Women of Karambi

Recently, the women of Koakaka’s Karambi washing station banded together to create an association, and made the decision to seperate their coffee and market it as their own.

As members of the cooperative, the members are guaranteed a minimum price for their coffee cherries, and are paid a good price to ensure the very best quality cherries are delivered. They also receive a bonus connected to the quality and prices paid for the lots of coffee.

By separating their coffees out, the women of the association are able to directly benefit from any higher prices paid specifically for their lots, rather than these profits being shared equally amongst all members.

This creates a very important and effective incentive for them to work to hard as a collective towards achieving the very best quality possible; and we think the results are evident in the cup you’re drinking.

Koakaka Cooperative

In the local Kinyarwanda language, Koakaka stands for the ‘Coffee Growers’ Cooperative of Karaba’. Since 2004 it has been Fairtrade certified, and more recently has UTZ and Rainforest Alliance certifications. They’re also members of the International Women’s Coffee Alliance.

The majority of Koakaka’s members are very small-scale producers who typically own less than a quarter of a hectare of land on which they cultivate an average of only 300 trees, alongside other subsistence food crops such as maize and beans.

Processing

This coffee was processed using the washed processing method at the Karambi Washing Station, using natural spring water from the surrounding mountains.

Members of the Koakaka Cooperative are trained to only select the very ripest coffee cherries from their trees. During harvest, cherries are delivered daily to the Karambi Washing Station by foot, bicycle or driven by truck from a local pick-up point (they have 70 pick points in the surrounding area). The women have specific delivery days to the washing station to ensure their lots are processed seperately.

On delivery, the cherries are inspected and sorted to ensure only the very ripest cherries are processed. They are then sorted by weight (and any floaters removed) and pulped on the same day—almost always in the evening—using a mechanical pulper that divides the beans into three grades. The majority of this processing happens in the blue-roofed buildings you can see in the photo above.

After pulping the coffee is fermented overnight in tiled tanks (for 12 -18 hours) without water and then graded again using floatation channels that sort the coffee by weight (heaviest usually being the best).

The beans are then soaked in clean water for a further 14 hours, before being moved to raised screens for ‘wet-sorting’ by hand—this is a task almost always carried out by women.

The sorted beans are finally dried in the sun on raised screens (‘African beds’) for two weeks – you can see these in the photo at the top of this page. During this period, the coffee is turned several times a day by hand to ensure the coffee dries evenly and consistently. It is also sorted constantly, with any defects removed.

Once dry, the coffee beans are stored in parchment, in carefully labeled day lots, until they are ready for milling and export. The coffee is then sent to Kigali, from where it is milled, loaded, and shipped.

Fresh harvest sourcing

This coffee was harvested in September 2017.

We only source and roast coffee from each country’s latest harvest season (so the green coffee is never older than 1 year from the time of picking, processing and packing).

This ensures the sensory qualities are always at their peak and unaffected by excessive ageing.

Roasted for espresso and filter (best enjoyed black)

Roast style: omni. Omni roasts are designed to brew and taste great both as espresso and filter. Our omni single origins generally sit on Agtron values in the ~70-60 value range. So, technically, they are somewhere in the lighter side of the medium spectrum.

Brewing coffee at home

Best brewed 15–49 days post-roast

When you leave your whole beans to rest (inside the sealed bag) until our recommended window, you’re brewing at optimum flavour and acidity.

This time allows for the gas compounds, absorbed during the roasting process, to leave the coffee. If you brew too early, it may not be bad, but you’ll miss out on each coffee’s best flavour.

Do you source your coffee ethically? How so?

We source our coffee from small growers, producers, and cooperatives through responsible importing companies; 95% of our green coffee beans are supplied by Caravela Coffee, Cafe Imports, Osito, and Melbourne Coffee Merchants (certified B Corporations), plus Condesa Co Lab, Cofinet, and a few more.

We share all the traceability information we have about each coffee lot (territory of origin, producer, variety, processing method, importer, quality grade) on each dedicated coffee page. This applies to the blend components in our espresso blends.

Learn more about our coffee philosophy.

Do you roast dark or light?

We roast our single origins using omni roast medium/light profiles. (Omni means you can use the coffee both for filter and espresso brewing, no need to buy different bean bags with specific roast styles.)

We roast our espresso blends using darker profiles.

What is ‘specialty coffee’?

The definitions and references to specialty coffee are tricky, if not controversial.

Historically, and as most people see it these days, specialty coffee is Arabica beans that score over 80 in the old Specialty Coffee Association point scale. Today, the SCA refers to specialty coffee as “a coffee or coffee experience that is recognised for its distinctive attributes, resulting in a higher value within the marketplace.”

Our single origins are Arabica +85 SCA score and our blend components Arabica +80, which could be considered ‘true specialty’ coffee. Though we prefer to use the term ‘high quality’ and back this claim with solid traceability data.

What’s the benefit of your coffee subscription?

When you subscribe, you get freshly roasted coffee delivered as often as you need, so you don’t have to be so hands-on in planning your coffee purchases.

Also, you get free shipping on every delivery, and you can cancel or pause whenever you need – no lock-in periods.
