On this page we always post what coffees we have in store. Since we buy coffees that are offered in-season, the house blend BlackJack and filter coffees always change. This is what makes our coffees so interesting because you always get something different. Stop by often and be surprised by our offerings. All coffees are also for sale at the shop so you can take it home with you and experiment with it.

Since January 2016, we roast our own coffees. We started with a 1kg roaster but demand made us decide that we changed to a Giesen W6-A. We now roast all our coffee ourselves in The Big Building, a co-op community building behind Groningen’ Central Station. However, the capacity of the greens is limited so we still order small batches of greens from Caffenation. All these coffees are available in the cup and in the bag for you to take home!

Burundi Nemba, Kayanza

Nemba washing station lies in the northern province of Kayanza. This region is one of Burundi’s coffee regions with the best quality reputation. Kayanza owes this reputation to its high elevations, rich red soils and dedicated producers. Yet, optimal growing conditions alone aren’t enough to produce a high-quality coffee. This is where Nemba coffee washing station and its management come into play.

Nemba washing station is part of a group of washing stations, managed by Greenco. Each washing station is managed and lead by an agronomist. He oversees the implementation of good agricultural practice and farmer education. He collaborates with the producers to ensure they have access to the necessary farming tools. The agronomist also helps farmers determine and implement the practices best suited to the specific growing conditions of their farming plots.
Nemba washing station uses a monitoring system to ensure traceability all along the production and processing chain. All 3000 producers are smallholders owning an average of 330 coffee trees. The farms delivering cherry to Nemba are all located around 1700m near the Kibila forest. Just like its neighbour country Rwanda, Burundi is planted with Bourbon, producing vibrantly fruity cups. The washing station has over two hundred drying tables and can process up to 750 metric tons of coffee cherry.

Greenco is the company that oversees the functioning of Nemba washing station. At a washing station and farm level, the company aims to increase coffee productivity and quality through financial investment, a strong professional team of agronomists and focus on cherry selection. They also further handle the dry parchment once it is fully dried. They mill and grade the coffee to prepare it for export.


Ethiopia Chelelektu, Kochere
For the second year in a row, we offer a lot from this famous washing station in Kochere. Chelelektu is a town in the Kochere woreda or district in the Gedeo zone of the Southern Nations, Nationalities, and Peoples’ Region. Kochere lies just south of the Yirgacheffe region, west of Gedeb and northeast of the Oromia region.

Over the years, Chelelektu coffee has become synonymous with quality. It is a barista’s favourite for the coffee competitions. Coffees from Chelelektu are known for their typical Ethiopian origin profile – a vibrant floral profile with soft citrus and peach notes. The beans are incredibly well processed at the washing station in Chelelektu town and were deeply blue-green when we cupped them for the first time. During, processing the skin of the fresh cherry is physically removed using a pulp machine and water. The sugar coating or mucilage around the parchment is removed during the fermentation process. Once fermentation is completed the parchment is thoroughly washed with clean spring water to remove all traces of fermented mucilage. At Chelelektu, the parchment is dried on raised beds under shade for 10 up to 12 days until the bean’s interior reaches 12% moisture. This gentle drying under shade results in a concentrated cup and long shelf life.

The clean and dried beans are stored in a warehouse with a region label and are graded. Typically, the coffees are sold to exporters on the commodity exchange. These exporters can sell to the international coffee market.

Rwanda Karambi

Just like Macuba, Karambi is one of the washing stations that make part of the same international coffee group as 32cup. This vertical integration gives us unique insights in the whole coffee season in Rwanda, from the very start of the season until the export, and every production step in between.

Karambi washing station

Karambi is located in the sector with the same name in the Nyamasheke district, Western province. The altitude in the region starts at 1700 and goes up to 2000m. The Nyamasheke district has the highest concentration of washing station in the entire country. The region lies along the Kivu lake. Growing conditions are optimal here with good altitude, great soil, favourable rainfall – basically everything to produce the best coffees. Which obviously explains the high number of washing stations here!
