Kenya Kiunyu OT-18

Save 16%

Look for notes of blackberry, brown sugar, peach and black tea. 

Our fresh crop Kenya auctions have arrived! Kiunyu is the first release from the eight lots we purchased this year in Nairobi. We start with this arrogant, showy coffee from the Karithathi Cooperative. The Kiunyu AA tastes of brown sugar, vibrant blackberries, and fresh peach with a tactile of a juicy nectar. We really like bright and light Kenya coffees in the late summer heat.



Kiunyu is the first of two wet mills (factories) owned by the Karithathi Farmers Cooperative Society located in Kianyaga. The cooperative is mostly made of small-hold farmers with around 1200 current members. We cupped this lot at the Dormans Coffee cupping lab in Kenya this February and right away it jumped off the table. Incredible ripe fruits and complex sugars were apparent immediately. Pursuing this coffee during the Auction was an obvious choice. Now that the coffee has landed at the roastery, it cups exactly as we remember and validates all our anticipated excitement.



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.


PB (Peaberry)

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 – Stagg [X] Dripper
20g Coffee : 350g Water 205°F
~2:35 Drain Time

The Kiunyu is one of the sweetest coffees we’ve ever tasted. Blackberry and peach with brown sugar sweetness throughout and a pleasant black tea finish. We really liked the sweetness and clarity that the Stagg [X] Dripper from Fellow Products brought out. If under-extracted it's very tart and one-sided. If over-extracted it's like a bitter blackberry and dry black tea.
