Kenya Gachatha OT-18
Gachatha Farmers Cooperative Society is made up of about 1150 farmers. Jane Nyawira has managed their wet mill (factory) for over 12 years now. It is rare to see a manager work for such a long time and shows that dedication and consistency always help provide a great cup. Located 100 miles north of Nairobi, the cooperative is in the famous coffee growing region of Nyeri. There they utilize the elevation of the Aberdare mountains and water from the Kangunu river. This station has consistently produced incredibly sweet, complex bright coffees and we continue to ask marketers and reps to bid on these at the auction on our behalf.
Kenya has a pretty advanced coffee system. Two avenues are used to sell and export most coffee: the Nairobi Coffee Exchange (central auction system) and a direct-sale system with a marketer. Cooperatives tend to lean towards the first and use the auction system to sell their coffees based on quality. You must be a licensed marketer to buy coffee through the competitive auction system by bidding on coffees. Auctions are held every Tuesday with samples of the coffees going out to the marketers and cuppers the week prior. This way you can cup the outturns for the week and decide which coffees you wish to bid on. An outturn refers to the week of wet milling and production of coffee. You’ll see a number next to all our Kenya lots which describe which outturn it was. We tend to like outturns between 14-21, which are in the middle to the end of harvest time and usually have the most nutrient dense and best-tasting coffees.
This year coffee production was down about 25% in Kenya. This means the auction system for the coffees that cupped higher reached almost unprecedented levels. While this does mean our Kenyans will be a bit more expensive this year, it also meant less competition for us. And we were able to purchase quite a few more lots than we normally do. This is our personal best year of sourcing in Kenya. We are really excited to release some special lots all year long.
In the Kenya process, first the cherries are sorted, and under-ripe/overripe cherries are removed. Once the sorting is finished the coffee is then depulped. This is done by squeezing the cherry through a screen and removing the fruit and skin from the bean. The coffee is then left to ferment in white ceramic tiled tanks for 24 hours. Next, the coffee is stirred for a short amount of time and left to ferment for another 24 hours. After two days of dry fermentation, the coffee is washed with fresh water, removing the sticky mucilage attached to the beans that are loosened by bacteria during the fermentation. It’s then soaked in water to ferment overnight slightly. The coffee goes through sorting and density channels which separates the lots, and then it is taken to raised beds to dry. Once it reaches 11.5-12% moisture content, the coffee is brought to conditioning bins to rest until it goes to the dry mill.
Once a coffee has been processed, dried and then milled it goes to a sorter that separates the beans by specific characteristics, mainly size. Coffee goes into a machine that vibrates sending beans through different screens with certain size holes and sorts the coffee based on size and density. This results in a more uniform coffee and cup profile. Then the coffees are auctioned based on the grade (size & density) they have.
AA (screen size 17 & 18)
The largest and most celebrated grade of Kenyan coffee. Usually the highest priced coffee on the auction from each outturn and factory. AA is is the most common grade we buy and what we normally expect from an outstanding Kenya cup.
AB (screen size 15 & 16 )
This grade represents about 30% of Kenya production. While AB is usually considered lower quality than AA, we find that to not be accurate in the cup. Over the years of cupping, we have consistently found incredible AB’s that actually cup better than their more prestigious AA relatives, enforcing the idea that everything must be cupped and not have its value determined based on classification or reputation.
Peaberries represents about 10% of Kenya production. They are a result of a coffee cherry only producing one bean instead of two. Technically they are fused together during early stages and form one round bean instead of two half spheres. We tend to notice more fermentation tasting notes here. Winey, syrupy, and mouth coating are some of the attributes that we usually notice in the cup.
E (large Peaberries & large chipped beans)
C (screen size 14 & 15)
TT (falls through 14)
T (small or broken pieces of beans)
FILTER – V60
25g Coffee : 400g Water 205°F

A fresh run of Kenyan coffee offerings is underway! This Gachatha OT-18 is juicy white grape and unique tamarind. Look for a little sweet sugarcane when dialing in to tie all of the bright fruit notes together. We liked the V60 because it brought out the fruit notes and made each one stand out. If under-extracted this coffee tasted tart and sour. If over-extracted the acidity is too mellow and brings out a bitter aftertaste. Look for distinct fruitiness and sugarcane to shine through a balanced cup.

This Gachatha OT-18 has a unique citrus acidity that reminds us of tamarind. It’s tart but sweet and mellows out as you drink it. White grape and peach appear alongside it, and there is a botanical sweetness of sugarcane throughout. This was a very bright espresso as you would expect from a Kenyan coffee. Not for the faint of heart, we can see it as a little aggressive for the new espresso connoisseur. Careful of under-extraction because the acidity will be very tart and sour. Over-extraction loses some of the punch of the acidity and sweetness. We don’t recommend most milk drinks with it. The acidity doesn’t carry through above a cappuccino very well. But, it does make a tasty cortado!
This is a Relationship Coffee that we purchased this coffee through our friends at Dormans Coffee in Nairobi. They took our offer to Gachatha Factory of $5.20 per pound, which they accepted. Dormans takes a small fee for negotiating the price as per registered Kenya Coffee Marketing. We paid $5.50 per pound total FOB and cupped the coffee at an 88.25. We also partnered with our long-time friends, Ally Coffee to bring the coffee stateside and paid an additional .40¢ per pound of logistics to move the coffee to the states. This was by far the smoothest contract that we have had in Kenya to date. Raphael (Dormans) and Michael (Ally) were extremely helpful in getting the coffee moving quickly during a tumultuous time in Kenya.
- The Coffee Commodity purchase price was $1.18/lb when we purchased this coffee.
- The Fair Trade Coffee minimum price was $1.60/lb when we purchased this coffee.
* We as a company believe transparency is unbelievably important. However, we decided only to list what is shown here because we don’t know where to stop. Do we list the amount of coffee lost in roasting due to moisture loss? Should we list our roaster Mark's salary? The warehouse rent? The utilities? The point of listing things above is not to justify what we charge or what we profit, but to give a realistic snapshot of the industry and how Specialty Coffee can be different than other commodity industries. If you have concerns feel free to email us and I’ll write you back when I’m available.
Relationship Coffee is an initiative we, at Onyx, have purposely created to describe our sourcing and buying practices and how we document them. Certifications like Direct Trade, Fair Trade, and others have impacted the coffee communities in mostly positive ways but also in some negative ways. We find that blanket terms and applying them to a multitude of business models no longer describes what we do.
In reality, every company is different, and we wanted to step out from the mold and create a new set of standards that exceeds in every department from quality to transparency to pricing. The growers, exporters, importers, associations, cooperatives, and other entities are always a set of relationships. To be honest, many are our friends as much as they are our producers and partners. We share information, family news, meals, housing, many faiths, and argue politics. Oh, and we love it. Relationship Coffee for Onyx is the mark of an honest exchange ethos that permeates our company, and we hope it encourages the growth of specialty coffee for the future.
We visited the farm or cupping lab and listened to the producer/agronomist or head cooperative/association to ascertain better knowledge about the culture and practices.
We cupped the coffee, and it scored to our industry-high standards.
We do not buy futures or multiple harvests to ensure that what we cupped for that year is what we serve.
We do not ask for exclusivity from producers, binding their options.
We pay what the coffee is worth. This always is at least double Fair Trade minimum due to the quality we buy, and many times is three to ten times the amount.
We do not finance any coffee. Cash flow is just as important as final price. Coffee is paid in full upon delivery, and we pay a percentage up front upon contracting.
We are completely transparent from price to logistics to cupping score, to who we work with buying and shipping coffee.
We work to set premiums after a contracted price to incentivize quality and community building. This can be .10¢ - .25¢ extra per pound or community projects such as school supplies in the growing village, sports jerseys, vented chimneys for kitchen fires, etc.
