Genji Challa Filter

Genji Challa is a wet mill that is part of the Nano Challa cooperative in the town of Gera, Agaro. It is only 3 km from the Nano Challa cooperative, and between them, they have increased the number of farmers to over 600 members this year. The doubling of the wet mills allows the cooperative to better serve members by increasing its capacity and outreach. Access to these stations has allowed farmers to choose between natural and washed processing, expanding their opportunities in the global specialty coffee market.

The cherries are sourced from the surrounding kebeles (neighbourhoods) and the lots are named after the kebeles in which the coffee is grown. The cherries delivered to the station are a combination of Gibirinna 74110 and Serto 74112. Both are from the Metu Bishari selections made in the forest of the same name in the Illubabur area by the Jimma Agricultural Research Centre (JARC) in 1974. They were specifically selected for their resistance to coffee berry disease.

Genji Challa is equipped with a Penagos 5000 ecopulper and, once the coffee is washed, it is transferred to a drying table where it rests for a single day before being transferred to raised beds to finish drying in the sun over an average of 10 days. Both stations are at an altitude of just under 1,900 metres, and the farm members grow coffee at 2,000 metres above sea level.
The cooperative was formed as part of an initiative to help farmers in a more general way. The programme was administered by a non-governmental organisation that not only coordinates agronomists and managers for each of the cooperatives it works with, but also has a business advisor assigned to help the cooperative manage its debt, reinvest in quality improvements in the mill, and verify the distribution of income to all members. They have since "graduated" from this programme and are now part of the Kata Maduga Union that assists the cooperatives in functions such as marketing, exporting and general international representation.

Brew Guide

Grind Size

Grind size is important and varies from grinder to grinder. Below we suggest a rating from 1 to 10. 1 = extremely fine, too fine. 10 = very coarse, too coarse.

Pour-Over with Filter (V60/Chemex)

Coffee Grind 6-7

We use 15 grams of coffee with 250 grams of 95 degree water.

Wet the filter with hot water and discard the water.

Pour 40 grams of water onto the coffee to bloom and give the brewer a gentle swirl, wait 30 seconds

Add another 40 grams of water and give it another gentle swirl, wait 30

Slowly add 85 grams more water and give another gentle swirl

Finally slowly add the remainder water and give a final gentle swirl

The water should filter through and have a flat base of coffee with only
fines stuck to the upper filter wall.

Aeropress (non inverted)

Coffee Grind 5-6

We use 15 grams of coffee with 200 grams of 95 degree water.

Add the coffee to the AeroPress, then pour all the water to the AeroPress and give it a quick swirl with a spoon.

Put the AeroPress plunger into the top of the AeroPress about 1 cm and then pull back slightly to create a vacuum.

Let the coffee steep for 1:30.

Slowly plunge the AeroPress for 30 seconds ending at a total brew time of 2 minutes.

Moka Pot

Coffee Grind 3-4

Depending on the size of the Moka pot will dictate how much coffee to use.

Boil some water in a kettle and warm your element to medium low.

Fill the Moka water chamber to just below the steam spout with your
boiled water, make sure not to cover it.

Place the coffee in the basket and level it off, do not pack it down.

Place the basket in the Moka pot and screw the lid on.

Place the Moka pot on the element and open the lid of the Moka pot.

Let the coffee brew and it will rise to the upper chamber and make a
hissing sound when it is done.

Remove it from the element, close the lid and serve.

French Press

Coffee Grind 8-9

We use 75 grams per litre (depending on the size of your French Press).

Put the coffee on the French Press.

Pour the required amount of 95 degree water and let it steep for 4

Use a spoon to break the crust and let the coffee fall to the bottom of
the vessel.

Put the French press lid on and only plunge to the top of the water.

Let the coffee steep for another 5 minutes.

Push down the plunger ¾ of the way, never touching the coffee bed on
the bottom.

Pour your coffee.


Coffee Grind 2-3

Depending on your basket size will depend on the amount of coffee to use.

We use 18 grams of coffee to yield about 36 grams of coffee.

Your brew should take between 27-33 seconds to pour according to your taste preference. The longer amount of time the more extracted and possibly bitter it could be. The shorter amount of time could result in under-extracted, lighter body and possibly sour tasting coffee.
