An in-depth look at the origins that were used to create Mokum and Braine

In northern Tanzania, This Side Up works with local origin partner Wanza, run by Frank Mlay and Rebecca Trupin, to connect smallholder coffee producers around Mount Kilimanjaro and Mount Meru with international specialty markets. Through this collaboration, Wanza works closely with several farmer groups—including Aranga, Marangu, Masista and Amkeni—whose members cultivate coffee on small plots at elevations between approximately 1,200 and 1,700 meters.

In a sector where coffee is commonly marketed through large cooperative unions and the national auction system, these groups represent a less common model of farmer-led organisations with a higher degree of autonomy. Producers organise themselves in smaller associations that retain decision-making power over production practices, quality development, and collective investments.

Working alongside Wanza, these farmer organisations gain access to international markets while maintaining their independence. Activities such as transparent price discussions, shared quality evaluation through cupping sessions, and improvements in drying and processing practices strengthen farmers’ understanding of quality and their position within the value chain.

For the Municipality of Amsterdam, continuing this sourcing relationship supports farmer agency, inclusive governance, and diversified market access in Tanzania’s coffee sector—contributing to a supply chain that strengthens rural livelihoods while encouraging long-term resilience and quality development.

2025 RECAP

WHAT WENT WELL?

In 2025, one of Wanza’s most significant milestones was the appointment of a full-time extension officer (agronomist)—a first for the organisation—made possible through its long-term partnership with This Side Up and the regenerative premium. Working closely with farmers throughout the season, this role has enabled tailored, farm-specific guidance, strengthening productivity and soil health while helping to minimise quality inconsistencies.

WHAT DID NOT GO WELL?

Wanza—our local origin partners, Frank and Rebecca—found themselves in a difficult position this season, as farmers questioned why This Side Up was paying prices similar to the local market. Expectations naturally rise each year, and it remains challenging to explain the constraints of the European market (opposite problem to Rwanda!) and why an importer does not have complete freedom to increase prices every season.

After more than 12 years of working together, these conversations have not necessarily become easier. If anything, they continue to reflect the deeper, unresolved dynamics of trade, where trust, history, and expectations don’t always move at the same pace. We feel if values align then staying engaged matters more than simplifying the reality!
