Story

Our first Ethiopian release of the season, we’re glad to welcome back an old favourite from years past with this filter roast from Nano Challa.

The Producers

Near to Agaro in the Genji Challa woreda of Ethiopia’s Oromia zone some 600 smallhold coffee farmers deliver their cherry for processing at the Nano Challa wet mill. Each farmer will on average have a small parcel of land, around 0.5 hectares on average, with 3 hectares being deemed a large farm. They are tending to native landrace varieties, of which some have been identified and catalogued by JARC, the Jimma Agricultural Research Centre, such as 74110 and 74112. They are working organically at altitudes between 1,900 and 2,200 metres.  

Historically farmers in the region would collect and sun-dry their own coffee, producing lower grade naturals which would be for a very cheap price. Since working with Nano Challa and the infrastructures set in place by the Technoserve initiative, farmers have been able to access a more discerning market and receive premium payments for their crop, enabling them to upgrade their homes and diversify their income through starting other businesses. 

The Washing Station

First established in 2009, the Nano Challa wet mill was initially built and financed by Technoserve, who subsequently set up others in the region such as Duromina and Yukro washing stations. The potential to produce high quality coffee was always there but building these mills as well as providing agricultural and economic advice has empowered the region and these washing stations have become very renowned and respected by roasters around the world. 

Since the beginning they have used a Penagos eco-pulper and given their success story they have bought multiple more eco-pulpers as well as establishing another wet mill in 2018 to manage their growing volumes. They use a vetiver reed bed to treat wastewater from processing which acts as a natural filter. Initially tied to the Oromia Cooperative Union they are now part of the Kata Muduga Multi-purpose Farmers’ Cooperative Union, which was established in 2016.

More on Pre-Ground

From finest to coarsest, the filter grind settings we are offering are as follows:

  • Fairly Fine (1 Cup Pourover/AeroPress/SteepShot)
  • Fine-Medium (2 Cup Pourover/Clever Dripper)
  • Medium (French Press)
  • Coarse (Moccamaster/Autobrewer/Chemex)
  • Our pre-ground options are designed to map to a particular dose of coffee as much as the brewers mentioned. If you’re brewing just 15g in a 2 Cup V60 brew cone as it is the only cone you have, you should opt for the 1 Cup V60 grind size. Similarly, if you are just brewing 30g in a MoccaMaster, you should opt for a finer grind setting, like the 2 Cup V60.

    We would advise using these as starting points:
  • 12-18g: Fairly fine
  • 19-28g: Fine-medium
  • 29-55g: Medium
  • 56-80g: Coarse
  • Please note that pre-ground coffee will be delivered in a different bag to its whole bean counterpart. This is to ensure easy access when it comes to measuring our your dose. You will also find a ‘Ground on’ date on the bag in place of a ‘Roasted on’ date – we advise brewing your pre-ground coffee within 2 weeks of the ‘Ground on’ date.
