters for final sorting. Each lot contracted with Tracon this year was done on a prebook basis prior to the coffee harvest. We believe embracing this model equips partners with the tools and resources to provide early harvest premium payments directly to farmers and to help producers mitigate and calculate risk knowing they have a secured buying partner on the other end to support their efforts.

PROCESSING

Once the cherries arrive to Tracon’s Banko Gotiti Washing Station, they are submerged in clean water to wash out any possible dirt or contamination that could disrupt the development of lactobacillus cultures during fermentation (the same bacteria mainly used in the development of fermented dairy, sourdough, vegetable foods or used as probiotics). Once all cherries are clean and classified by their density, the heaviest cherries and cherries recorded with the highest sugar content measured by BRIX are selected and placed inside the fermentation tanks. These tanks were modified to have a one way relief valve added to the top of the tanks along with a hose that is placed inside a water bottle outside of the tank. The hose is placed inside the water bottle allowing the water to act as a barrier so that no oxygen can enter inside the tank and only allowing gasses to exit the tank, creating an environment free of oxygen within the tanks. The process is methodically controlled by checking pH levels, temperature, and oxygen levels to create the perfect environment and conditions for the lactobacillus to strive during this stage of fermentation. The Lactobacillus during fermentation multiply rapidly in the fermentation matrix, by taking up nutrients from the surrounding environment, and cause rapid acidification in the fermenting system via the production of organic compounds that convert fermentable sugars from the cherries into mainly lactic acid resulting in an enhanced characteristics of the coffee. After fermenting in the tanks for 96 hours, the coffee is then transferred to complete drying on raised drying beds for 20 days where the coffees are routinely raked and rotated by hand to assure consistent exposure and uniform drying during the drying phase.

JARC VARIETIES - 1974/1975 CBD RESITANT SELECTIONS

Currently the majority of coffee produced in Ethiopia is produced from three production systems: forest, semi-forest, and garden coffee. The level of variation among coffee varieties in the forest and semi-forest production systems are recognized as a higher degree of quality than garden coffee production systems. Farmers in Ethiopia have always had an interest in changing the genetic base of their varieties in different production systems in pursuit to improve coffee production and yield. The Jimma Agricultural Research Center (JARC) has made huge contributions to the global coffee community with its efforts over the past 40 years to expand knowledge through scientific research and studies in Ethiopia. In the efforts by the (JARC) to push towards revolutionizing the development of modern coffee varieties in Ethiopia they have created innovative methods to genetically combat CBD (coffee berry disease) and increase the overall efficiency in production and yield for coffees grown naturally in the forest and semi-forest production systems.

In 1971, coffee berry disease (CBD) was spreading throughout Ethiopia and likely had been around for years. Initial trials in 1972 used chemical-based fungicides to test prevention of the disease. While these proved successful, it was decided that a better solution would be to collect and use the broad genetic diversity of Ethiopian coffee to develop CBD-resistant varieties. The selection process for these varieties began in 1973 and resulted in collections from 19 locations in Southwestern Ethiopia. After collecting seeds from 639 different coffee trees originally collected in the areas of Gera, Metu-Bishari, Washi and Wush Wush for showing resistance against CBD. For 1974 and 1975 CBD resistant improved coffee varieties, if a variety name starts either with a 74 or 75 it is a selection number given to the variety and can represent a broader group of different varieties that stem from the 1974 and 1975 CBD Resistant Selection Group.


Gera Selection: 75227, 741

Metu-Bishari: 74165, 74158, 74112, 74148, 74140

Washi: 7487, 7454, 7440, 744

Wush Wush: 754

Variety Gibirinna 74110 & Serto 74112

The level of variation among coffee varieties in the forest and semi-forest production systems are recognized as a higher degree of quality than garden coffee production systems. The 74112 variety begins with “74” to indicate the official cataloging and selection in 1974. Variety 74112 originates in the Metu-Bishari forest and was released in 1979 from it's counterpart 74110 for its disease resistance and yield potential. The trees are smaller in stature and compact.

REGIONAL INFORMATION

Gedeb, Gedeo Zone

Yirgacheffe is famous for putting washed coffee on the map in Ethiopia decades ago. People fell in love with the floral and citric profiles that the washing process brought out in coffees of Yirgacheffe, and almost instantly this small town became famous. The region is home to 400 + smallholder regional coffee cherry producers.

Southern Ethiopia, and Yirgacheffe in particular can get very confusing when figuring out the geographical areas and names. Yirgacheffe is actually the name of a small town, AND the name of a small wordea (district). However, the name Yirgacheffe became synonymous for coffees coming from a much greater area than just the town or the woreda. Today, Yirgacheffee coffee is mostly from the political boundary area called the Gedeo Zone (named after the Gedeo ethic group). Notably though, a very small amount of coffee labeled as Yirgacheffe comes from the Oromia SNNPR region that borders the western edge of Gedeo. The Gedeo Zone is broken down into 7 woredas, those are; Dilla, Dilla Zuria, Bule, Wenago, Yirgacheffe, Kochere and Gedeb.

Gedeb is the southern most woreda (district) of the Gedeo Zone, and in comparison to other areas coffee is somewhat newer to this area. Many farms here have only been growing coffee for 1 or 2 generations, and much of the coffee is only 20-30 years old. Farms in this area tend to be slightly larger than in the northern part of Yirgacheffe, but are still relatively small- averaging around 1-2 hectares, however some larger farms that are 5-20 hectares do exist.

The Gedeb woreda is home to the coffee producing kebeles (communities) Worka Chelbessa, Worka Sakaro, Banko Dhadhato, Halo Hartume, Harmufo, Gedeb Gubita, Gedeb Galcha, Banko Chelchele, and Banko Gotiti. Fairly recently, the political boundaries of Gedeb grew to include communities north of Gedeb, that were formally a part of Kochere. Those communities are: Mora Layo, Mora, Bisha, Geshe Jeba, Abel, Kedida Gubeta, and Gora Dibandi. These kebeles do not produce a lot of coffee due to their extreme elevation often over 2400 meters.
